Arista 1000BASE-SX SFP Transceiver Module, Multimode LC

Gigabit over multimode fiber is the function of the Arista 1000BASE-SX SFP Transceiver Module, part number SFP-1G-SX. It runs at 1GbE, uses a duplex LC connector and fits the SFP form factor with one port.

Confirm the supported distance and fiber grades with the manufacturer's data before you rely on it. In general, 1000BASE-SX modules are meant for short links inside a building, such as switch-to-switch connections and uplinks from older access gear.

This part is useful when you operate a mix of speeds. A switch with SFP+ cages can often take SFP modules at 1GbE, which lets one chassis serve both gigabit and 10GbE neighbors. Check your platform documentation to confirm that the cage you intend to use accepts it at 1GbE.

Both ends of the link need compatible modules and multimode fiber. Arista switches maintain a list of supported optics, and devices from other vendors may have their own rules, so check each side.

Because the connector is LC, standard duplex multimode patch cords apply.

The SFP-1G-SX is offered new and refurbished, each with a choice of 1 year or 3 years of warranty. No used offer is listed. Send your quantity and platform when you request pricing.
