Fiber optic transceiver CBO QSFP28-1D 100G 850nm

CBO QSFP28-1D 100G 850nm is a fiber optic QSFP28 transceiver module designed for short-reach multimode fiber links in data center and enterprise environments. The module supports 100 Gigabit Ethernet over 850 nm wavelength, offering high-density connectivity for switch-to-switch, server and aggregation deployments. It uses the standard QSFP28 form factor and provides straightforward plug-and-play integration with compatible network equipment that accepts QSFP28 interfaces.

Advantages

The transceiver delivers a compact, hot-pluggable solution for 100G multimode links with low latency and high port density. Its 850 nm design is optimized for short-reach multimode fiber runs, allowing simplified cabling and reduced footprint in racks and patch panels. Compatibility with standard QSFP28 ports ensures easy replacement or upgrade of existing equipment without custom wiring or significant configuration changes.

Suitable for

• Short-reach 100G links in data centers using multimode fiber (MMF)
• Switch-to-switch and switch-to-server connections
• Top-of-rack and aggregation layer deployments
• High-density rack installations requiring compact transceivers

Key specifications

• Data rate: 100 Gbps (QSFP28)
• Wavelength: 850 nm for multimode fiber transmission
• Form factor: QSFP28 hot-pluggable module
• Reach: short-reach multimode fiber links (designed for OM3/OM4 environments)
• Connectivity: standard QSFP28 electrical and optical interfaces

How to use

Install the transceiver by inserting the QSFP28 module into a compatible QSFP28 port on the network switch or server until it seats securely. Attach appropriate multimode fiber cables with compatible MPO/MTP connectors to the module’s optical interface, ensuring correct polarity. The device is designed for plug-and-play operation; after physical installation, verify link status and speed in the host equipment management interface and monitor for signal integrity and error counters as part of normal commissioning.

Recommendations

Use multimode fiber rated for the intended reach (OM3/OM4) and maintain clean connector endfaces to prevent signal loss. Ensure the host equipment supports 100G QSFP28 optics and verify firmware compatibility if required. For reliable operation, follow standard data center practices for fiber bend radius, cable management and environmental conditions.
