Small rectangular SFP transceiver module with SC port and metal housing

AddOn

AddOn 1000Base-BX SFP Transceiver 1550nmTx/1310nmRx 20km SC DOM

SKU CH-WGSX-EHNVN

A single-fibre SFP transceiver for 1 Gb/s links over 20 km with 1550 nm TX and 1310 nm RX wavelengths

  • MSA & TAA compliance ensures broad switch interoperability
  • Bi-directional 1550 nm Tx / 1310 nm Rx wavelengths simplify single-fibre deployments
  • 20 km reach on single-mode fibre extends campus and metro links
  • Digital optical monitoring provides real-time link health visibility

1000Base-BX SFP Transceiver 20km

This AddOn transceiver provides a single-fibre Gigabit Ethernet link over single-mode fibre. It transmits at 1550 nm and receives at 1310 nm, reaching distances up to 20 km with an SC connector and Digital Optical Monitoring. The module is MSA and TAA compliant for broad switch compatibility.

Ideal for long-range single-fibre links

Network operators extending campus or metro connections with bidirectional optics will find this module suited to their needs. Buyers requiring dual-fibre interfaces, shorter-reach multimode variants, or higher-speed 10G formats should consider other transceiver types.

Questions about this item

What limits the 20 km reach of the 1000Base-BX SFP under sustained load?

The 1550 nm transmitter and 1310 nm receiver pair is rated for 20 km over single-mode fibre; sustained use does not change that distance specification.

How much heat does the SC DOM transceiver produce during all-day operation?

As a passive SFP module it draws only the power allowed by the MSA specification, so heat output remains low and constant during continuous 1000 Mbps operation.
