StarTech.com 3m LC/UPC to LC/UPC OM4 Multimode Fiber Optic Cable 50/125µm

The StarTech.com 3m LC/UPC to LC/UPC OM4 multimode fiber optic cable (50/125µm) provides reliable duplex connectivity for 40 and 100 Gigabit networks. Designed for data centers and enterprise environments, this 3-meter patch cable uses laser-optimized multimode fiber (LOMMF) and LC/UPC terminations to ensure low insertion loss and consistent optical performance.

Advantages

The OM4 50/125µm construction delivers improved bandwidth at 850 nm and 1310 nm for VCSEL and LED sources, while precision ceramic ferrules maintain accurate fiber alignment to reduce loss. LC/UPC polished ends enhance return loss compared with older PC polish types. The LSZH (Low-Smoke, Zero-Halogen) jacket offers flame-resistant protection and reduced smoke/toxic emission in confined or poorly ventilated spaces. Each cable is individually tested to meet optical insertion loss limits, ensuring compatibility and dependable performance.

Suitable for

• Data center trunking and switch-to-switch links
• 40G and 100G Ethernet using multimode transceivers (SFP+, QSFP+ with appropriate breakout)
• High-density network racks and SAN connections
• Upgrading or maintaining OM3/OM4 multimode infrastructure

How to use

Inspect connectors and ports for debris before installation. Plug the LC duplex connectors into the corresponding LC ports on network devices, observing correct transmit/receive orientation. Route the cable through rack management and cable trays to avoid tight bends and sharp edges; maintain the manufacturer’s minimum bend radius for multimode fiber. After installation, verify link status and test optical loss to confirm the cable meets expected insertion loss values.

Usage recommendations

For reliable long-term performance, avoid excessive pulling force and repeated flexing of the cable, keep connector endfaces clean using appropriate fiber cleaning tools, and store spare cables in loops that respect the minimum bend radius. Use LSZH cable where building codes or enclosed environments require low-smoke, zero-halogen materials.
