Single-mode SFP transceiver for 80 km links

The TRENDnet TEG-MGBS80 is a single-mode SFP module with a duplex LC connector operating at 1550 nm. It delivers 1.25 Gbps Gigabit Ethernet and 1.0625 Gbps Fibre Channel connectivity over distances up to 80 km. The module draws power from a single 3.3 V supply and fits any standard SFP slot. It is built for network engineers extending fibre runs between sites.

Who this suits and who should look elsewhere

This module suits administrators linking two switches or a switch and a file server across campus or metro single-mode fibre up to 80 km. It is not for multimode fibre installations, nor for links that require a different wavelength or a reach beyond 80 km. Buyers needing copper RJ45 connectivity or shorter-reach optics should choose a different module.

Deciding specification: 80 km single-mode reach

The 80 km single-mode distance rating at 1550 nm is the parameter that determines whether this transceiver matches the link budget. Verify that the fibre path loss and connector losses stay within the module’s budget before purchasing. Compliance with IEEE 802.3z and a 3.3 V power requirement are baseline expectations for any standard SFP slot.

Questions about this item

How do I install the TRENDnet TEG-MGBS80 into a Mini-GBIC slot, and what step do people often miss?

Insert the module until the latch clicks, then connect the duplex LC fiber cables matching the 1550 nm wavelength; the step often missed is confirming the link light before assuming the 80 km range is active.

What maintenance or replacement will the TEG-MGBS80 need over time?

The 3.3 V power supply and LC connectors are the only serviceable parts; dust the LC ferrules periodically and replace the module if the 1.25 Gbps link drops below the 802.3z error threshold.

What limit appears first when the TEG-MGBS80 runs continuously at full load?

The 1550 nm laser’s optical budget for 80 km single-mode fiber is the first constraint; sustained 1.25 Gbps throughput cannot exceed the IEEE 802.3z reach specification.
