Fiber Optical Duplex Cable InLine 82525P SC/ST 50/125µm OM4 25m

The InLine Fiber Optical Duplex Cable 82525P SC/ST 50/125µm OM4 25m is a 25-metre duplex multimode fiber patch cable designed for high-speed data transmission in networking and telecommunications environments. The cable uses OM4 grade multimode fiber with a 50/125 µm core/cladding geometry, providing improved bandwidth and lower attenuation for short to medium distance links. One end is terminated with two SC connectors and the other end with two ST connectors, enabling direct interconnection between equipment with different connector types.

Advantages

The OM4 multimode construction offers higher modal bandwidth compared with lower-grade multimode fibers, supporting gigabit and multi-gigabit links with reduced modal dispersion. Duplex configuration ensures simultaneous bidirectional data flow over a single cable assembly, simplifying cable management while maintaining full-duplex operation. The mixed SC to ST terminations provide flexibility for connecting legacy devices with ST interfaces to modern switches or patch panels that use SC connectors. The 25 m length balances reach and manageability for structured cabling runs in data centers, server rooms, and telecom closets.

Suitable for

• Connecting switches, routers and patch panels with SC and ST ports
• Short- to medium-range multimode links in LANs and data centers
• Telecommunications equipment interconnects and fiber distribution frames
• Testing and lab environments requiring mixed connector types

Key specifications

• Fiber type: OM4 multimode
• Core/cladding diameter: 50/125 µm
• Connector types: 2 × SC on one end, 2 × ST on the other end
• Configuration: Duplex (two fibers)
• Length: 25 metres
• Typical applications: Gigabit and multi-gigabit multimode links

How to use

Route the duplex cable along the intended cable path and secure it to avoid tight bends or compression. Insert the SC connectors into SC ports until the latch engages and align and insert the ST connectors into ST ports, engaging the bayonet coupling to lock them in place. Ensure both fibers are correctly matched for transmit and receive channels to maintain full-duplex communication. Perform optical loss testing or continuity checks after installation to verify connection quality and to ensure attenuation remains within acceptable limits for the intended link distance and data rate.

Usage recommendations

Avoid bending the cable below the recommended minimum bend radius and protect connector endfaces from dust and contamination by using protective caps when connectors are not in use. Store and handle the cable to prevent kinks and excessive tensile load; clean connector endfaces with approved fiber cleaning tools before connecting to active equipment. For best performance in structured cabling, route the cable separate from high-voltage power lines and follow site grounding and fiber management practices.
