StarTech OM4 Duplex Multimode Fiber Optic Cable LC/LC 50/125 µm 2 m LSZH 100 Gb

StarTech OM4 duplex multimode fiber optic cable, 2 m in length, terminates with LC connectors on both ends and is specified for 50/125 µm multimode fiber. Designed for short-range high-bandwidth links, this cable supports 40GBase-SR4 and 100GBase-SR10 connections and is compatible with SFP+, QSFP+ and other VCSEL- or LED-based transceivers. The cable features a low-smoke, zero-halogen (LSZH) jacket for reduced smoke and toxic emissions in the event of a fire, and each assembly is tested to meet optical insertion loss limits for reliable performance.

Advantages

This OM4 fiber cable provides high modal bandwidth for increased data throughput on short multimode runs and is backward compatible with existing 50/125 multimode infrastructure. The LC/LC duplex termination and zipcord construction enable compact, easy routing and quick connections in patch panels and transceiver ports. The LSZH jacket reduces smoke and corrosive gases if exposed to heat, making the cable suitable for environments with building-code or safety requirements. Individual testing ensures consistent insertion loss and predictable performance in 40/100 Gb networks.

Suitable for

• Data center short-reach links between switches, servers and transceivers
• Server interconnects using SFP+ and QSFP+ modules
• High-speed backbone or aggregation links in campus and enterprise networks
• Installations requiring low-smoke, zero-halogen cabling for safety compliance
• Connections between 40GBase-SR4 and 100GBase-SR10 transceivers

• Connector type: LC to LC duplex (LC/UPC to LC/UPC)
• Length: 2 meters
• Jacket material: LSZH (Low-Smoke, Zero-Halogen)
• Supported data rates: optimized for 40 Gbit/s and 100 Gbit/s multimode links
• Construction: zipcord duplex for flexible routing and strain relief

How to use

Inspect connectors and ensure dust caps are removed immediately prior to insertion. Route the cable without sharp bends and avoid exceeding the specified minimum bend radius to preserve optical performance. Plug each LC connector into the corresponding LC port on transceivers, patch panels or adapter plates until the latch clicks. For duplex links, maintain correct polarity (Tx-to-Rx) by following patch panel labeling or transceiver port assignments. Verify link status with appropriate SFP+/QSFP+ modules and network diagnostics to confirm acceptable insertion loss and signal integrity.

Usage recommendations

Store and handle the fiber cable in a clean environment and use fiber cleaning tools if connectors become contaminated. Use this OM4 cable for short-reach multimode connections where higher modal bandwidth is required; for longer multimode distances review transceiver and link budget specifications. Avoid routing near high-power electrical equipment and secure with non-metallic cable ties or management panels to prevent strain.
