Description

The OSFP-400G-VSR4 is a 400GBASE-VSR4 optical transceiver in the OSFP form factor, built for short-reach 400G links over parallel multi-mode fibre. It suits in-rack and intra-data-centre switch interconnects where a high-speed link is needed over a short run.

It connects through an MPO-12 APC interface at 850 nm and reaches up to 50m over OM4 parallel multi-mode fibre, or 30m over OM3. Transmit power is +4.0 to -4.6 dBm per lane and receive power is +4.0 to -6.3 dBm per lane. Maximum power consumption is 12W. The module is hot swappable and has an operating case temperature range of 0 to 70 C.

It fits OSFP ports on Arista platforms. The QSFP-DD equivalent is QDD-400G-VSR4.
