## Summary description

QOLTEC 54019 is an InfiniBand / fibre optic network cable designed for high-speed data transmission between compatible networking and server equipment. It provides an optical connection for low-latency links and is suitable for data centre interconnects, storage networks and HPC clusters where InfiniBand-compatible optical cabling is required.

## Long description

QOLTEC 54019 is an InfiniBand-compatible singlemode fibre optic patchcord designed to provide a low-latency optical link between networking and server equipment. The cable uses LC/APC connectors on both ends and complies with G.652.D singlemode fibre standard. With a 3.0 mm jacket diameter and a 2 m length, this patchcord is intended for short interconnects in data centres, storage networks and high-performance computing (HPC) environments that require InfiniBand optical cabling.
Advantages
The LC/APC to LC/APC termination ensures low back-reflection and reliable signal integrity for singlemode optical links. Compliance with the G.652.D standard guarantees predictable attenuation and dispersion characteristics for long-distance singlemode transmission. A 3.0 mm outer diameter provides a balance between flexibility and mechanical protection, and the 2 m length is convenient for rack-to-rack and equipment-to-equipment connections within server rooms.
Suitable for
InfiniBand interconnects in HPC clusters
Optical connections between switches, host channel adapters and storage arrays
Data centre patching and fibre-panel connections
Short-distance singlemode runs inside server racks and equipment cabinets
Key specifications
Connector type: LC/APC to LC/APC
Fibre type and standard: Singlemode, G.652.D
Cable diameter: 3.0 mm
Length: 2 m
Patchcord construction: Single-fibre singlemode
Optical performance: low back-reflection (APC) suitable for low-latency links
How to use
Inspect both connectors and fibre ends for cleanliness before installing. Gently insert the LC/APC connectors into compatible sockets on InfiniBand switches, host channel adapters or transceivers until they click into place. Route the 3.0 mm cable to avoid sharp bends and mechanical stress; maintain minimum bend radius as recommended by the fibre manufacturer. For removal, depress the connector latch and pull straight out without twisting. Regularly check connectors and clean with appropriate fibre cleaning tools to maintain optimal optical performance.
Usage recommendations
Use this singlemode LC/APC patchcord in systems that explicitly support InfiniBand optical modules and singlemode fibre. Avoid using APC-terminated cables with APC-incompatible transceivers or adapters. Store unused fibres in protective sleeves and avoid tight bundling; perform connector cleaning before critical connections to minimize attenuation and reflection.
