Modulo transceiver SFP BlueOptics SFP-7-CM-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-7-CM-BO is a fiber optic SFP transceiver module designed for single-mode links with a nominal data rate of 1250 Mbit/s and an operating wavelength of 1310 nm. The module has a metal housing, accepts a 3.3 V supply, and weighs approximately 3 g. It implements an LC duplex optical interface and supports long-reach transmission over single-mode fiber up to around 40 km for standard 1000BASE-LH applications. The transceiver is compatible with MSA-compliant SFP ports and is suitable for installation in switches, routers and other network equipment that accept SFP 1000BASE-LH modules.

Advantages

The module offers a compact metal construction for mechanical stability and heat dissipation, low power operation at 3.3 V, and a light weight that simplifies handling and installation. By using a 1310 nm optical wavelength and an LC duplex interface, it supports simultaneous transmit and receive channels for bidirectional fiber links. The SFP form factor provides hot-pluggable convenience and broad compatibility with equipment that follows SFP/1000BASE-LH MSA standards.

How to use

Install the SFP transceiver into an empty SFP slot of a compatible switch, router or media converter while the host device is powered according to the manufacturer's hot-plug guidelines. Connect LC duplex single-mode fiber patch cords to the module’s TX and RX ports, ensuring correct orientation for transmit and receive fibers. Verify link status on the host device and configure the interface for 1000BASE-LH or auto-negotiation as required by your network setup. If available, enable Digital Diagnostics Monitoring (DDM/DOM) in the host to read supply voltage, temperature and optical power metrics.

Recommendations

Use high-quality single-mode LC duplex patch cords and observe fiber handling best practices (avoid tight bends, keep connectors clean) to achieve the specified range and performance. Confirm that the target equipment supports SFP 1000BASE-LH modules and DDM/DOM if you intend to use diagnostic features. For long installations, test end-to-end link budget to ensure margin for connectors and splices.
