Fiber optic patch cord StarTech 7m LC/UPC to LC/UPC OM4 50/125µm LSZH (full duplex)

The StarTech 7m LC/UPC to LC/UPC OM4 50/125µm LSZH full-duplex fiber optic patch cord provides a multimode connection designed for high-speed networks. With LC/UPC connectors on both ends and OM4 laser-optimized multimode fiber, this 7 metre zipcord supports VCSEL and LED sources at 850 nm and 1300 nm and is suited for 40G and 100G transceivers. The LSZH outer jacket and aramid fiber sheath deliver reduced smoke and improved mechanical protection for use in data centres, server rooms and other controlled environments.

Advantages

This OM4 multimode cable offers high bandwidth and low insertion loss suitable for demanding short‑reach applications. The duplex LC/UPC terminations and zipcord construction provide easy routing and simple full‑duplex connectivity. The LSZH jacket minimises smoke and corrosive gases in the event of a fire, while the aramid reinforcement increases tensile strength and durability. Each fibre is factory tested to ensure optical loss falls within acceptable limits.

Suitable for

• Data centres and server racks
• Switch-to-switch and switch-to-transceiver connections (SFP+, QSFP+)
• 40GBase-SR4 and 100GBase-SR10 short‑reach links
• Storage area networks (SANs) and high-density patch panels

• Construction: zipcord with aramid fiber sheath
• Optimised wavelengths: 850 nm and 1300 nm (VCSEL/LED sources)
• Typical use: supports 40G and 100G multimode transceivers

How to use

Route the duplex LC patch cord between the equipment ports ensuring the correct transmit/receive orientation for full‑duplex operation. Insert LC connectors into the corresponding LC ports until they click into place. Avoid tight bends and kinks; respect the manufacturer’s minimum bend radius to maintain optical performance. When removing the cable, depress the connector latch and pull straight out to prevent damage to the connector or port.

Usage recommendations

For optimal performance, keep connectors clean and capped when not in use, use compatible multimode transceivers rated for OM4 fiber, and follow structured cabling best practices in patch panels and cable management to minimise insertion loss and reflections.
