SFP transceiver module BlueOptics SFP-3211-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-3211-BO is an SFP fiber optic transceiver module engineered for 1250 Mbit/s data transmission using a 1310 nm wavelength. Housed in a compact metal enclosure and operating from a 3.3 V supply, the module supports single-mode fiber links and features an LC duplex optical interface. The transceiver is suitable for standard 1000BASE-LX style applications, delivers duplex transmit and receive channels on separate fibers, and weighs approximately 20 g, making it easy to install in compatible SFP ports.

Advantages

This SFP module combines a metal housing for mechanical stability with a small form factor that fits standard SFP slots. It supports up to 1.25 Gbit/s throughput over a 1310 nm optical wavelength and is designed for single-mode fiber links. Built to industry MSA form-factor standards, the unit provides predictable electrical and optical characteristics and is compatible with hardware that accepts standard SFP 1000BASE-LX transceivers. Low power operation at 3.3 V and a lightweight design simplify deployment in switches, routers and other network equipment.

Suitable for

• Gigabit Ethernet links (1000BASE-LX) over single-mode fiber
• Fibre Channel over Ethernet and other 1.25 Gbit/s optical applications
• Interconnecting switches, routers, storage systems and media converters

Key specifications

• Interface type: SFP small form-factor pluggable
• Wavelength: 1310 nm
• Maximum data rate: 1250 Mbit/s (1.25 Gbit/s)
• Fiber type: single-mode fiber (LC duplex)
• Operating voltage: 3.3 V
• Housing: metal enclosure
• Weight: approx. 20 g

How to use

Install the BlueOptics SFP-3211-BO by inserting the transceiver into a compatible SFP slot until it latches. Connect an LC duplex single-mode patch cable: one fiber for transmit (TX) and the other for receive (RX). Ensure the host device supports 1000BASE-LX or SFP modules with the same electrical and optical characteristics; enable the appropriate port settings on the switch or router. Power is supplied through the host interface at 3.3 V, so no external power connection is required. For diagnostics, use the host equipment management interface or an optical monitoring tool if the platform supports DDM/DOM functions.

Usage recommendations

Use single-mode LC duplex patch cords and keep connectors clean to maintain signal quality. Verify compatibility and DDM/DOM support with your network hardware before deployment. For long-term reliability, install the module in well-ventilated equipment, avoid excessive bending of fiber cables, and follow vendor guidelines for hot-plugging SFP transceivers.
