1.25G SFP Transceiver for 40km Links

This small form-factor module delivers 1.25 Gbps over single-mode fibre using a 1310 nm DFB laser and a duplex LC connector. It follows the INF-8074i SFP MSA and supports hot-plug operation from a single 3.3 V supply. The link budget reaches 40 km, making it suitable for campus or metro Ethernet spans.

Network teams extending Gigabit Ethernet

Engineers who need a coded module for a specific switch brand can order the correct vendor ID after confirming the host equipment. It is not intended for multi-mode fibre runs, shorter-reach 10 km or 20 km links, or any application above 1.25 Gbps. Buyers without a compatible SFP cage should look at other form factors.

Handles 40 km single-mode spans at 1.25 Gbps

The optical budget covers campus backbones, building-to-building uplinks and 1 Gbps Fibre Channel at 1.0625 Gbps. Beyond 40 km the received power drops below specification, so longer metro or long-haul paths need higher-reach modules such as 80 km or 120 km variants.

Questions about this item

What type of switch port does the 1000BASE-LHX SFP need to operate?

The module plugs into a standard SFP cage that supports the INF-8074i MSA and provides a single +3.3 V supply.

Can I link this 40 km transceiver with an older 10 km 1000BASE-LX module on the same single-mode fibre?

Yes, both use 1310 nm wavelength and duplex LC connectors, so they will interoperate provided the link budget covers the shorter 10 km distance.

How do I verify the link is healthy after installing the SFP?

Use the 2-wire SFF-8472 interface to read real-time diagnostics such as optical power, temperature and voltage from the switch management console.
