Transceiver CBO OPT-0031 QSFP28 100G Fiber Optic module

The Transceiver CBO OPT-0031 QSFP28 100G Fiber Optic module is a compact high-speed optical interface designed for use in networking equipment. It supports a 100 Gbps aggregate data rate in a QSFP28 form factor and is compatible with systems that accept four 25 G lanes. The module is intended for installation in switches, routers and optical transceivers used in data center interconnects, aggregation layers and uplink ports.

Advantages

This QSFP28 100G module delivers a high-density 4-channel solution in a single small form factor, enabling efficient use of port space in racks and chassis. It provides stable 100 Gbit/s performance for long-distance optical links and is compatible with industry-standard QSFP28 interfaces. The design enables straightforward integration into existing networking hardware that supports 25G per lane operation, helping simplify upgrades from 10G/40G infrastructures.

Suitable for

• Data center uplinks and server aggregation
• Switch-to-switch optical links in enterprise networks
• Long-distance fiber connections between network sites
• High-density deployments requiring compact 100G ports

Key specifications

• Form factor: QSFP28 (four 25 G lanes, 100 G aggregate)
• Data rate: 100 Gbit/s
• Optical interface: multi-channel fiber (pluggable QSFP28)
• Application: short to long-reach optical links depending on transceiver variant and fiber type
• Compatibility: systems supporting QSFP28 and 25G per lane operation

How to use

Install the module by inserting it into a compatible QSFP28 port on the switch, router or optical transceiver chassis until it clicks into place. Connect appropriate fiber cables to the module’s optical ports, ensuring correct fiber type and polarity. Configure the network device to recognize the 100G interface and adjust link parameters if required by the equipment’s management software. Monitor link status through the device management interface to confirm proper operation.

Recommendations

Use factory-quality single-mode or multi-mode fiber as specified by the host device and the product variant. Ensure proper cleaning of fiber connectors before insertion and follow the equipment vendor’s guidance for hot-plugging optical modules. Verify compatibility with your switch or router model and update firmware if needed to ensure full feature support.
