Arista OSFP-400G-SR8-C-Arista | 400G OSFP Transceiver, 850nm, 100m OM4, MPO-16

Q: What is the maximum transmission distance for the OSFP-400G-SR8-C?
A: This transceiver supports up to 100m over OM4 multimode fiber and 50m over OM3 multimode fiber, making it ideal for intra-rack and short-reach data center connections.

Q: What breakout configurations does this module support?
A: The OSFP-400G-SR8-C supports flexible breakout modes including native 400G-SR8, 2x 200G-SR4, and channelized configurations of 8x 50G-SR or 8x 25G-SR, providing deployment flexibility for various network architectures.

Q: What type of fiber cable is required for this transceiver?
A: An MPO-16 APC terminated multimode fiber cable is required, consisting of 16 fibers (8 transmit, 8 receive). OM4 fiber is recommended for the full 100m reach, while OM3 supports up to 50m.

Q: Is this transceiver compatible with QSFP-DD 400G ports?
A: No, OSFP and QSFP-DD use different physical form factors and are not mechanically compatible. OSFP ports require OSFP modules, though both support 400G Ethernet with 8x 50G electrical lanes.

Q: Does this transceiver require licensing on Arista switches?
A: Optical transceivers themselves do not require software licenses. However, certain features or breakout configurations on the host switch may require appropriate EOS software versions or feature licenses depending on your Arista platform.
