ACT 7 meter LSZH Multimode 50/125 OM3 fiber patch cable duplex with LC and ST connectors

The ACT OM3 Fiber Patch Cable 7m Duplex with LC to ST connectors is a multimode 50/125 µm fiber designed for high-speed, short- to medium-range data links. The 7 meter length supports flexible routing in racks and patch panels while the duplex configuration enables simultaneous transmit and receive channels for full-duplex communication. Constructed with an LSZH jacket, this cable reduces smoke and eliminates halogen emissions, improving safety in confined or public spaces where low-toxicity materials are required.

Advantages

This OM3 cable provides consistent multimode performance thanks to the 50/125 µm core sizing and OM3 specifications, which support higher modal bandwidth for applications such as 10 Gigabit Ethernet at typical campus and data center distances. The duplex LC–ST connector pairing ensures compatibility with equipment that uses LC ports on one end and ST ports on the other, simplifying integration across mixed-connector installations. The LSZH outer jacket offers enhanced fire-safety characteristics without compromising cable flexibility for routing in trays and conduits.

Suitable for

• Patch panels and rack-to-equipment connections in data centers and server rooms
• Campus backbone links and horizontal distribution within office buildings
• Connections between switches, transceivers and fiber media converters with LC or ST ports
• Environments requiring low-smoke, zero-halogen cabling for safety compliance

Key specifications

• Fiber type: Multimode OM3
• Core/cladding diameter: 50/125 µm
• Length: 7 meters
• Configuration: Duplex (two fibers for TX/RX)
• Connectors: LC (one end) to ST (other end)
• Jacket material: LSZH (Low Smoke Zero Halogen)
• Typical use: Short- to medium-distance multimode data links

How to use

Route the duplex cable between devices ensuring correct alignment of transmit and receive channels: connect the LC connector to the device or transceiver with an LC port and the ST connector to the device or panel with an ST port. Avoid tight bends and respect the manufacturer’s minimum bend radius to maintain optical performance. Secure the cable in cable management hardware to prevent strain on connectors and to preserve insertion loss characteristics over time.

Recommendations

For best results, verify connector cleanliness before mating and use appropriate dust caps when connectors are not in use. Test end-to-end link performance after installation with an optical tester suited for OM3 multimode fiber to confirm insertion loss and continuity meet network requirements.
