SFP56 optical transceiver modules

Always refer to the Datasheet or QuickSpecs for the switch product to see the current list of supported transceivers.

50G technology, implemented through an SFP56 port, is available on select models within the CX product family. Although 50G SFP transceivers (and 50G DACs) are the same physical size as a 1G, 10G, or 25G technology, the 50G products only work at the 50G speed and only in ports that are 50G-capable; usually marked as SFP56. There are a small number of exceptions such as the tri-speed transceivers which are specifically identified as multispeed.

Models, specifications, and compatibility

SFP56 optical transceiver modules are a single-lane, serial 4-level Pulse Amplitude Modulation (PAM4) technology providing a transmission rate of 50 Gbps and use LC connectors. Note that 50G SFP56 technology can not be split into two 25G flows - it is a single-lane, single-wavelength technology.

50G SR transceivers are not supported for use over MMF OM1/OM2 quality fiber. The IEEE standard did not specify any requirements for use over these types of multimode fiber.

Tri-speed capable 50G

AOS-CX release 10.12.0001 added the interface speed command. This command allows 50G SR, eSR and LR transceivers to be able to connect to remote 10G or 25G SR or LR transceivers. Distances may be limited to the 50G SR, eSR and LR capabilities.

50G transceivers can only be inserted into ports capable of 50G speeds (SFP56) or ports configured for 50G capability (e.g. 8360v2, 6300, 6400 R0X44C/S0348A module).

Despite the tri-speed capability, 50G transceivers cannot be used in a 10G or 25G only port. They identify as a 50G part, so inserting into a port not capable of 50G will result in an incompatible transceiver error message.

The 50G SR, eSR and LR transceivers do not auto-detect the remote speed. The speed must be set on the interface hosting the 50G transceiver product (SR, eSR or LR) end and it will connect to a 10G or 25G SR or LR link.

The distance that the 50G transceivers can reach are limited by the 50G xcvr (see specifications above). A 10G SR over OM4 can reach 400m, but a 50G SR or eSR can only reach the distances (70m - 300m) depending on the MMF type.

Refer to the Fundamentals Guide for the speed command.

R0X43A/R0X43C: 50G optics are not supported in 10G SFP+ ports.

 

R0X44C enables 50G on the ports but requires configuration of interface groups. 50G capability (DACs or optics) is only allowed on the lower ports (even numbers) of the group and disables the use of any other connection in the upper ports (odd numbers).
