SFP transceiver module BlueOptics 321-2313-BO Copper 1250 Mbit/s

The BlueOptics 321-2313-BO Copper SFP transceiver module provides a compact, hot-pluggable interface for short-range copper Ethernet links. Designed in the SFP form factor, this module supports a maximum data transfer rate of 1250 Mbit/s over a single RJ-45 port and is suitable for integrating 1.25 Gigabit Ethernet connections into compatible network equipment. The module is finished in silver, weighs approximately 20 g, and offers an MTBF of 1,000,000 hours to support reliable network operation.

Advantages

This SFP transceiver delivers a small physical footprint and hot-pluggable convenience, enabling easy upgrades or replacements without powering down equipment. With a maximum transfer rate of 1250 Mbit/s and support for standard RJ-45 copper cabling, it provides straightforward connectivity for short-distance links up to 100 m. The specified MTBF indicates longevity suitable for continuous operation in typical network environments.

Suitable for

• Connecting switches, routers, and media converters via copper Ethernet
• Short-distance 1.25 Gigabit Ethernet links within racks or between adjacent rooms
• Field replacements and on-site upgrades requiring hot-pluggable modules
• Environments where a compact SFP form factor is required

How to use

Insert the BlueOptics SFP transceiver into a compatible SFP slot on a switch, router or media converter while the device is powered according to the host equipment manual where hot-plugging is supported. Connect a standard Cat5e/Cat6 copper Ethernet cable to the RJ-45 port and secure connections at both ends. Configure the host device network settings as required for the intended link speed and duplex; most equipment will auto-negotiate the connection. Follow the network equipment manufacturer’s guidance for handling and ESD precautions.

Recommendations

Use high-quality twisted-pair copper cabling and keep link lengths within 100 m to maintain signal integrity. Verify compatibility with the host device’s SFP interface and firmware, and replace the module if physical damage or persistent link issues occur.
