Network Transceiver Module Trendnet TEG-MGBS80

The Trendnet TEG-MGBS80 Mini-GBIC single-mode transceiver module fits standard Mini-GBIC (SFP) slots on most switches and provides long-reach fibre connectivity. It uses 1550 nm wavelength and a 1000Mbps-LX (LC-type) interface to support single-mode links up to 80 km (49.7 miles), enabling reliable data transmission for extended-distance network segments.

Advantages

The module offers long-distance link capability up to 80 km while maintaining gigabit Ethernet performance, uses a common LC connector for easy installation, and is compatible with standard Mini-GBIC/SFP slots. Its single-mode design and 1550 nm wavelength are suitable for extended-reach fibre runs in campus, metropolitan, or inter-building networks.

Suitable for

• Connecting switches over long-distance single-mode fibre
• Campus, data centre uplinks and inter-building links
• Metro Ethernet and long-haul network segments

Key specifications

• Brand: TRENDNET
• Model / MPN: TEG-MGBS80
• Form factor: Mini-GBIC / SFP (LC-type)
• Data rate: 1000 Mbps (LX)
• Wavelength: 1550 nm
• Maximum distance: 80 km (80,000 m / 49.7 miles)

How to use

Insert the TEG-MGBS80 module into a compatible Mini-GBIC/SFP slot on the switch until it latches, then connect a single-mode LC fibre patch cable to the module’s LC port. Configure the switch port for 1000 Mbps (auto-negotiation or forced LX as required) and verify link status through the switch management interface or status LEDs.

Recommendations

Use single-mode fibre with appropriate LC connectors and maintain proper fibre handling practices. Verify switch compatibility with the Trendnet TEG-MGBS80 and ensure transceiver firmware or vendor restrictions do not block third-party modules. For distances near 80 km, verify optical budget and use suitable amplifiers or dispersion compensation if necessary.
