SFP transceiver module BlueOptics SFP-GE-LH70-SM1550-D-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-GE-LH70-SM1550-D-BO is a single-mode SFP transceiver module designed for long-distance fiber optic links. It supports data rates up to 1250 Mbit/s and operates at a wavelength of 1550 nm. The module is housed in a metal casing, runs on a 3.3 V supply and weighs approximately 3 g, offering a compact and lightweight option for network devices that accept SFP form-factor modules.

Advantages

This SFP transceiver provides reliable single-mode optical transmission over extended distances up to 80 km and uses a standardized LC Duplex interface for transmit and receive channels. Its metal housing ensures mechanical durability and EMI shielding, while the small size and 3.3 V operation make it compatible with a wide range of switches, routers and media converters that support SFP modules. The module's design follows common MSA form-factor conventions to simplify integration into existing optical network hardware.

Suitable for

• Long-distance Ethernet links up to 80 km over single-mode fiber
• Interconnects between switches, routers and media converters supporting SFP
• Fiber uplinks in campus, metro or branch networks
• Applications requiring a 1550 nm wavelength and 1.25 Gbit/s class throughput

Key specifications

• Maximum data transfer rate: 1250 Mbit/s
• Operating wavelength: 1550 nm
• Maximum transfer distance: 80,000 m (80 km) over single-mode fiber
• Connector type: LC Duplex (SFP form factor)
• Operating voltage: 3.3 V
• Weight: approx. 0.003 kg
• Housing: metal, silver colour

How to use

Install the BlueOptics SFP module into an SFP slot on a compatible switch, router or media converter while the host device is powered down or following the vendor's hot‑swap guidelines. Connect LC Duplex single-mode fiber patch cords with correct polarity to the transmit and receive ports. Configure the host interface according to the network device documentation so the link operates at the required protocol and speed. Verify link status and diagnostics through the host system once the module is seated and fibers are connected.

Recommendations

Use high-quality single-mode patch cords and clean connectors to achieve the specified 80 km reach. Confirm that the target hardware supports third-party SFP modules and, if available, enable Digital Diagnostics Monitoring (DDM/DOM) in the host device to monitor real-time parameters such as supply voltage, laser bias current, optical output/receive power and module temperature.
