## Long description

The InLine Fiber Optical Duplex Cable ST/ST 50/125µm OM4 15m is a multimode fiber cable with a 50 µm core diameter and OM4 specification. Equipped with ST connectors on both ends, the cable supports full-duplex data transmission and is intended for short- to medium-range networking links up to 15 meters. It is compatible with OM4 systems and suited for installations requiring reliable, high-speed optical connections.
Advantages
This OM4 duplex fiber cable provides higher bandwidth and improved modal dispersion characteristics compared to lower OM types, enabling better performance for gigabit and multi-gigabit applications over the specified distance. ST/ST connectors offer secure bayonet-style coupling for stable connections. The 15 m length covers typical in-room and rack-to-rack connections while keeping signal loss within expected limits for multimode fiber.
Suitable for
Server room and data center interconnects
Short-distance backbone and patching between network equipment
Multimode fiber networks using OM4 specification
