Network transceivers for 40 km links

The TRENDnet TEG-MGBS40 is a Mini-GBIC module designed for single-mode fibre runs up to 40 km. It fits standard SFP slots on compatible switches and routers. The module operates at a 1310 nm wavelength with a duplex LC optical interface. It targets network administrators extending Gigabit Ethernet between buildings or across campuses.

Sustained throughput at 1.25 Gbps

The transceiver supports data rates up to 1.25 Gbps continuously, not just in short bursts. It complies with IEEE 802.3z Gigabit Ethernet and ANSI Fibre Channel standards for reliable long-haul transmission. Low electromagnetic interference design helps maintain signal integrity over the full 40 km distance. The module delivers consistent 1000 Mbps LX performance without degradation.

Hot-swappable LC connector build

The duplex LC connector ensures precise fibre alignment for daily connect and disconnect cycles. Hot-swappable Mini-GBIC form factor allows installation without powering down network equipment. The 0.4120 kg weight reflects a compact, ruggedised housing suited for dense switch deployments. Buyers needing multimode fibre or shorter reach should select a different module.

Questions about this item

How much power does the TEG-MGBS40 draw when running continuously in a switch?

The TRENDnet TEG-MGBS40 is a passive SFP transceiver with no active cooling, so it adds negligible heat and draws only the milliwatts required by the 1.25Gbps optical interface.

What slot type and fiber patch cable does the TEG-MGBS40 require to operate?

It needs a standard Mini-GBIC (SFP) slot on the host switch and a duplex single-mode patch cable with LC connectors for the 1310nm link.

Will the TEG-MGBS40 work alongside older 1000Mbps-LX gear already in the rack?

Yes, it complies with IEEE 802.3z Gigabit Ethernet and ANSI Fibre Channel, so it interoperates with existing 1000Mbps-LX single-mode equipment at 1310nm.
