Fiber optic transceiver module BlueOptics CPAC-TR-40LR-QSFP 10KM Aluminium

The BlueOptics CPAC-TR-40LR-QSFP 10KM Aluminium is a fiber optic transceiver module designed for high-speed single-mode links up to 10 km. Featuring a QSFP interface and an aluminium housing, this compact 20 g module implements 40GBASE-LR4 optical transmission with LC Duplex connectivity and is intended for use in network equipment that supports QSFP optical ports. The module supports standard optical signalling across CWDM lanes and provides a compact, durable form factor for high-density installations.

Advantages

The module provides 40 Gbit/s optical bandwidth over distances up to 10 kilometres on single-mode fiber while remaining lightweight and robust due to its aluminium casing. Compliance with common QSFP and MSA form-factor expectations ensures interoperability with devices that accept QSFP transceivers. Built-in support for CWDM lanes enables four-channel 40GBASE-LR4 operation using LC Duplex connectors, and the compact design facilitates use in high-density switches, routers and storage systems.

Key specifications

How to use

Install the transceiver into a compatible QSFP port on your switch, router or other network equipment while the device is powered down or following the vendor's hot-swap guidance. Connect LC Duplex single-mode fiber patch cords to the module's LC receptacles, observing transmit/receive orientation. Confirm that the host device recognises the transceiver and that interface parameters (speed, lane mapping and DDM/DOM support) match the equipment configuration. Monitor link status and optical levels via the host system; enable Digital Diagnostics Monitoring if supported by both the transceiver and the host to read real-time parameters such as optical power and temperature.

Recommendations

Use single-mode LC Duplex patch cords of appropriate attenuation and length, keep fiber connectors clean, and verify DDM/DOM support on the host to enable remote diagnostics. For best interoperability, use the module in hardware platforms that explicitly support QSFP 40GBASE-LR4 transceivers and follow vendor guidelines for firmware or compatibility settings.
