Fiber optic transceiver CBO QSFP-100G-SR4 100G multimode short-reach

The BlueOptics CBO QSFP-100G-SR4 is a QSFP28 fiber optic transceiver designed for 100 Gbps multimode short-reach links. It enables parallel multimode fiber connections for high-bandwidth, low-latency transmission between switches, servers and aggregation equipment in data center and enterprise network environments. The module conforms to QSFP28 form factor dimensions and supports short-reach multimode fiber distances suitable for intra-rack and intra-data-center interconnects.

Advantages

This transceiver offers 100 Gbps aggregate bandwidth using a four-lane parallel multimode interface, providing reliable short-range connectivity with low power consumption and compact QSFP28 packaging. It is compatible with standard multimode optical infrastructure and hot-pluggable for easy installation without system downtime. The device is engineered to meet industry signal and thermal profiles for stable operation in dense networking environments.

Suitable for

• Short-reach links within data centers between switches and server racks
• High-speed aggregation and spine-leaf network interconnects
• Multimode fiber backbone segments and patching within campus or enterprise facilities
• Upgrading existing multimode infrastructures to 100 Gbps capacity

Key specifications

• Form factor: QSFP28 compatible
• Data rate: 100 Gbps aggregate (4 x 25 G lanes)
• Media type: Multimode fiber (parallel MPO/MTP connector)
• Reach: Short-reach distances on multimode fiber (designed for intra-rack and intra-data-center links)
• Wavelength: Multimode VCSEL-based transmission across parallel lanes
• Power consumption: Low-power QSFP28 module class

• Operating environment: Designed for standard data center temperature ranges

How to use

Insert the QSFP28 transceiver into a compatible QSFP port on the switch or server line card while the host device is powered on to take advantage of hot-pluggable operation. Connect a parallel multimode MPO/MTP patch cable between transceivers on the two endpoints, ensuring correct fiber polarity and clean connector end faces. Monitor link status via the host system interface and verify correct lane alignment and optical power levels according to the switch or transceiver diagnostics.

Recommendations

For reliable performance, use multimode fiber of appropriate OM grade (OM3/OM4) and maintain proper fiber cleaning and connector inspection procedures. Avoid exceeding specified data center temperature ranges and check compatibility with the host equipment’s supported QSFP28 transceiver profiles before deployment.
