Product information

Description

The BlueOptics SFP-21B-BO 40000 m Aluminium is a single-mode fiber optic transceiver module with an SFP interface, designed for optical data links up to 40,000 meters. Constructed with an aluminum housing and weighing approximately 20 g, this transceiver supports bidirectional transmission using separate transmitter and receiver wavelengths over LC simplex connector and complies with MSA form-factor standards. It is intended for integration into network hardware that supports SFP modules and is suitable for high-speed applications that require a stable single-mode fiber connection.

Advantages

The module provides long-reach single-mode transmission up to 40 km while remaining compact and lightweight. Its aluminum enclosure offers mechanical durability and thermal dissipation. Conformance to SFP/MSA form factors and the LC simplex connector ensures broad interoperability with compatible switches, routers and storage systems. Digital diagnostics (DDM/DOM) support enables remote monitoring of key parameters such as supply voltage, laser bias current, optical output and input power, and temperature for simplified fault analysis and maintenance.

Suitable for

  • Long-distance single-mode Ethernet links (up to 40 km)
  • Interconnection of switches and routers in campus and metro networks
  • Fiber uplinks to distribution frames and patch panels
  • Fiber channel or SDH/SONET interfaces requiring SFP modules

Key specifications

  • Interface type: SFP (MSA form-factor)
  • Transmission distance: up to 40,000 m (single-mode fiber)
  • Connector: LC simplex
  • Wavelengths: typical bidirectional pair (separate transmit and receive wavelengths for single-fiber operation)
  • Housing material: aluminium
  • Weight: approx. 20 g
  • Digital diagnostics: DDM/DOM (per SFF-8472) for real-time monitoring
  • Supported protocols: Ethernet and other optical high-speed protocols up to gigabit class

How to use

Insert the SFP module into an available SFP port on a compatible switch, router or other network device while the host device is powered according to the vendor’s instructions. Connect an appropriate single-mode LC patch cord to the LC simplex connector and ensure correct fiber polarity for bidirectional single-fiber operation. Verify link synchronization and protocol settings on both endpoints. If the host device supports DDM/DOM, monitor the module’s diagnostic parameters from the management interface to confirm optical power, temperature and supply values.

Usage recommendations

Use high-quality single-mode fiber and compatible LC patch cords, avoid sharp bends and maintain proper fiber polarity. Confirm device compatibility with the host vendor’s hardware and enable DDM/DOM monitoring when available to aid in preventive maintenance and fault diagnosis.
