ACT multimode OM1 fiber patch cable duplex 2 m, 62.5/125 µm core, MT-RJ to ST, LSZH

ACT multimode OM1 fiber patch cable duplex 2 m, 62.5/125 µm core, MT-RJ to ST, LSZH is a duplex multimode fiber patch cable designed for short-reach network connections. The cable has two 62.5/125 µm (OM1) multimode cores and a Low-Smoke Zero-Halogen (LSZH) outer jacket. One end is terminated with an MT-RJ connector and the other with an ST connector to provide full-duplex links between equipment such as switches, patch panels and transceivers.

Advantages

This ACT fiber patch cable is manufactured and tested to industry standards to ensure reliable signal transmission and consistent performance. The OM1 62.5/125 µm multimode cores are suitable for legacy multimode installations and short-distance data, voice and AV links. The LSZH jacket reduces halogen emissions in the event of fire, making the cable suitable for installations where low smoke and low toxicity are required.

Suitable for

• Short-reach multimode network links
• Connections between switches, patch panels and transceivers
• Data center or telecom equipment with MT‑RJ and ST ports
• Voice and AV installations requiring multimode fiber

When it may not be suitable

This cable uses OM1 62.5/125 µm multimode fiber, which is intended for short-distance links and legacy multimode environments; it may not support higher-bandwidth or longer-distance multimode or single-mode applications. It is not suitable where single-mode fiber is required or where higher-grade multimode (OM3/OM4/OM5) is specified for higher-speed short-reach applications.

Key specifications

• Fiber type: Multimode OM1
• Core/cladding diameter: 62.5/125 µm
• Configuration: Duplex (two fiber cores)
• Length: 2 m
• Connectors: MT‑RJ to ST
• Jacket material: LSZH (Low-Smoke Zero-Halogen)

How to use

Route the duplex fiber cable between the MT‑RJ port on one device and the ST port on the corresponding device or patch panel. Ensure connectors are clean before mating to minimise insertion loss. Align and insert each connector until it latches securely. Avoid tight bends and maintain the manufacturer's minimum bend radius during installation to preserve optical performance.

What to consider before purchase

• Verify that connected equipment supports MT‑RJ and ST connectors.
• Confirm that OM1 62.5/125 µm multimode fiber meets your distance and bandwidth requirements.
• Check whether LSZH jacket is required for your installation environment.

Usage recommendations

Use this ACT duplex OM1 fiber patch cable for short-distance multimode links in patch panels, switches and AV or voice equipment. Keep connectors clean, avoid tight bends, and store excess length in a loose coil to maintain performance.
