## Summary description

The BlueOptics SFP-21BED-BO is a fiber optic transceiver module designed for high-speed data transfer at 1250 Mbit/s. It features a metal housing for durability and operates at an input voltage of 3.3 V. This SFP transceiver is ideal for network applications requiring reliable and efficient data transmission.

## Long description

The BlueOptics SFP-21BED-BO is a single‑port SFP fiber optic transceiver module engineered for 1250 Mbit/s data transmission over single‑mode fiber. Featuring a compact metal housing and a 3.3 V supply requirement, this transceiver follows MSA SFP form‑factor standards and provides an LC simplex interface for optical connection. The module implements a bidirectional 1000BASE‑BX‑D scheme with transmit and receive wavelengths optimized for long‑reach links and supports common high‑speed network protocols including Ethernet and Fibre Channel over Ethernet.
Advantages
The module delivers stable optical connectivity with a metal enclosure that enhances durability and thermal performance. Compliance with MSA SFF specifications ensures broad compatibility with hardware platforms that support the equivalent RAD SFP‑21BED transceiver. Built‑in digital diagnostic monitoring (DDM/DOM) capability enables real‑time reporting of supply voltage, laser bias current, transmit output power, received input power and temperature for simplified troubleshooting and maintenance. Designed for long operational life, the transceiver uses industry‑grade components to support continuous operation in demanding network environments.
Suitable for
Long‑reach single‑mode links in switches and routers
Data center interconnects and storage networking
SDH/SONET and enterprise Ethernet up to 1.25 Gbit/s
Optical backbone connections with LC simplex connectors
Key specifications
Interface type: SFP (MSA compliant)
Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
Connector: LC simplex
Optical mode: Single‑mode fiber
Transmit/receive: Bidirectional (separate TX and RX wavelengths)
Operating voltage: 3.3 V
Product colour: Silver (metal housing)
Digital diagnostic monitoring: DDM / DOM (SFF‑8472 compatible)
Typical reach: long‑reach operation suitable for links up to tens of kilometers (per 1000BASE‑BX‑D application)
How to use
Insert the SFP‑21BED‑BO transceiver into an SFP slot on a compatible switch, router or optical device while the host equipment is powered according to the vendor’s instructions. Connect an LC simplex single‑mode patch cord to the module’s LC connector; ensure TX of one end is connected to RX of the remote end and vice versa for bidirectional operation. Verify that the host device recognizes the module and that the link status indicators report an active connection. If supported by the host, enable or read digital diagnostic parameters to monitor operating conditions remotely.
Usage recommendations
Use factory‑quality single‑mode fiber patch cords and, where possible, a matching BlueOptics patch panel or transceiver at the far end for optimal range and signal quality. Confirm DDM/DOM support in the host device before relying on diagnostic readouts. Install and remove the module following ESD precautions and the host manufacturer’s guidelines to maintain long‑term reliability.
