## Long description

The InLine Fiber Optical Duplex Cable ST/ST 50/125µm OM3 25m is a multimode duplex fiber patch cable designed for reliable high-speed data transmission over short to medium distances. It has a 50/125 µm core/cladding diameter and OM3 performance characteristics, terminated with ST connectors on both ends. The 25 meter length supports flexible routing in structured cabling, telecom closets, server rooms and networked equipment requiring full-duplex links.
Advantages
This fiber optical duplex cable offers low insertion loss and consistent multimode performance appropriate for Gigabit Ethernet and other high-speed applications where OM3 modal bandwidth is beneficial. The duplex format enables simultaneous transmit and receive paths, while ST/ST connectors provide a secure bayonet-style connection that is widely used in industrial and enterprise installations. The 50/125µm core size with OM3 specification balances ease of termination and improved bandwidth compared with lower-grade multimode types.
Suitable for
 Short- and medium-range multimode networks in data centers and server rooms
 Full-duplex connections between switches, routers and transceivers
 Telecommunication closets and campus backbone links where OM3 is specified
 Industrial and laboratory environments that use ST connector interfaces
Key specifications
 Fiber type: Multimode OM3
 Core/cladding diameter: 50/125 µm
 Connector type: ST to ST duplex
 Length: 25 m
 Duplex configuration for simultaneous transmit and receive
How to use
Route the cable between equipment with matching ST connector ports, ensuring connectors are free of dust and debris before insertion. Align the bayonet slots, insert the ST connector and twist to lock for a secure connection. Use appropriate cable management such as ties or trays to avoid sharp bends; maintain the minimum bend radius recommended for multimode fiber to prevent excess attenuation. For installation in active networks, verify link status and run appropriate optical power or continuity tests to confirm signal integrity.
Ieteikumi lietošanai
Avoid exposing fiber ends to direct sunlight or contaminating surfaces. Use fiber cleaning tools on connector endfaces and perform optical testing after installation to confirm expected performance.
