7135LB Series | Optics and Cables

Arista Optics and Cables

The 7135LB Series accepts a wide range of QSFP and SFP optics and cables. The QSFP ports of the 7135LB Series accept QSFP optics

and cables configured at 100GE, 4x 25GE, 40GE and 4x 10GE speeds, while the SFP28 ports accept SFP optics and cables configured at

25GE and 10GE speeds. More information about Arista optics and cables can be found here.

Arista’s Enhanced Performance (E-Series) QSFP and SFP optical transceivers, such as the QSFP-100G-SR4-E, SFP-25G-SR-E and SFP-25G-

LR-E enable 100G and 25GE operation without requiring FEC, eliminating the FEC delay usually present in 100GE and 25GE optical

links. Apart from Arista’s E-Series optical transceivers, 100GBASE-LR4 and certain copper cables, all 100GE and 25GE links require FEC,

while all 10GE and lower data rates do not use FEC.

The table below summarizes the most commonly used optics and cables in the 7135LB platforms. For more details about Arista’s

pluggable optics and cables, refer to the Optics Modules and Cables Data sheet, the Arista Transceiver and Cable Guide, and Arista’s

Enhanced Performance Series Optics Q&A.
