Product information

Description

The BlueOptics SFP-21BH-BO 1250 Mbit/s is a compact fiber optic SFP transceiver module designed for single-mode long‑reach applications. Housed in metal and weighing just 3 g, the module supports a maximum data transfer rate of 1250 Mbit/s and an optical reach up to 40 km. It uses an LC simplex interface and operates at a 3.3 V input supply, providing a standards‑compliant option for Ethernet, Fibre Channel over Ethernet or SDH/SONET links in switches, routers and other network equipment that accept SFP form factor modules.

Advantages

The module offers industry-standard compatibility with MSA-compliant SFP ports and is built with high-quality optical and electronic components to ensure long operational lifetime and stable link performance. Compact metal housing provides mechanical robustness and thermal stability, while the low weight makes it suitable for dense port installations. Support for digital diagnostics (DDM/DOM) enables remote monitoring of supply voltage, laser bias current, optical output and input power plus temperature when the host device supports these features.

Suitable for

  • Long-distance single-mode fiber links up to 40 km
  • Gigabit Ethernet and 1.25 Gbps optical interfaces
  • Interconnection of switches, routers and storage systems
  • Deployments that require DDM/DOM monitoring in compatible hardware

Key specifications

  • Data rate: up to 1250 Mbit/s
  • Maximum optical reach: 40000 m (single-mode)
  • Connector type: LC simplex (SFP form factor)
  • Operating voltage: 3.3 V
  • Housing material and color: metal, silver
  • Weight: approximately 0.003 kg

How to use

Insert the SFP transceiver into a compatible SFP slot of the network device until it latches; connect an appropriate single‑mode LC patch cable to the LC simplex port. Ensure the host device supports the intended protocol (Ethernet, Fibre Channel over Ethernet or SDH/SONET) and verify that the device accepts third‑party SFP modules if required. If digital diagnostics are required, confirm that the host supports DDM/DOM and monitor the transceiver parameters through the device management interface. Follow standard electrostatic discharge (ESD) precautions when handling the module.

Usage recommendations

For optimal link performance use single‑mode fiber and quality LC patch cords, observe correct transmit/receive pairing for BX transceivers, and verify wavelength pairing if deploying asymmetric wavelength solutions. Keep firmware and device drivers up to date and verify DDM/DOM readings during commissioning to ensure stable operation.
