The BELDEN INC. FPSLULU03M5 is a singlemode OS2 fiber optic patch cable terminated with LC duplex connectors on both ends. It is designed for low-loss signal transmission in structured cabling systems, data centers, telecom rooms, and industrial network environments. The 3.5-meter length suits rack-to-rack and equipment-to-patch-panel runs where a standard 3-meter cord falls just short. Licensed electricians, low-voltage cabling contractors, and network infrastructure technicians are the primary installers of this cable type.
This patch cable is suited for singlemode OS2 fiber applications in both commercial and light industrial installations. Typical use cases include connecting fiber switches, transceivers, media converters, and patch panels in structured cabling infrastructure. The LC duplex form factor is common in high-density data center environments and enterprise network closets where space-efficient connectors are required.
Designed as an OEM-style replacement or direct-fit patch cable for OS2 singlemode fiber infrastructure using LC duplex-port equipment.
Installation is performed by licensed low-voltage cabling contractors or qualified network technicians in accordance with TIA-568 structured cabling standards. Power down or place active transceivers in a safe state before connecting or disconnecting fiber patch cords. Never bend the cable beyond its minimum bend radius, and avoid applying tension to the connector boots. Clean fiber end-faces with an approved fiber optic cleaning tool before mating to prevent contamination-related signal loss.
