SFP-transceiver BlueOptics USFP-03/S1-D-R-BO 155 Mbit/s 1310 nm

The BlueOptics USFP-03/S1-D-R-BO is a small form-factor fiber optic SFP transceiver designed for single-mode links with a nominal wavelength of 1310 nm and a maximum data transfer rate of 155 Mbit/s. Housed in a metal casing and weighing approximately 20 g, this module uses an LC duplex connector and supports optical transmission distances up to 20 km. It conforms to MSA SFP mechanical form factors and is intended for use in compatible network equipment that accepts 100BASE-LX transceivers.

Advantages

The transceiver’s metal housing provides mechanical robustness and reliable thermal dissipation while the LC duplex interface enables simultaneous transmit and receive channels on single-mode fiber. Support for a 1310 nm wavelength and a 20 km range makes the module suitable for metropolitan and campus fiber runs. The module is designed to meet MSA standards for form factor and interface compatibility and includes standard diagnostics support when used in equipment that exposes Digital Diagnostics Monitoring (DDM/DOM).

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP port on your switch, router or media converter while the host device is powered down or following the device vendor’s hot-plug guidelines. Connect LC duplex single-mode patch cords ensuring correct transmit-to-receive alignment on each end. If your host supports Digital Diagnostics Monitoring (DDM/DOM), enable or read the diagnostics through the device management interface to monitor parameters such as supply voltage, laser bias current, optical output and received power, and temperature. Configure the connected interfaces on network devices according to your network design and speed/duplex settings required for 100BASE-LX links.

Recommendations

Use single-mode LC duplex fiber patch cords of appropriate quality and low insertion loss, ensure cleanliness of connectors before mating, and verify compatibility with your host hardware. For reliable long-term operation, follow vendor guidelines on handling electrostatic-sensitive devices and operate the transceiver within recommended temperature and power ranges. When monitoring link health, rely on DDM/DOM data if available and keep spare modules for critical paths to minimize downtime.
