Medený transceiver modul BlueOptics 378929-B21-BO 1250 Mbit/s SFP

The BlueOptics 378929-B21-BO Copper transceiver module is an SFP form-factor network transceiver designed for 1250 Mbit/s data links. It provides a compact, low-weight (20 g) solution in grey housing for standard SFP interfaces and supports short-range multimode connections using an 850 nm optical wavelength. The module is compatible with devices that accept SFP 1000Base-SX style transceivers and is intended for reliable network connectivity in switches, routers and other network hardware.

Advantages

The module supports a 1250 Mbit/s maximum data transfer rate and fits standard SFP slots, delivering a straightforward plug-and-play option for equipment that accepts 1000Base-SX transceivers. Its compact size and light weight simplify installation and reduce space usage in dense patch panels or chassis. Manufactured to MSA-compatible mechanical and electrical specifications, the transceiver provides predictable interoperability with compatible network hardware and consistent optical performance at the specified 850 nm wavelength.

Suitable for

• Upgrading or replacing SFP ports in switches and routers that support 1000Base-SX transceivers
• Multimode fiber links for LAN and campus networks
• Short-range Ethernet, Fibre Channel over Ethernet or SDH/SONET applications up to supported link distances
• Environments requiring compact, hot-pluggable transceivers for service and maintenance

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Maximum data transfer rate: 1250 Mbit/s
• Operating wavelength: 850 nm
• Product colour: Grey
• Weight: 0.02 kg
• Connector type: LC duplex (for multimode optical connections)

How to use

Install the transceiver into a compatible SFP slot on the network device while the device is powered according to the vendor instructions for hot-pluggable modules. Connect the LC duplex multimode patch cable to the transceiver’s optical interface and the corresponding port on the remote device, ensuring proper fiber polarity. Verify link status via the host device management interface and confirm that the host supports 1000Base-SX/1250 Mbit/s transceivers and, if required, Digital Diagnostics Monitoring (DDM)/DOM features for optical parameter readouts.

Recommendations

Use multimode fiber patch cords and appropriate LC duplex connections for optimal range and signal quality. Ensure the host device officially supports SFP 1000Base-SX modules and enable any required firmware settings for third-party transceivers. Store and handle the transceiver in a clean, electrostatically safe environment and avoid exposing optical interfaces to dust or contaminants.
