Fiber optic transceiver CBO QSFP28-100G-SR4 100G multimode short-range

The BlueOptics CBO QSFP28-100G-SR4 100G multimode short-range transceiver is a compact QSFP28 module offering four independent 25G lanes for short-distance multimode fiber connections. Designed for high-density network environments, the module enables 100 Gigabit Ethernet links between switches, servers and aggregation devices. It supports hot-plug installation and conforms to standard QSFP28 mechanical and electrical interfaces for straightforward integration into existing data center and enterprise networking equipment.

Advantages

This QSFP28 transceiver delivers four-channel 25G transmission over multimode fiber, enabling cost-effective short-range 100G links with a small form factor. Its compliance with QSFP28 specifications ensures compatibility with common switch and server ports, while hot-plug capability reduces maintenance downtime. The module is suitable for high-density installations where space and power efficiency are important.

Suitable for

• 100 Gigabit Ethernet connections in data centers and server rooms
• Short-range multimode fiber links between switches and aggregation equipment
• High-density patch panels and spine-leaf network architectures
• Interconnects between top-of-rack switches and storage or compute racks

Key specifications

• Form factor: QSFP28 with four 25G lanes
• Data rate: 100 Gbps aggregate
• Optical type: Multimode, short-range
• Connector: MPO/MTP multi-fiber interface
• Hot-pluggable design
• Typical use: Short-reach links within data centers

How to use

Insert the transceiver into a compatible QSFP28 port on a switch, server or transceiver cage while the host device is powered on, taking care to align the module and connector correctly. Use a multimode MPO/MTP patch cord to connect to the corresponding fiber panel or module. Verify link status and speed via the host device management interface, and consult the network equipment documentation for any port configuration required for 100G operation.

Recommendations

For reliable short-range performance, use OM3 or OM4 multimode fiber with MPO/MTP connectors and maintain proper fiber handling and bend-radius limits. Confirm transceiver compatibility with the host device vendor and update firmware or port settings as needed to enable full 100G throughput.
