SFP transceiver module BlueOptics 1442340G1-BO 1250 Mbit/s 1310 nm

The BlueOptics 1442340G1-BO SFP transceiver module is designed for single‑mode fiber optic networks and supports a maximum data transfer rate of 1250 Mbit/s at a wavelength of 1310 nm. Housed in a compact, silver enclosure and weighing only 20 g, the module follows MSA SFP form‑factor standards and provides long MTBF values for stable operation in switches, routers and other network equipment that accept SFP modules.

Advantages

This SFP transceiver offers compatibility with a wide range of networking platforms that support 1000BASE‑LH optics, enabling up to 1.25 Gbit/s optical links over long distances when used with single‑mode fiber. The module is RoHS compliant, lightweight and manufactured using industry‑grade optical and electronic components to deliver extended operational lifetime and consistent signal quality. Digital diagnostic monitoring is supported where the host hardware implements DDM/DOM, allowing remote monitoring of key optical and electrical parameters.

Suitable for

• Gigabit Ethernet uplinks and inter‑switch links over single‑mode fiber
• Fiber Channel over Ethernet (FCoE) and SDH/SONET applications requiring 1.25 Gbit/s
• Replacement or upgrade of SFP 1000BASE‑LH ports in network switches, routers and storage systems
• Long‑reach optical links up to tens of kilometres when used with appropriate single‑mode fiber and connectors

Key specifications

• Interface type: SFP (small form‑factor pluggable)
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Operating wavelength (transmit/receive): 1310 nm
• Connector type: LC Duplex (for single‑mode fiber)
• Compliance: RoHS
• Weight: 0.02 kg
• Typical operational lifetime / MTBF: approximately 1,000,000 hours

How to use

Install the BlueOptics 1442340G1-BO by inserting the SFP module into a compatible SFP slot on your network device until it latches. Connect LC duplex single‑mode fiber patch cables to the module ensuring correct transmit/receive orientation. Configure the host device for the appropriate optical interface and confirm link status through the device management interface. If the host supports DDM/DOM, enable and monitor diagnostic parameters for voltage, laser bias current, transmit/receive power and module temperature to assist with maintenance and troubleshooting.

Recommendations

Use certified single‑mode LC duplex patch cords and follow vendor guidelines for cable routing and bend radius to achieve specified link distance and signal quality. Verify DDM/DOM support on your host device before relying on remote diagnostics. Store and handle the transceiver in a clean, ESD‑safe environment and keep protective dust caps on unused fiber connectors.
