Description

The Arista SFP-1G-SX is a 1000BASE-SX SFP optical transceiver that carries Gigabit Ethernet over duplex multimode fibre at 850nm using a standard LC connector. It suits short-reach links such as in-building, data centre and campus switch-to-switch or switch-to-server connections.

On 50um fibre with 500 MHzkm modal bandwidth (OM2) it reaches up to 550m, dropping to 500m on 400 MHzkm fibre. On 62.5um fibre it reaches 275m at 200 MHzkm and 220m at 160 MHzkm. Transmit power is -9.5 to -4.0 dBm and receive power is -17 to 0.0 dBm. The module draws a maximum of 1 W from the host port and has no PoE function. This is the multimode 1000BASE-SX variant, distinct from the SFP-1G-LX, which runs at 1310nm over single-mode fibre for 10km.

The module fits SFP and SFP+ ports on Arista platforms, with the supported platform matrix listed in Arista's Transceiver and Cable Guide. For 10G host ports on specific platforms, the rate-adapting SFP-10G-RA-1G-SX is the alternative part.
