Asynchronous (Rift era, pre-Crisis, not nearly as much sc angst as the gif implies)
Where am I?, Kara thought, her body shaking as she pushed herself off the floor she had apparently crashed into, trying to stand. How long was I unconscious?
Her head was killing her. Pain was a rarity under a yellow sun, and in this case the feeling was hard to shake - it was just all too reminiscent of not long ago, when she was trapped in kryptonite, fighting burning lungs and a blinding headache while fighting heartbreak at the same time.
But she needed to not think about Lena right now.
Kara searched her mind for the last thing she remembered, Brainyâs words transmitted to her ears, telling her about the capabilities of the alien creature she was fighting. The creature was generally docile enough - but in a panic, it would thrash and quake, and it had the unique ability toâŠ
Where⊠When am I?, Kara thought, looking around at the building whose ceiling she had fallen into. The creature could send her anywhere in time and space - forward or back in time, across the planet or galaxy, it didnât matter. The good news is that the effect would be temporary in nature, lasting a day at most, before she snapped back into place, something about attenuated vibrations. âTime is like a rubber band,â Brainy had said, though Kara was certain she could hear pain in his attempt to simplify the explanation.
Kara heard the buzz of a portal behind her, the quick cock of a gun. âDonât move,â came the familiar voice. âThese arenât ordinary bullets.â
Kara turned slowly, deflating under the hard eyes of her ex-best-friend. Lena was tense and angry, her finger resting on the trigger, her other hand on a tracking device. My heat signature, Kara thought, Guess she has kryptonite bullets now.
Lenaâs eyes narrowed as she reached to her belt, before tossing vibrant green cuffs in Karaâs direction. âPut those on.â
Kara lowered herself to the floor, taking the cuffs, feeling the burn in her hands. She couldnât really fathom Lena trying to kill her. But after the disruption of Lenaâs Myriad plan, and now being held at gunpoint⊠âLena, what are - what are you going to do?â
âHow do you know my name?â Lena growled.
Karaâs eyes widened. Anywhere in time and space⊠âWho do you think I am?â Kara asked.
âIs that a joke?â Lena asked, as Karaâs mind revved into overdrive. âYou think you can come back, with cartoonish S on your chest, and weâll forget the Third Reich?â
Fear sank into Karaâs stomach. Earth X. âLena, I know this looks like-â
âThrough the portal. Now.â
-----------
Kara found herself sitting in an interrogation room.Â
Her mind was scrambling for what Barry had said had become of Earth X - she remembered that, in the aftermath, the Third Reich had fallen to the Resistance, which was trying to rebuild a non-fascist society. But she knew the balance had to be fragile. The Reich had its proponents.
But Kara didnât have long to think, before another familiar face walked into the room. âWinn!â Kara said, jumping up.
âSit down,â Winn growled back.
Kara tensed, shaking off her confusion as she slowly sank to her chair, as Winn gave Lena a skeptical look. Right, heâs not the Winn I know eitherâŠ
Lena shrugged. âShe knew my name, too.â
âYouâre both my friends,â Kara said softly, âOn my Earth.â
Winn ignored her words, stepping around the table to take a seat at its corner. âWe need to know if the FĂŒhrer is still alive.â
âHeâs dead,â Kara said, meeting Winnâs eyes. âAs is his wife.â
Winnâs eyes narrowed in suspicion.
âI was sent here by accident,â Kara answered. âAt some point in the next day or so, Iâll snap back to my own Earth.â If you donât kill me first, she thought.
âAnd how do I know youâre from another Earth?â Winn demanded.
âYou met my sister,â Kara whispered, thinking back to Alexâs stories when they were separated on Earth X, years ago. âAlex Danvers. On my Earth, sheâs your friend too.â
âYou,â Winn said skeptically. âIâm friends with you.â
âIâm not from your Earth,â Kara said. âIâm not asking you to trust me. Just let me live long enough to go back to my own time.â
-----------
Kara fidgeted as she sat alone in the room again - watching, waiting, itching against the bounds of her kryptonite cuffs.Â
She was certain that Winn and Lena - possibly others - were debating what to do with her. Hopefully they don't just kill me, Kara thought, searching her mind for how she might prove sheâs not from their Earth.
But the door opened again.
Lena stepped in quietly, eyes on Kara. But the anger was subdued from before. She was curious. âLena,â Kara whispered.
