Módulo transceptor SFP BlueOptics SFP-1G-SX-QN-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-1G-SX-QN-BO is an SFP fiber optic transceiver module designed for 1.25 Gbit/s (1250 Mbit/s) data links over multimode fiber at an 850 nm wavelength. Housed in a metal casing and powered from a 3.3 V supply, the compact module (approx. 3 g) provides bidirectional optical transmit and receive channels via an LC duplex connector following MSA standards. It supports 1000Base-SX applications and is intended as a compatible transceiver for systems that accept the same form factor and protocol.

Advantages

The module offers a standardized SFP interface that enables hot-pluggable installation and interoperability with a wide range of switches, routers and storage devices that support 1000Base-SX optics. Its metal housing provides EMI shielding and mechanical durability, while the compact, lightweight design simplifies deployment in dense equipment racks. Built to MSA specifications, the transceiver supports multimode fiber links to typical distances for 850 nm optics and is suitable for Ethernet and related high-speed protocols up to 1.25 Gbit/s.

Suitable for

• 1 Gbit/s Ethernet links over multimode fiber (1000Base-SX)
• Interconnecting switches, routers and NAS or SAN storage systems
• Short- to medium-range optical links within buildings and campus networks
• Networks requiring hot-pluggable, standard SFP modules with LC duplex connectors

How to use

Install the BlueOptics SFP-1G-SX-QN-BO by inserting it into a compatible SFP slot on your network device until it latches; ensure the device is powered and that the slot supports 1000Base-SX optics. Terminate the optical link with LC duplex multimode patch cords and observe correct fiber polarity. Configure the network port on the host device to the appropriate speed and duplex settings if required by the equipment. For remote monitoring of optical parameters, enable Digital Diagnostics Monitoring (DDM/DOM) on hardware that supports SFF-8472 to read supply voltage, laser bias current, output and input optical power, and module temperature.

Recommendations

Use high-quality multimode fiber patch cords and maintain clean LC connectors to achieve optimal transmit/receive performance. Verify device compatibility and DDM support in the host hardware before deployment. For best results in short to medium reach applications, follow the multimode fiber specifications and maximum distance recommendations for 850 nm 1000Base-SX links.
