Fiber optic cSFP transceiver BlueOptics CSFP-BX1490-40-D-BO 1250 Mbit/s silver metal housing

BlueOptics CSFP-BX1490-40-D-BO is a compact cSFP fiber optic transceiver in a silver metal housing designed for single-mode links. It supports a data rate up to 1250 Mbit/s and provides a hot-pluggable LC duplex interface for integration into switches, routers and other networking hardware. The module combines a 1310 nm transmitter and a 1490 nm receiver for bidirectional transmission over a single fibre and is rated for a long operational life with an MTBF of 1,000,000 hours while weighing approximately 20 g.

Advantages

The transceiver is MSA-compliant and compatible with equipment that accepts standard cSFP modules, enabling interoperable deployment across multiple vendor platforms. Its metal silver housing provides mechanical robustness and EMI resilience while the lightweight design simplifies installation. The module supports common optical applications up to 1250 Mbit/s and is suitable for distances typical of short- to mid-range single-mode links.

Key specifications

How to use

Insert the BlueOptics cSFP module into a compatible cSFP port while the host device is powered on or off, following the host manufacturer's guidance for hot-plugging. Connect LC duplex single-mode fiber patch cords ensuring correct TX↔RX alignment (transmitter to receiver) and secure the patch cords to avoid strain. Verify link status on the host device and confirm that the operating data rate of 1250 Mbit/s is negotiated or configured in the networking equipment. Use appropriate transceiver settings in the switch or router firmware if required for interoperability.

Recommendations

Ensure the host device supports the cSFP form factor and the specific bidirectional wavelength pairing. Use single-mode LC duplex patch cords and proper fiber management to maintain signal quality. If Digital Diagnostics Monitoring (DDM/DOM) is required, confirm that the host hardware supports DDM to access real-time parameters such as supply voltage, temperature, and optical power.
