CBO transceiver SFM40G-SR4-BO QSFP+ 40G 850nm BlueOptics

The CBO Transceiver SFM40G-SR4-BO QSFP+ 40G 850nm BlueOptics is a compact optical module designed for 40 Gigabit Ethernet connections over multimode fiber. It operates at a wavelength of 850 nm and supports short-reach SR4 links, enabling high-density 40G connectivity in data centers, aggregation switches, and high-performance rack environments. The module is hot-pluggable and intended for use where reliable, low-latency links and straightforward installation are required.

Advantages

The transceiver offers a small form-factor QSFP+ design that maximizes port density while maintaining compatibility with standard 40G SR4 interfaces. Its 850 nm multimode operation is optimized for short-range fiber trunks and parallel multimode cabling. The hot-pluggable nature simplifies field replacement and expansion without powering down equipment, and the module is engineered for consistent signal integrity and stable performance in rack and switch deployments.

How to use

Install the QSFP+ transceiver into a compatible QSFP+ port on a switch or network device until it seats securely. Connect the appropriate multimode fiber MPO/MTP cable assembly to the module, ensuring correct fiber polarity for SR4 links. After insertion, the host device should recognize the module and negotiate the 40G link automatically. For hot-swap replacement, remove the module by disengaging the latch and pulling it straight out, then insert the replacement without powering down the chassis.

Recommendations

Use factory-quality OM3 or OM4 multimode fiber and compliant MPO/MTP cabling to achieve specified reach and performance. Verify device compatibility with the switch vendor’s QSFP+ port specifications and monitor link status after installation. Handle the transceiver by its housing, protect the connectors with dust caps when not in use, and store modules in anti-static packaging to prevent contamination and electrostatic damage.