The wariness wasnât gone from Lenaâs stance, but she sat across from Kara. âWhatâs it like, on your Earth?â
Kara smiled. My Lena would be curious about the other Earths too, she thought. âThe Third Reich ended in 1945. Weâre⊠far from a perfect world. But we havenât had the struggle that youâve had.â
âAnd you and I are friends?â
Karaâs expression faltered, as she glanced down at her hands. âWe used to be. We used to be best friends.â
âWhat happened?â
Kara bit at her lip, unable to look Lena in the eye. âI betrayed you. You hate me now.â
Lenaâs brows furrowed. âThat doesnât seem to be the sort of thing that would help your cause.â
âIâm not going to lie to you again,â Kara said. âIâve done too much of that. The other you, I mean.â
Lena frowned, and Kara could see some of the tension in her body rise again. âWhat happened to my Earthâs Kara? How did she die?â
âHer heart was dying from too much solar exposure,â Kara said. âI took her up into the atmosphere before her body⊠it started a nuclear reaction.â
âAnd the FĂŒhrer?â
âOliver from another Earth killed him.â
Lenaâs eyebrows briefly raised. âWinn met him, apparently.â
âYeah. My sister was there too.â
-----------
Kara itched at her bonds again, wishing there was a clock she could check. I donât know how much time would be left anyway, she thought to herself. But at least Iâd knowâŠ
She was surprised to hear the door open again. Lena walked through with a cup and some bread, placing both in front of Kara on the table. âYou must be hungry,â she said.
âThank you,â Kara murmured, leaning forward and beginning to eat.
âWhat did you lie to me about?â Lena asked. âOn your Earth?â
Kara swallowed harshly. âI- I kept my kryptonian identity from you. Kryptonians and Luthors donât get along.â
âLuthors?â
Karaâs brow crinkled. âAre you a Walsh, here?â
Lena nodded slowly.Â
âYour motherâŠâ Kara asked. âSheâs alive?â
Lenaâs eyes narrowed. âYes.â
Kara smiled. She got to be raised by Elizabeth, she thought. âAre the Luthors alive? On this Earth?â
âNo,â Lena said. âAlexander Luthor was the last FĂŒhrer, before Oliver Queen. There was a power struggle.â
Kara nodded. âYou were raised by the Luthors. On my Earth. So when I hid my identity, and became friends with you⊠you didnât take it well when you found out.â
Lena looked on curiously. âThe secret? Drove me to hate you?â
Kara shook her head. âThere were other mistakes I made. In the aftermath. I⊠hurt you pretty badly.â
âSo what did I do next?â
âYou tried to brainwash the world.â
Lenaâs eyes widened. âWhy?â
âTo make everyone kind.â
Lenaâs brow raised. I guess that resonates, Kara thought. In a world full of fascistsâŠÂ
âI can see the appeal,â Lena said.Â
-----------
Kara was fascinated. And bored.
Her only company was Lena, on and off. She was grateful when Lena came in with food, and over the moon when Lena came in to exchange Karaâs kryptonite cuffs with far less painful power cuffs.Â
But her moments with Lena were few and far between given her apparent other responsibilities, leaving Kara staring up at the ceiling for long stretches of time.
She found herself torn, thoughts of âWhen will I be able to go home?â warring with âI hope my Lena looks at me like that again someday.â
-----------
âAre you happy here?â Kara asked. âAre you- are you with anyone?â Lena smiled. âI met him a year ago,â she said. âWe butted heads on technical projects. Trying to rebuild our societyâs infrastructure. But something more came of it.â
Kara smiled. âJack?â
Lenaâs eyes widened, and she nodded. âJack.â
Kara nodded too. âIâm glad you have someone.â
Lena tilted her head curiously. âWere we more than friends?â
âYou and Jack? Yeah, on my Earth-â
âNo,â Lena clarified. âYou and I. What were we to each other?â
Oh. âNo,â Kara said, shifting uncomfortably. âWe were only ever friends.â
âIs that all you wanted?â
âI just- donât think itâs relevant to you-â
âI donât know what Iâm like on your Earth,â Lena said, leaning forward on her arms. âBut if someone hurt me so badly that I try to brainwash the world about it, I think that person mustâve meant something to me.â
Kara bit her lip.
Lenaâs brow quirked. âIf your plan is to never lie to me again, that seems like the sort of thing you should tell me. Other me.â
Kara laughed, her heart twinging with joy and pain. âIf we ever get along again, Iâll tell you.â
âPromise?â
âPromise.â
-----------
âWhy are you trusting me?â Kara asked curiously.
âWhat do you mean?â Lena asked, in a tone that was more coy than confused.
