125M/155M SFP Transceiver for 20 km Links

This Ficer Technology SFP transceiver delivers 125 Mbps Fast Ethernet and 155 Mbps SONET or SDH connectivity over single-mode fibre. It uses a 1310 nm FP laser and a duplex LC connector to reach link distances up to 20 km. The module complies with IEEE 802.3ah 100BASE-LX10, SONET OC-3 IR-1 and SDH STM-1 S-1.1 standards.

Hot-pluggable SFP MSA module

The unit follows the INF-8074i SFP multi-source agreement and draws power from a single 3.3 V supply. A two-wire management interface compliant with SFF-8472 provides real-time diagnostic monitoring. Hot-pluggable operation allows insertion or removal without powering down the host switch or router, provided the equipment accepts coded SFP modules.

Extended-temperature operation for sustained 20 km

Commercial-temperature rating supports continuous operation across the rated distance without active cooling on the transceiver itself. The 1310 nm transmitter maintains stable output during prolonged Fast Ethernet or OC-3/STM-1 traffic. Buyers who need reaches beyond 20 km or multi-mode fibre compatibility should select a different model from the same speed class.

Questions about this item

What limits the link distance to 20 km over single-mode fiber?

The 1310 nm FP laser and receiver sensitivity are engineered for 20 km reach on single-mode fiber at 125/155 Mbps.

How much power does the module draw and does it need extra cooling?

It runs on a single 3.3 V supply and complies with the SFP MSA thermal envelope, so standard host airflow is sufficient.

Which host equipment must I already own for this transceiver to work?

You need a switch or router with an SFP cage that accepts INF-8074i MSA modules and supports 100BASE-LX10 or OC-3/STM-1 rates.
