## Summary description

Passive copper cable assembly QSFP28 CBO BlueOptics model 740-064981-BO, 20 m length, male-to-male connectors, designed for 100 Gbit/s data transmission. Intended for short-range high-speed interconnects between switches, routers and NICs supporting QSFP28 interfaces. Provides a cost-effective, low-latency direct connection for data centers and network racks.

## Long description

Passive copper cable assembly QSFP28 CBO BlueOptics model 740-064981-BO is a 20 m male-to-male direct attach cable engineered for 100 Gbit/s data transmission. It provides a reliable short-range high-speed connection between network devices with QSFP28 interfaces, suitable for inter-switch links, connections to routers and NICs in dense rack environments. The cable is designed for low latency and minimal power consumption compared with active optical alternatives, offering straightforward plug-and-play deployment in data centers and enterprise networks.
Advantages
This 20 m QSFP28 passive copper cable offers high throughput at 100 Gbit/s with low latency and predictable signal behavior for short-reach links. Being a passive assembly, it avoids the need for additional power and complex transceiver configuration. The male-to-male QSFP28 connectors ensure compatibility with standard QSFP28 ports, while the cable construction focuses on signal integrity and mechanical durability appropriate for rack-to-rack and shelf-level connections.
Suitable for
Short-range connections between switches and routers in data center racks
Direct links from servers or network interface cards (NICs) to aggregation switches
High-density rack interconnects where low latency and consistent throughput are required
Environments prioritizing cost-effective 100 Gbit/s links without additional power or optics
Key specifications
Interface: QSFP28 male-to-male
Length: 20 m
Nominal data rate: 100 Gbit/s
Cable type: Passive copper direct attach assembly
Use case: Short-reach, rack-to-rack or shelf-level interconnects
Latency: Low, passive electrical connection
How to use
Insert each QSFP28 connector into compatible QSFP28 ports on the devices to be connected, ensuring secure seating and locking of the connector latches. Use gentle handling to route the cable through rack channels or cable management arms to prevent sharp bends; maintain bend radii recommended by equipment vendors. Because the assembly is passive, no additional configuration or power is required on the cable itself — verify link status on connected devices and confirm negotiated speed and lane mapping in the network equipment interface statistics.
Usage recommendations
For reliable operation, keep the cable within the recommended bend radius and avoid tight cable bundles that could stress the connectors. Use this passive QSFP28 cable for short-distance, high-throughput links inside racks or between adjacent racks; for longer spans or where optical isolation is needed, consider active or optical transceiver solutions. Verify compatibility with your switch or NIC vendor supported cable list to ensure full interoperable performance.
