SFP-lähetin-vastaanotinmoduuli BlueOptics SFP-1G-SX-QL-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-1G-SX-QL-BO is a compact fiber optic SFP transceiver module designed for 1000Base-SX networks. It supports a maximum data transfer rate of 1250 Mbit/s and operates at an 850 nm wavelength over multimode fiber. The module has a metal housing for mechanical durability, uses a standard SFP interface with an LC duplex connector and requires a 3.3 V supply. Weighing approximately 3 g, it is suitable for space-constrained networking equipment and straightforward to install according to MSA SFP specifications.

Advantages

The module provides compatibility with QLogic-based platforms by following MSA standards, enabling use in switches, routers, storage systems and similar hardware that accept QLogic 1000Base-SX SFP transceivers. Built with industry-grade components and a metal enclosure, it offers robust signal transmission over multimode fiber with low susceptibility to electromagnetic interference. Integrated digital diagnostics (DDM/DOM) support allows real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when supported by the host device.

Suitable for

• Gigabit Ethernet links over multimode fiber (1000Base-SX)
• Data center uplinks and switch-to-switch connections
• Storage area networks and Fibre Channel over Ethernet applications
• Short- to medium-distance optical links up to multimode fiber limits (typical up to several hundred meters)

Key specifications

• Interface type: SFP (LC duplex connector)
• Nominal data rate: up to 1250 Mbit/s
• Operating wavelength: 850 nm (transmit and receive)
• Fiber type: multimode fiber (MMF), 1000Base-SX standard
• Supply voltage: 3.3 V
• Construction: metal housing, silver colour
• Weight: approx. 0.003 kg
• Supports Digital Diagnostics Monitoring (DDM/DOM) per SFF-8472 when host supports the feature

How to use

Install the BlueOptics SFP-1G-SX-QL-BO by inserting it into a compatible SFP port on the host device until it latches according to the hardware vendor’s instructions. Connect an LC duplex multimode patch cable between corresponding transceivers, ensuring proper transmit/receive orientation. Verify that the host device recognizes the transceiver and, if applicable, enable or read out DDM/DOM parameters to monitor operating conditions. Follow the equipment manufacturer’s hot-plug and ESD handling procedures during installation and removal.

Recommendations

For optimal performance, use high-quality multimode fiber and LC duplex patch cords, keep fiber connectors clean, and ensure the host device firmware supports third-party SFP modules and DDM/DOM if you require diagnostic monitoring. Observe the recommended multimode fiber distance limits for 1000Base-SX to maintain link reliability.
