Description

The Arista OSFP-400G-XDR4-S is a 400G OSFP optical transceiver from Arista's 400G OSFP optics range, built for data-centre links of up to 2km over parallel single-mode fibre. It runs 400GBASE-XDR4 and suits operators who need to break a 400G port out into four 100G links.

The module carries four 100G lanes at 1310nm over parallel SMF (G.652) and interoperates optically with 4x 100GBASE-FR optics up to 2km. This -S variant uses SN optical connectors, whereas the OSFP-400G-XDR4 uses MPO-12 APC. Transmit power is -2.4 to +4.0 dBm per lane and receive power is -6.4 to +4.5 dBm per lane. Maximum power consumption is 12W, drawn from the host OSFP port. The module is hot swappable, with an operating case temperature of 0 to 70 C.

It fits OSFP ports on Arista platforms. The QSFP-DD equivalent with SN connectors is QDD-400G-XDR4-S.

FAQs

Q: What is the difference between OSFP-400G-XDR4-S and OSFP-400G-XDR4?
A: The -S variant uses SN optical connectors, while the OSFP-400G-XDR4 uses an MPO-12 APC connector. Both run 400GBASE-XDR4 over parallel single-mode fibre.

Q: Can it link to 100GBASE-FR optics?
A: Yes. It is optically interoperable with 4x 100GBASE-FR optics at distances up to 2km, which allows a 400G port to break out into four 100G links.

Q: What host port does it need?
A: It needs an OSFP port on a supported Arista platform. Check Arista's Transceiver and Cable Guide for the supported platform list.

Q: Is there a QSFP-DD version with the same connector?
A: Yes. The QSFP-DD equivalent with SN connectors is QDD-400G-XDR4-S.

Q: How much power does the module draw?
A: Maximum power consumption is 12W, drawn from the host OSFP port.
