## Summary description

The InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM4 20m is designed for high-speed data transmission. It features a core diameter of 50 µm and supports full duplex communication. With LC and ST connectors, this cable ensures compatibility with various devices. Ideal for networking and telecommunications, it provides reliable performance over long distances, making it perfect for both home and professional use.

## Long description

The InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM4 20m is a multimode fiber patch cable engineered for high-speed data transmission and full duplex communication. Combining an LC connector on one end with an ST connector on the other, this 20-metre cable uses a 50/125 µm core/cladding geometry and OM4-grade multimode glass to support increased bandwidth and reduced modal dispersion compared with lower OM ratings. It is intended for backbone, horizontal and equipment interconnects where reliable optical signal quality and connector compatibility are required.
Advantages
This duplex fiber cable provides low insertion loss and predictable attenuation across OM4 wavelengths, enabling stable performance for short- and medium-range links. The mixed LC/ST connector configuration offers cross-compatible connectivity to devices with LC ports and legacy equipment using ST interfaces. The 20 m length allows flexible placement of network devices without signal repeaters for many installations, and the multimode OM4 specification supports higher modal bandwidth for modern switch and server environments.
Suitable for
Fiber patching between switches, patch panels and transceivers in data centres and server rooms
Connecting network equipment that uses LC and ST connectors
Horizontal cabling in office LANs and campus networks
Telecommunications links that require full duplex multimode connections
Key specifications
Fiber type: Multimode OM4
Core/cladding diameter: 50/125 µm
Connector types: LC (one end) and ST (other end), duplex
Length: 20 m
Mode: Duplex (bi-directional full duplex over two fibers)
Typical applications: 10 Gbps and higher multimode networks over short to medium distances
How to use
Inspect connector endfaces and ensure dust caps are removed just before connection. Align and insert the LC connector into the LC receptacle until it clicks, and insert the ST connector into the ST socket with a quarter‑turn bayonet lock to secure it. Route the cable to avoid sharp bends and maintain the minimum bend radius specified for multimode fiber to prevent increased attenuation. When disconnecting, release the LC latch and rotate the ST connector to unlock before pulling straight out. Follow standard fibre handling procedures to avoid contamination or physical damage.
Usage recommendations
Use a visual fault locator or optical power meter to verify link continuity and measure insertion loss after installation. Keep spare dust caps for unused connectors and perform routine cleaning of connector endfaces with appropriate fiber cleaning tools. For links requiring longer distances or single-mode transmission, select an appropriate single-mode fiber cable instead of multimode OM4.
