Description

This 400G OSFP transceiver is built for 400GBASE-XDR4 links of up to 2km over parallel single-mode fibre. It can also break out to four 100GBASE-FR channels, which suits data centre spine and leaf links and 400G-to-100G breakout designs where each channel is patched separately.

The -S variant uses four individually pluggable duplex SN connectors instead of a single MPO-12, so each 100G channel can be patched on its own with no breakout cable or cassette. It operates at 1310nm over G.652 single-mode fibre, with a per-lane transmit power of -2.4 to +4.0 dBm and a receive power of -6.4 to +4.5 dBm. Maximum power consumption is 12W, drawn from the host OSFP port, and a pull tab latch simplifies removal. The module is hot swappable.

It is designed for Arista OSFP ports running EOS 4.24.0 or later and interoperates with 400G-XDR4 OSFP and QSFP-DD optics as well as 100GBASE-FR QSFP optics. The OSFP form factor is not compatible with QSFP-DD ports. The non-S version, OSFP-400G-XDR4, uses an MPO-12 APC connector instead.

FAQs

Q: What is the difference between OSFP-400G-XDR4-S and OSFP-400G-XDR4?
A: The -S variant uses four individually pluggable duplex SN connectors, while the non-S version uses an MPO-12 APC connector. The -S suits designs where each 100G channel is patched separately.

Q: Can this module be used in a QSFP-DD port?
A: No. This is an OSFP form factor module and is not compatible with QSFP-DD ports. It requires an OSFP port.

Q: What software version is required?
A: Arista OSFP ports must be running EOS 4.24.0 or later to support this transceiver.

Q: Can it break out to 100G links?
A: Yes. It interoperates with 4x 100GBASE-FR QSFP optics over single-mode fibre up to 2km, with each 100G channel on its own SN connector.

Q: Does it need external power?
A: No. It draws a maximum of 12W from the host OSFP port and needs no external power.
