Industrial SFP Module for Long-Haul Links

The TRENDnet TI-MGBS40 is a Small Form-Factor Pluggable transceiver built for gigabit single-mode fibre connections. It operates at a 1310nm wavelength and reaches distances up to 40 km. The module fits standard SFP slots on industrial switches and media converters. It complies with IEEE 802.3, 802.3u and 802.3z standards.

Suited for Harsh Environments.

This transceiver serves installers who need reliable fibre links across wide temperature extremes, rated from -40 to 85 degrees Celsius. It supports humidity up to 95 percent non-condensing and features low EMI design. It is not intended for copper RJ45 connectivity or multi-mode fibre runs. Buyers needing shorter reach or different wavelengths should select another module.

40 km Single-Mode Reach at 1.25 Gbps

The decisive specification is the 40 kilometre transmission distance over single-mode fibre at 1.25 Gbps data rate. This range determines whether the module spans the required link between sites. The LC duplex connector interface and MSA compliance ensure mechanical fit in compatible host equipment.

Questions about this item

Will the LC connector or optical interface need periodic cleaning or replacement?

The LC single-mode interface is passive and has no moving parts; only the fiber end-faces may need occasional cleaning with approved tools.

What limits continuous operation at the full 1.25 Gbps rate over 40 km?

The optical link budget and receiver sensitivity set the maximum reach; staying within the specified 40 km ensures error-free throughput.

How much heat does the module add inside a switch running 24/7 at 85 °C ambient?

Low EMI design and industrial temperature rating (-40 to 85 °C) mean it dissipates minimal power without exceeding the switch thermal envelope.