âYou just seem less suspicious of me than before,â Kara shrugged. âIn the beginning.â
Lenaâs lips quirked, taking a moment to consider Kara. She then raised her hand, twisting it slightly, causing a small yellow glow to appear. Kara noted in shock that there seemed to be a glow passing over her own body, too. âWhatâs happen- what are you doing?â
âJust making your temporal shift visible,â Lena said. âI scanned you after our first meeting. I canât prove youâre not from this Earth, but I can prove that youâre not where the universe expects you to be right now.â
âIâm sorry, but-â Kara sputtered. âBut are you using magic?â
âLena doesnât have magic on your Earth?â Lena said.
âI canât even get my Lena to believe in magic,â Kara said with a laugh. âRao, this is amazing.â
Kara glanced up, and found Lena smiling.
-----------
âHow long have I been here?â Kara asked.
âAbout 12 hours,â Lena said. âHonestly, Iâd let you go. But Winn said it might cause a panic anyway, if too many people see you walking around.â
Kara sat back for a moment. âYeah, that makes sense.â
-----------
It was at the 17 hour mark - just after Lena had brought in more food - that Karaâs hands began to glow. âWhat are you doing now?â Kara asked.
âNothing,â Lena said, leaning forward to eye the glow. âI think youâre being pulled back.â
âOh,â Kara said, glancing up at the alternate Lena. What should I say? âThank you,â Kara murmured. âThanks for being good company.â
âGive me time,â Lena said gently.
âTime?â
âIâll come to my senses,â Lena said, thinking to herself, nodding. âI- I know thereâs baggage. But at some point, I will come to my senses. Iâll come back to you.â
Kara smiled. âI hope so.â
âGood luck, Kara Zor-El.â
-----------
Kara found herself falling. No longer cuffed, no longer in a dark dusty room - but bathed in sunlight and breathing fresh air. Earth-38, she thought gratefully.
She blinked, shooting upwards in the sky again, hearing shouting in her ear. âKara?â came Brainyâs panicked voice. âKara, are you still there?â
âIâm here,â Kara gasped, looking over National City.Â
âMustâve lost you for a minute,â Brainy said. âThe creature is by the arboretum. Weâve finished making the power net, Jâonn is flying it over.â
Kara glanced to the north, but her ears were fixating somewhere southeast, locating a familiar heartbeat. Weâll figure it out, Kara thought, clinging to Earth X Lenaâs words.
Weâll get there, in the end. âIâm on my way.â

Delve into the Classification of Fiber Optic Pigtail
The network's performance during the installation of fiber optic cables depends on how the wires are connected to the system. When implemented correctly, optical signals would have little attenuation and return loss while traveling via the connection. For 99% of single-mode applications, joining optical fiber is best achieved via a fiber optic pigtail like 12 LC Pigtail. A fundamental understanding of fiber optic pigtails, including varieties of pigtail connectors and fiber pigtail classes, is provided in this post.
Specification for Fiber Pigtail
A fiber optic cable having one end terminated with a factory-installed connector and the other end terminated is called a fiber optic pigtail. As a result, the connector side may be connected to machinery, and optical fiber cables can melt the other side. Pigtail patch cords are used for mechanical splicing or fusion termination of fiber optic cables. For fiber optic cable terminations, high-quality pigtail cables combined with proper fusion splicing techniques yield the best results.
Types of Fiber Optic Pigtails
There exist many varieties of fiber optic pigtails: LC fiber optic pigtails, SC fiber pigtails, ST fiber pigtails, and so on are grouped according to the kind of pigtail connection. Single-mode and multimode fiber optic pigtails are available based on the kind of fiber. Additionally, 6 or 12 fiber optic pigtails like 12LC and 12 SC pigtail are available in the market.
According to Fiber Type
Single-mode (yellow) and multimode (orange) fiber optic pigtails are the two categories. Multimode fiber optic connectors are used to terminate 62.5/125 micron or 50/125 micron bulk multimode fiber cables at one end of multimode fiber optic pigtails. Pigtails for 10G multimode fiber cables (OM3 or OM4) are also offered. The 10G OM3 and OM4 fiber optic pigtail's jacket color is often aqua. 9/125 micron single-mode fiber cable is used in single-mode fiber pigtail cables, which terminate at a single-mode fiber connector on one end.
In summary
In essence, fiber optic pigtails like 12 LC Pigtail are used to splice fibers together so they may be attached to equipment or patch panels. Additionally, they offer a workable and trustworthy method for simpler fiber termination, which significantly reduces labor costs and operational time.
