## Summary description

The BlueOptics SFP-GE40KM-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It operates at a wavelength of 1310 nm and is designed for reliable network connections. The module is housed in a durable metal casing and operates at an input voltage of 3.3 V. Weighing only 3 g, it is lightweight and easy to install, making it suitable for various networking applications.

## Long description

The BlueOptics SFP-GE40KM-BO is a single-mode fiber optic SFP transceiver module designed for 1.25 Gbit/s (1250 Mbit/s) Ethernet links over long distances. It transmits and receives at 1310 nm and supports optical links up to 40,000 m. Housed in a durable silver metal casing and weighing approximately 3 g, the module is powered by a 3.3 V supply and fits standard SFP ports with LC duplex connections according to MSA guidelines.
Advantages
This transceiver provides long-reach single-mode operation with a maximum transfer distance of up to 40 km while maintaining a compact, lightweight metal enclosure that simplifies installation. Compliance with SFP/LC interface standards ensures plug-and-play compatibility in systems that accept standard 1000BASE-LH SFP modules. The module’s form factor and low power requirement (3.3 V) make it suitable for dense rack deployments and network equipment with constrained power budgets.
Suitable for
Long-distance single-mode Ethernet links (up to 40 km)
Switch-to-switch and router-to-router fiber connections
Server and storage network uplinks requiring 1.25 Gbit/s optical interfaces
Optical backbone segments in enterprise and campus networks
Key specifications
Data rate: 1250 Mbit/s (1.25 Gbit/s)
Wavelength: 1310 nm (Tx/Rx)
Maximum reach: 40,000 m (40 km) over single-mode fiber
Connector type: LC duplex (SFP form factor)
Operating voltage: 3.3 V
Product colour and housing: silver metal casing
Weight: approx. 0.003 kg
How to use
Insert the SFP transceiver into any compatible SFP port on switches, routers or other network equipment while the host device is powered down or following the vendor’s hot-swap guidance. Connect an LC duplex single-mode fiber patch cable, observing correct Tx/Rx orientation. After insertion, verify link status on the host device and configure the interface for 1000BASE-LH or the corresponding 1.25 Gbit/s protocol. Confirm that connected equipment supports the module’s optical parameters and any digital diagnostic monitoring (DDM/DOM) features if monitoring is required.
Usage recommendations
Use high-quality single-mode LC patch cords and clean connector endfaces before mating. Ensure both ends of the link use compatible transceivers and that device firmware supports SFP modules with the stated optical characteristics. For critical links, enable and monitor DDM/DOM (if supported by the host) to observe supply voltage, laser bias, output and receive power and temperature for preventive maintenance.
