EX-SFP-1FE-FX Overview
Fast Ethernet multimode SFP
EX-SFP-1FE-FX is a 100BASE-FX Fast Ethernet optic rather than a Gigabit Ethernet module. Juniper specifies an LC connector, 1310nm wavelength and up to 2km reach on multimode fiber.
Port and platform qualification
100BASE-FX requires a host port that supports 100Mbps optical operation. Juniper HCT lists exact supported platforms and software releases; verify the intended chassis, port and Junos release rather than treating every SFP cage as Fast Ethernet capable.
Migration use case
This module is relevant when preserving a legacy 100BASE-FX multimode link. If both endpoints can move to Gigabit Ethernet, evaluate a coordinated upgrade rather than assuming the existing fiber and remote device will negotiate automatically.
Acceptance test
Confirm LC polarity, fiber type and optical budget, then force or configure the documented port speed where required. Check alarms and error counters at both ends before handover.
