TRENDnet TEG-MGBS10D3 1000BASE-BX BiDi SFP Transceiver, 1.25Gbps, 1310nm TX / 1550nm RX, Single-Mode LC Simplex, 10km

The TRENDnet TEG-MGBS10D3 1.25Gbps Bi-Directional SFP Transceiver provides a single-fiber solution for Gigabit Ethernet and compatible fiber networking applications. Designed for single-mode fiber infrastructure, this optical module supports transmission distances of up to 10km, making it suitable for connecting network switches, fiber converters, and other compatible networking equipment across extended distances.

Using BiDi Wavelength Division Multiplexing (WDM) technology, the TEG-MGBS10D3 transmits data at 1310nm and receives data at 1550nm over one strand of single-mode fiber. This helps reduce fiber usage compared with conventional duplex-fiber connections.

The module features an LC/UPC simplex connector, supports data rates up to 1.25Gbps, and is hot-pluggable for convenient installation in compatible SFP MSA-compliant network ports. Its compact metal enclosure and low power consumption make it suitable for business and enterprise fiber network deployments.

Pairing is essential: The TEG-MGBS10D3 must be connected to a compatible BiDi SFP module with reversed wavelengths, such as the TRENDnet TEG-MGBS10D5 (1550nm TX / 1310nm RX). Both ends of the fiber link must use complementary transceivers.
