Fiber patch cable BlueOptics QSFP28 100G QSFP-to-QSFP passive 3 m

BlueOptics QSFP28 100G fiber patch cable in blue is a 3 meter passive QSFP-to-QSFP assembly engineered for short-reach 100 gigabit links. The cable provides a direct interconnect between QSFP and QSFP28 ports on switches, routers and optical transceivers commonly used in data centers and network racks. With a passive design, it delivers a cost-effective, low-latency connection for compatible 100G equipment where active signal conditioning is not required.

Advantages

The cable offers a compact, factory-terminated connection that eliminates the need for separate transceiver modules and external patching infrastructure for short-distance links. Its passive QSFP-to-QSFP format reduces power consumption compared with active optical cables, while maintaining the signal integrity required for 100G Ethernet and other high-speed protocols. The 3 m length balances reach and cable management in rack-to-rack and intra-rack installations.

Suitable for

• Short-reach 100G connections between QSFP/QSFP28 ports in data center switches and routers
• Interconnects between optical transceivers and network equipment in rack and shelf deployments
• Low-latency links in high-density aggregation and spine/leaf network topologies

Key specifications

• Connector type: QSFP-to-QSFP (QSFP28-compatible form factor)
• Data rate: 100 Gbit/s
• Length: 3 m
• Cable type: Passive direct-attach cable for short-reach interconnects
• Color: Blue

How to use

Insert each QSFP connector into the corresponding QSFP or QSFP28 port on the equipment until the connector latches. Verify port alignment and module compatibility before powering the equipment. After connection, confirm link status using the device management interface or LEDs. For removal, press the latch or extraction mechanism and pull the connector straight out to avoid damaging ports. Handle the cable by the connector bodies and avoid sharp bends or kinks; maintain the specified bend radius to preserve signal performance.

Usage recommendations

Use this passive 3 m QSFP-to-QSFP cable for short-distance rack and row interconnects where active optical conversion is unnecessary. Ensure both ends are compatible with QSFP/QSFP28 port specifications and verify that the host devices support passive direct-attach cables at 100G. Store and route the cable to avoid tight bends, mechanical strain, and exposure to contaminants that could affect connector integrity.
