SFP transceiver for 125/155 Mbps Fast Ethernet or OC-3 links up to 2 km over multi-mode fibre at 850 nm with duplex LC connector
This SFP module delivers 125 Mbps Fast Ethernet or 155 Mbps SONET OC-3 links over multi-mode fibre up to two kilometres. It targets data-centre operators and campus networks that need hot-pluggable 850 nm optics for legacy 100Base-X equipment.
The duplex LC connector and 3.3 V supply make physical insertion straightforward in any INF-8074i compliant cage. The main friction point is vendor coding: the unit must be programmed for the exact switch brand and model before deployment, so provide that detail at order time.
Multi-mode reach stops at two kilometres at 850 nm; longer spans require single-mode variants not covered here. The 125/155 Mbps rate caps throughput at Fast Ethernet or OC-3 levels, ruling out Gigabit or 10 Gigabit uplinks.
