SFP28 Cable: Why Choose It?

Over the years, our demand for communication bandwidth requirements has increased dramatically. Communication service providers, public or private data centers require higher speed and bandwidth connections. At this time, a new Ethernet connectivity standard, 25 Gigabit Ethernet was proposed. The release of the 25G Ethernet standard has provided a new path for data center server connections. This article will discuss 25G SFP28 cable and why you should choose it.

What Is SFP28 Cable?

SFP28 cable, also known as SFP28 DAC (Direct Attach Copper ) Twinax cable or SFP28 AOC (Active Optical Cable) cable, is a form of a high-speed cable with SFP28 connector on either end. It features with lower power consumption and lower interconnection loss, which makes it suitable for TOR (Top-of Rack) switch to server connectivity.

How Many Types of SFP28 Cable？

The SFP28 cable can be classified to 25G SFP28 DAC cable and 25G SFP28 AOC cable. And they are all present to be the most economical choice for TOR 25gbe switch connections. Here we will explain each cable one by one.

25G SFP28 DAC Cable

SFP28 DAC is a form of a shielded high-speed SFP28 cable with pluggable transceivers on either end. Generally, there are two popular types of SFP28 DACs on the market, 25G SFP28 to SFP28 DAC and 100G QSFP28 to 4 SFP28 DAC. 25G SFP28 to SFP28 DAC cable is usually a passive cable on the market. It has no signal amplification in the cable assembly, so it’s often used for ultra short reach (≤5m). 100G QSFP28 to 4 SFP28 DAC uses breakout cables connect to a 100G QSFP28 port switch on one end and four 25G SFP28 ports switch on the other end, making it a highly cost-effective way to achieve short distance. Normally 25G SFP28 DAC can be used to the interconnection of switches, routers, storage devices, and servers.

25G SFP28 AOC Cable

SFP28 AOC has a similar appearance as SFP28 copper cable, but its transmission method and application environment are not the same. There are two types of SFP28 AOCs on the market, 25G SFP28 to SFP28 AOC and 100G QSFP28 to QSFP28 AOC. SFP28 AOC uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable. Compared to the SFP28 copper cable, SFP28 AOC usually has a longer transmission distance and better transmission performance. Compared with the optical transceiver module, it does not have the problem of the interface being contaminated, which greatly improves the stability and reliability of the system and reduces the management costs of the server room. SFP28 AOC cable is the ideal cable for the connection between rack and rack on a data center, which is generally optimized for lengths.

Benefits of 25G SFP28 Cable Connections

The development of 25G SFP28 cable connections has provided a wide range of benefits, especially in a web-scale data center environment. Primarily, SFP28 cable is suitable for short-distance cabling of a network solution, which has a scientific layout design to save space with more reasonable length. It can efficiently utilize data and switch port density. Moreover, SFP28 cable provides an extremely efficient increase in speed to the server to TOR, especially when using the DAC assembly. It also simplifies the development of interoperability specifications and systems due to the fact that it is backward compatible and gives an easier upgrade path from an existing 10G TOR server configuration. Furthermore, using 25G SFP28 cables for TOR servers are more economical. This is because SFP28 cable can provide higher port densities, fewer TOR switches and cables are needed. It allows a more cost-effective alternative TOR server connection that connects via point-to-point links. It also enables EOR (End of Row) or MOR (Middle of Row) by using structured cabling.

The Future of SFP28 Cable Connections

25G SFP28 cable solutions feature a lower power consumption and smaller footprint requirement for data centers. Due to the benefits provided by 25G SFP28 cable assembly, it is expected that it will be popular in the years to come. It is believed that the dominant next-generation server connection is towards the 25Gbps speed in the server. And in the near future, more devices will use the 25G SFP28 DAC or AOC cable assembly solutions. FS.COM offers a variety of SFP28 DAC/AOC options, such as SFP-H25G-CU3M, SFP28-25G-AOC1M and so on.

Data Center Cabling Solution: Active Optical Cable

As data rates rise and data center grows in size, copper cable is getting stretched to its limits. However,  active optical cable (AOC) has emerged to replace copper cable in data centers and high-performance computing (HPC) applications. It provides high-speed, high reliability, high flexibility, and low power consumption. This article will provide some knowledge of AOC cable. 

What is an Active Optical Cable?

Active optical cable (AOC) is an optical fiber jumper cable terminated with optical transceivers on both ends. It uses electrical-to-optical conversion on the cable ends to improve the speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.

