Small rectangular SFP transceiver module with a single LC simplex port and metal housing

TRENDnet

TRENDnet TEG-MGBS40D3 SFP transceiver 40km TX 1310nm RX 1550nm

SKU CH-FBFF-WK0ZQ

Single-mode bi-directional SFP module transmitting at 1310nm and receiving at 1550nm over one fibre strand up to 40km at 1.25Gbps

  • Up to 40km reach for long-haul fibre links
  • 25Gbps data rate supports Gigabit Ethernet throughput
  • Bi-directional WDM uses single strand LC simplex
  • TX 1310nm / RX 1550nm wavelength pairing for dual-wavelength operation
  • IEEE 802.3z compliant for standards-based interoperability

TRENDnet BiDi SFP Transceiver

The TEG-MGBS40D3 is a bi-directional single-mode SFP transceiver designed for gigabit fibre links. It uses wavelength-division multiplexing to send and receive over one LC simplex strand, fitting standard SFP ports on switches and media converters.

Who this suits and who should look elsewhere

Network engineers extending campus or metro links up to 40 km will appreciate the 1.25 Gbps throughput and low EMI design. Buyers who need a complete point-to-point link must also acquire the matching TEG-MGBS40D5 module, as this unit cannot operate alone.

Capacity and headroom

The module delivers reliable 1.25 Gbps gigabit Ethernet over distances of 40 km or 24.85 miles, compliant with IEEE 802.3z. Beyond that reach or for multi-gigabit speeds the transceiver reaches its limit and a different optic would be required.

Highlights

  • Up to 40km reach for long-haul fibre links
  • 25Gbps data rate supports Gigabit Ethernet throughput
  • Bi-directional WDM uses single strand LC simplex
  • TX 1310nm / RX 1550nm wavelength pairing for dual-wavelength operation
  • IEEE 802.3z compliant for standards-based interoperability

Questions about this item

Which companion module must I already have so this transceiver can form a link?

The module must be paired with a TEG-MGBS40D5 unit or another compatible single-mode BiDi module operating at the opposite wavelengths.

Will this module work in my older switch that only has standard SFP ports?

Yes, it fits any standard SFP slot and complies with IEEE 802.3z Gigabit Ethernet for 1.25Gbps operation.

After installation, what shows the 40km single-strand link is healthy?

A steady link LED on the switch port and a clean RX optical level in the management interface confirm the 1310nm/1550nm path is active.
