Fiber optic QSFP28 cable BlueOptics 834972-B26, 15 m, multimode

BlueOptics QSFP28 cable model 834972-B26 is a 15 m multimode fiber-optic link designed for QSFP28 ports. It enables a direct optical connection between compatible high-speed transceivers and switches, offering a short-reach 100 Gbps link for data center interconnects, server racks and network equipment. The cable's multimode construction and factory-terminated connectors provide consistent signal transmission and straightforward installation in dense cabling environments.

Advantages

The cable supports short-reach 100Gbps operation over multimode fiber with standardized QSFP28 connectivity, reducing latency and port-to-port signal loss compared with copper alternatives. Its 15-meter length covers common rack-to-rack and equipment-to-equipment distances in data centers. Robust jacket and strain-relief at connector ends prevent damage during routing and handling, while factory-terminated ferrules ensure low insertion loss and reliable mating with compatible transceivers.

Key specifications

How to use

Inspect both cable ends and the transceiver ports before installation to ensure cleanliness and correct connector orientation. Route the cable avoiding sharp bends and high-stress points; maintain minimum bend radius recommended for multimode fiber. Insert the connector gently into the QSFP28 port until it seats; secure any retention clips if present. For removal, depress the latch and pull straight to avoid stressing the fiber. After installation, verify link status and test optical power and throughput with appropriate tools to confirm performance.

Recommendations

Use appropriate fiber cleaning tools before mating connectors and store unused cable ends with protective dust caps. Avoid tight bundles or pinch points and keep bend radius within manufacturer guidance. For critical links, perform optical loss and BER testing after installation and periodically during maintenance.
