SFP transceiver module BlueOptics SRX-SFP-1GE-LH-ET-BO Fiber optic 40000 m

The BlueOptics SRX-SFP-1GE-LH-ET-BO is a single‑mode fiber SFP transceiver module designed for long‑reach gigabit links up to 40,000 meters. Housed in aluminium and weighing 20 g, the module follows MSA SFP form‑factor conventions and uses an LC duplex connector for simultaneous transmit and receive over separate fibers at 1310 nm. It supports 1000BASE‑LH optical signalling and is suitable for typical networking hardware that accepts compatible 1 G SFP modules.

Advantages

This transceiver provides long‑distance single‑mode optical connectivity with compact SFP sizing and low weight, enabling space‑efficient installation in switches, routers and other networking devices. Built to MSA compatibility, it offers optical transmit and receive at 1310 nm via LC duplex interface and is assembled with components intended for robust lifetime and stable performance. The aluminium housing gives mechanical protection while helping with thermal dissipation in rack and chassis environments.

Suitable for

• Long‑reach gigabit Ethernet links over single‑mode fiber (up to 40 km)
• Interconnects between switches, routers and network appliances
• Data centre patching and campus backbone links
• Replacement or upgrade of compatible 1 G SFP ports

Key specifications

• Interface type: SFP (MSA compatible)
• Optical standard: 1000BASE‑LH (1 Gbps)
• Wavelength: 1310 nm (Tx and Rx)
• Connector: LC duplex
• Transmission medium: Single‑mode fiber
• Maximum reach: 40,000 m (40 km)

How to use

Insert the SFP transceiver into a compatible SFP port until it seats securely and engage any latch or retention mechanism provided by the host device. Connect an LC duplex single‑mode patch cable to the transceiver, ensuring correct orientation for transmit and receive fibres. Configure the host device network interface for 1000 Mbps operation if required and verify link status before placing the link into production. Follow your hardware vendor instructions for hot‑swap and power management when installing or removing modules.

Recommendations

When deploying long‑reach fiber links, use quality single‑mode patch cords and verify connector cleanliness to maintain optical performance. Confirm device compatibility with MSA‑compliant SFP modules and, if available, enable digital diagnostics (DDM/DOM) in your host system to monitor optical parameters and support remote troubleshooting.
