Fiber Optic Cable LC-LC IBM 5M 39M5697

The IBM Fiber Optic Cable LC-LC 5M (model 39M5697) is a multi-mode fiber cable engineered for high-speed data transmission in rack and data center environments. With a 5-metre length and a 50 µm core diameter, it uses LC connectors at both ends to provide stable, low-loss connections suitable for InfiniBand and other high-bandwidth interconnects. The cable is compatible with equipment requiring small form factor duplex LC-type connectors and is intended for direct connection to drive ports and networking interfaces that accept LC terminations.

Advantages

This LC-LC fiber cable offers predictable signal performance across a 5 m span and low insertion loss due to its LC duplex connectors. The 50 µm core supports multi-mode transmission characteristics suited to short- to medium-reach interconnects. Its standardized LC termination ensures broad compatibility with networking hardware that uses small form factor duplex LC connectors, enabling straightforward plug-and-play installation in racks and expansion units.

Suitable for

• Connecting InfiniBand or Ethernet devices in data centers and server racks
• Linking EXP810 storage expansion unit drive ports and similar LC-based interfaces
• Short- to medium-distance multimode fiber runs within networking closets

Key specifications

• Length: 5 metres
• Fiber type: multimode
• Core diameter: 50 µm
• Connector type: LC to LC duplex
• Intended use: high-bandwidth, low-latency interconnects (e.g., InfiniBand)

How to use

Inspect both LC connectors and device ports for dust or damage before installation. Align the LC duplex connector with the device port and insert until it clicks, ensuring the latch engages. Route the cable to avoid tight bends and mechanical stress; maintain the minimum bend radius recommended for multimode fiber. To disconnect, depress the LC latch and pull the connector straight out. For connections to an EXP810 storage expansion unit or similar equipment, use the LC duplex connector end to plug directly into the drive ports designed for small form factor LC terminations.

Использование и уход

Store the cable coiled without sharp bends and keep protective dust caps on unused connectors. Clean fiber end faces with appropriate fiber cleaning tools before mating to minimize insertion loss and protect transceivers and ports.
