Vláknový transceiver CBO QSFP-40G-LR4-CI-BO 40 Gbit/s, Singlemode, až do 10.000 m

The BlueOptics QSFP-40G-LR4-CI-BO is a fiber optic transceiver module that supports 40 Gbit/s aggregate throughput over single-mode fiber. Engineered for long-reach links, it implements four-channel LR4 operation to carry 40 Gigabit Ethernet or equivalent high-speed signals up to 10,000 m. The module uses the QSFP form factor to provide a compact, hot-pluggable interface suitable for switches, routers and optical line systems requiring high-density ports and extended single-mode reach.

Advantages

This transceiver offers long-distance single-mode performance with a reach of up to 10,000 m while maintaining a compact QSFP package that supports four optical lanes in a single connector. Its LR4 multi-wavelength design enables reliable 40 Gbit/s transmission over long-haul and metro links, reducing the need for intermediate repeaters or conversions. The module is compatible with systems that accept standard QSFP optics and is intended for robust operation in data center interconnects and carrier networks where sustained throughput and link stability are required.

Suitable for

• 40 Gigabit Ethernet backbone links between data centers
• Long-reach metro and carrier transport networks
• High-density switch and router ports requiring QSFP connectivity
• Optical aggregation and interconnect links in service provider infrastructure

Key specifications

• Aggregate data rate: 40 Gbit/s over four channels
• Optical mode: single-mode fiber (SMF)
• Maximum reach: up to 10,000 meters on single-mode fiber
• Operating wavelengths: LR4 multi-wavelength transmission (four-channel)
• Form factor: QSFP (Quad Small Form-factor Pluggable), hot-pluggable
• Typical application: 40 Gigabit Ethernet and equivalent high-speed optical links

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or optical interface card while the host device is powered according to the vendor’s hot-plug guidelines. Connect single-mode fiber optical cables with appropriate LC or breakout connectors to the transceiver’s port, ensuring correct polarity and clean fiber endfaces. After insertion and link establishment, verify the link status and optical parameters via the host device management interface. Follow system vendor instructions for firmware compatibility and supported transceiver lists to ensure proper operation.

Recommendations

Use single-mode fiber with suitable launch power and receiver sensitivity margins for long-reach links; perform end-to-end testing of optical loss and dispersion for runs approaching the 10,000 m limit. Keep transceiver contacts and fiber connectors clean, observe ESD precautions during handling, and consult the host equipment documentation for supported optical modules and transceiver settings.
