## Long description

The Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G is a compact, hot-pluggable QSFP28 module designed for 100 Gigabit Ethernet over multimode fiber. Intended for short-reach links, the module fits high-density switches and routers to provide reliable server uplinks, data centre interconnects and aggregation connections. The module supports standard 100G SR4 signalling and offers compatibility with equipment that accepts QSFP28 form-factor transceivers.
Advantages
This fiber optic transceiver delivers high-density 100G connectivity in a small QSFP28 form factor, enabling efficient use of ports in network switches and routers. Its hot-pluggable design allows installation or replacement without interrupting other operations. Engineered for short-reach multimode fiber, the module provides predictable optical performance and interoperability with industry-standard multimode links. The product's compact size and thermal characteristics support deployment in dense data centre environments.
Suitable for
Data centre top-of-rack and spine-layer 100G interconnects
Server uplinks and aggregation links in enterprise and cloud environments
Short-reach multimode fiber links within racks or between nearby equipment rooms
Key specifications
Form factor: QSFP28 (quad small form-factor pluggable 28)
Data rate: 100 Gigabit Ethernet
Optical interface: SR4 for multimode fiber
Reach: short-reach multimode links (designed for intra-rack and nearby rack interconnects)
Connector: MPO/MTP-style parallel fiber connection
Power and thermal: low-profile QSFP28 power envelope suitable for high-density sites
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or host adapter until it latches. Connect the MPO/MTP multimode fiber cable to the module, taking care to align the connector keying and maintain clean fiber endfaces. After connection, verify link status and interface settings in the network device management interface and monitor optical parameters if supported. For hot-swap replacement, safely remove the module using the release mechanism and replace with a new unit while observing ESD precautions.
Usage recommendations
Use with approved multimode fiber cabling and ensure fiber connectors are clean before mating. Verify compatibility with the transceiver port and consult device documentation for supported link configurations and power budgets. Follow standard ESD handling procedures during installation and monitor module temperature in densely populated chassis.
