## Long description

The BlueOptics FN-CABLE-QSFP56-DAC-LB2 QSFP56 2m Black is a passive direct attach copper (DAC) cable engineered for high-speed, short-reach interconnections in data centers and enterprise networks. At 2 meters length and fitted with QSFP56 connectors, this cable supports 200Gb/s aggregated bandwidth when used with compatible QSFP56 ports and devices. It is intended for reliable rack-to-rack or switch-to-switch links where low latency and consistent signal integrity are required. The black jacket and compact twinax construction provide a practical solution for dense cabling environments.
Advantages
The cable offers low-power, low-latency connectivity compared with active optical solutions for short distances, with no external transceivers required. Its passive design reduces heat generation and power consumption while providing consistent electrical performance for high-bandwidth applications. Durable outer jacket and secure QSFP56 connectors ensure stable mechanical connection and simplified installation in dense network racks.
Suitable for (tasks / use cases)
 Short-reach interconnects between switches and routers within the same rack or adjacent racks
 High-bandwidth server-to-switch connections in data center topologies
 Low-latency links for high-performance computing and storage networks
 Temporary or permanent cabling in enterprise aggregation and spine-leaf architectures
Key specifications
 Connector type: QSFP56 to QSFP56
 Cable type: Passive direct attach copper (DAC), twinax
 Length: 2 meters
 Color: Black
 Supported link rate: Designed for 200Gb/s aggregated bandwidth (compatible with QSFP56 interfaces)
 Typical use range: Short-reach interconnects within racks or between adjacent racks
How to use
Ensure that both network devices have compatible QSFP56 ports and support passive DAC cables at the intended link rate. Power down or follow hot-plug procedures recommended by the equipment vendor, align the QSFP56 connector keying with the port, and insert the connector until it latches. For removal, retract any release mechanism and pull the connector straight out to avoid damaging the port. Route the cable to avoid tight bends and secure it within the rack to prevent strain on connectors.
Usage recommendations
Use this QSFP56 DAC for short-reach high-bandwidth links where low latency and reduced power consumption are priorities. Avoid exceeding recommended bend radius and protect connectors from contaminants. Verify compatibility with the equipment vendor’s specifications for passive QSFP56 cables to ensure link negotiation at the desired data rate.