Active Optical Cable Structure

AOC cable consists of the fiber optic connector and fiber cable. The connection between fiber cable and fiber optic connectors is not separable. If the fiber optic connector or fiber cable needs to be changed, they should be removed together. The electrical and optical signal conversion can be achieved right through each end of the optical fiber.

Active Optical Cable Types

There are several varieties of AOC cable available on the market , including 10G SFP+ AOC, 25G SFP28 AOC,40G QSFP+ AOC, 56G QSFP+ AOC, 40G QSFP+ to 4x SFP+ breakout AOC, 40G QSFP+ to 8x LC breakout AOC, 100G QSFP28 AOC, 100G QSFP28 to 4x SFP28 breakout AOC and 120G CXP AOC, etc. These AOC cables are commonly used for short-range multi-lane data communication and interconnect applications between two devices, such as rack-to-rack, shelf-to-shelf interconnect, storage, hubs, switches, routers, servers, etc.

Features and Benefits

AOC cable provides low power consumption, high density, high speed, high reliability, high security, small size, strong heat dissipation, low electromagnetic interference, long transmission distance, low energy consumption, low latency, lightweight, and ease of installation.

Application Scenarios

AOC Cable is used to connect top-of-row (ToR) switches to end-of-row aggregation switches, and to connect the ToR switch with storage subsystems at reaches greater than direct attach copper (DAC) limits of 3-7 meters. The following three scenarios show the specific applications.

Scenario 1:  AOC cable is used to connect two switches directly.

Scenario 2: The breakout AOC cable provides a highly cost-effective way to connect within racks and across adjacent racks. The following figure shows 40GbE QSFP+ to 4 x SFP+ AOC cable connecting to a 40G QSFP+ port switch on one end, and to four 10G SFP+ port switches on the other end.

Scenario 3: For the long-haul transmission between the two switches, a suitable solution is recommended to use single-mode patch cable, OEO converters, and AOC cables, which can provide seamless integration of different fiber types by converting multi-mode fiber to single-mode fiber.

Conclusion

AOC cable achieves high data rates over long reaches interconnection, which is the best solution for data centers and high-performance computing applications.

Know About QSFP28 Port Using QSFP+ Optics

The form factor of cisco QSFP28 transceivers is the same as that of the QSFP optical transceiver. The latter supports 40G, whilst the former only provides 4 electrical lanes that may be utilized as 4x10GbE or 4x25GbE. According to all of this data, a QSFP28 module splits either 4x25G or 4x10G lanes, depending on the transceiver being utilized. The SFP28 transceivers, which run at a slower 10G speed and accept SFP+ transceivers, exhibit the same behavior.

Both QSFP+ and QSFP28 optics may often be used with a 100G QSFP28 port. The QSFP28 optics can run 4x25G breakout, 2x50G breakout, or 1x100G if they support 25G lanes. The QSFP+ optic can operate 4x10GE or 1x40GE since it supports 10G lanes. Keep in mind that there are Twinax/AOC and single-mode and multimode (SR/LR) optical transceivers available if you employ QSFP transceivers in QSFP28 ports.

QSFP28 Optics Cannot Ever Be Used on QSFP+ Port SFP+ cannot automatically negotiate to support SFP modules, and cisco QSFP cannot be utilized on a QSFP port. It boils down to the optic and the port, and vice versa, according to the rule regarding combining optical transceivers with various speeds. The form factor and both ends of the two modules must be compatible. Additionally, the port speed must match or exceed the optical speed. When selecting the best MTP trunk cable for a 40G QSFP+ SR4/CSR4 transceiver connection, there are several other aspects to take into account in addition to employing an MTP 8-fiber or MTP 12-fiber trunk cable.

Conclusion In conclusion, QSFP+ modules can be utilized on QSFP28 ports however QSFP28 transceivers are unable to transmit 100Gbps on QSFP+ ports. Don't forget to set up your switch before utilizing the QSFP optics on the QSFP28 port. We must select a female-female MTP trunk cable if we wish to properly link a 40G QSFP+ SR4 transceiver to another 40G QSFP+ SR4 transceiver. We must choose a type B MTP 8-fiber or MTP 12-fiber trunk cable under the IEEE 40GBASE-SR4 requirements. You must make sure that the connections on both ends are identical and that there are no problems with manufacturer compatibility to guarantee a smooth network transfer. You can opt for cisco SFP.
