Our take on the Juniper EX-SFP-1FE-LX | 100Mb/s 100Base-LX Single-Mode Fibre 1310 nm 10 km Duplex LC connector SFP Transceiver Module

The Juniper EX-SFP-1FE-LX is a 100Base-LX optical transceiver that plugs into an SFP slot and runs Fast Ethernet over single-mode fiber. It transmits at 1310 nm and reaches up to 10 km over duplex LC single-mode cable. It is a genuine Juniper part aimed at EX switches and other Juniper gear in campus or building-to-building links. Against generic third-party 100Base-LX modules it costs more but carries Juniper's compatibility assurance and support; against 1000Base-LX it is slower but suits legacy 100 Mb/s links.
