Description

The OSFP-400G-SR8-C is a 400GBASE-SR8 OSFP optical transceiver from Arista's 400G OSFP optics range. It is built for short-reach data centre links over parallel multi-mode fibre, including 400G switch-to-switch connections and breakout or interop with 50G and 25G SR ports.

It uses an 850 nm wavelength and an MPO-16 APC connector, reaching 100m over OM4 parallel multi-mode fibre or 70m over OM3. The -C variant supports 400GBASE-SR8 and also 8x 50G / 25G-SR operation, which separates it from the OSFP-400G-SR8 that supports 400GBASE-SR8 only. Maximum module power consumption is 12 W and the operating case temperature range is 0 to 70 C.

The module fits OSFP ports on Arista switches. Supported platforms are listed in Arista's Transceiver and Cable Guide, so check it for breakout support on your switch. The QDD-400G-SR8-C is the QSFP-DD equivalent of this module.

FAQs

Q: How does the -C variant differ from the OSFP-400G-SR8?
A: The OSFP-400G-SR8-C supports 400GBASE-SR8 and also 8x 50G / 25G-SR operation. The OSFP-400G-SR8 supports 400GBASE-SR8 only.

Q: What fibre and reach does it support?
A: It uses parallel multi-mode fibre with an MPO-16 APC connector. Reach is 100m over OM4 and 70m over OM3.

Q: What power does it draw?
A: Maximum module power consumption is 12 W. It runs on the host switch port and needs no separate power supply.

Q: Which switches does it work with?
A: It fits OSFP ports on Arista switches. Supported platforms are listed in Arista's Transceiver and Cable Guide, so check it for breakout support on your platform.

Q: Is there a QSFP-DD version of this module?
A: Yes. The QDD-400G-SR8-C is the QSFP-DD equivalent for switches with QSFP-DD ports.
