QSFP Transceiver Module BlueOptics QSFP-40G-LR4-20-CI-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-CI-BO is a QSFP fiber optic transceiver module engineered for 40 Gbit/s data links. Designed for use in data centers and enterprise networks, this compact module supports high-speed optical transmission over single-mode fiber with LC connectors. Its lightweight construction (approximately 40 g) and QSFP form factor make it suitable for dense port deployments where space and power efficiency are important.

Advantages

This QSFP transceiver provides a stable 40 Gbit/s throughput and supports long-reach transmission up to 20 km over single-mode fiber. The LC fiber connector interface enables compatibility with standard duplex fiber patching, while the QSFP form factor ensures compatibility with a wide range of switches, routers and network appliances that accept QSFP modules. The module’s compact size and low weight contribute to easy installation and minimal mechanical strain on cages and ports.

Key specifications

How to use

Install the transceiver into a QSFP-compatible port on a switch, router or optical transceiver cage, ensuring correct orientation and a secure mechanical latch. Connect LC-terminated single-mode fiber patch cables to the module’s LC ports, observing transmit/receive pairing. Verify link status and speeds via the host device interface or management software and ensure optical power levels and link distances are within supported ranges.

Recommendations

Handle the module with care to avoid contamination of optical interfaces; keep dust caps on unused connectors and follow standard ESD precautions during installation. For reliable long-reach links, use certified single-mode fiber and maintain clean LC connectors to minimize insertion loss.
