ORing SFP1G-LX20-I SFP transceiver 1Gbps single-mode 20km 1310nm -40 to 85°C

Industrial-grade SFP transceiver

The ORing SFP1G-LX20-I is a hot-pluggable SFP optical module built for single-mode fibre links up to 20 km. It operates at 1 Gbps with a 1310 nm transmitter and a 1260 to 1610 nm receiver, housed in a 2.75 x 0.59 x 0.39 inch package weighing 17g. The extended temperature rating of -40 to 85 ℃ makes it suitable for outdoor cabinets and industrial switches where commercial-grade parts would fail.

Duplex LC connector and monitoring

A standard duplex LC interface plugs directly into compatible switches or media converters without adapters. The module complies with IEEE 802.3z and Fibre Channel 100-SM-LC-L, draws power from a 3.3 V supply, and uses LVPECL data lines with TTL signal-detect for link monitoring. Class 1 laser certification to EN 60825-1 allows safe live insertion and removal in the field.

20 km reach with defined power budget

Transmitter output ranges from -8 to -2 dBm into single-mode fibre, while the receiver accepts -1 to -23 dBm, giving a practical link budget for the rated 20 km distance. The wide optical input window handles attenuation from splices and patch panels without exceeding sensitivity limits. Networks needing longer spans or higher data rates such as 10 Gbps will require different transceivers.
