Description

This Arista 100BASE-FX SFP transceiver provides a 100 Mbps Fast Ethernet optical link over duplex multi-mode fibre. It uses a 1310nm laser with a standard LC connector and reaches up to 2km, making it a practical choice for connecting Arista switches to legacy Fast Ethernet fibre equipment, and for campus, building and industrial fibre runs.

The module uses the SFP form factor with an SGMII electrical interface towards the host switch. It supports 62.5/50 um multi-mode fibre, with a transmit power of -20 to -14 dBm and a receive range of -8 to -31 dBm. Maximum power consumption is 1.5W, drawn from the host SFP port. The operating case temperature range is 0 to 70 C, and the module is classified as Laser Class 1 or 1M.

This is the multi-mode option. Single-mode 100 Mbps links use a separate 100BASE-LX module. Platform support is listed in Arista's Transceiver and Cable Guide.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What fibre type does this transceiver use?
A: It uses duplex multi-mode fibre (62.5/50 um core) with LC connectors at 1310nm. It is not suitable for single-mode links, which need a 100BASE-LX module.

Q: How far can it reach?
A: It reaches up to 2km over 50 um multi-mode fibre. Reach over 62.5 um fibre is shorter, so check your fibre core size when planning the link.

Q: What speed does it run at?
A: It operates at 100 Mbps (100BASE-FX Fast Ethernet). It is intended for 100 Mbps fibre links and will not run at gigabit speed.

Q: Does it need external power or a licence?
A: No. It draws up to 1.5W from the host SFP port and does not require a separate power supply or licence.

Q: Which switches does it work with?
A: It works in SFP ports on supported Arista platforms. Check Arista's Transceiver and Cable Guide to confirm support for your switch model.
