Monoprice OM3 LC‑to‑LC 1M Duplex Fiber Cable

This multimode fiber optic cable offers a compact LC-to-LC duplex connection for 10Gb network links and short-distance backbones. It combines OM3 multimode fiber with a 50/125 µm core/cladding profile to keep signal loss low over common data center runs while resisting electromagnetic interference for cleaner transmission. If you need a one-meter jumper for switches, patch panels, or transceivers, this cable is a straightforward option.

Key Points

This LC to LC OM3 cable supports 10 Gigabit Ethernet performance over short to medium distances and is color-coded aqua for quick identification in crowded racks. The duplex design keeps transmit and receive channels paired and simplifies installation in typical network topologies. It uses multimode fiber manufactured to industry standards, which helps maintain consistent attenuation and return loss characteristics. Note that multimode OM3 has practical distance limits compared to single-mode fiber, so verify link budgets for runs longer than standard data center spans. 🔌

Usage Recommendations

Use this cable for patching between switches, connecting SFP+ transceivers, or linking horizontal cabling to rack equipment in enterprise closets. Its aqua jacket helps distinguish OM3 multimode lines from single-mode or other multimode grades during maintenance. For best results, avoid tight bends and kinks in the 2 mm jacket while routing through cable managers. Clean connector end-faces before mating to reduce insertion loss and protect optical performance. ⚡

Practical Notes and Limitations

This multimode jumper offers immunity to electronic interference, which makes it preferable in electrically noisy environments. However, OM3 is optimized for multi-gigabit links over relatively short distances according to industry guidance, and it may not meet distance requirements for long-haul or metro connections. Additionally, ensure that connectors on both ends match the transceivers or patch panels in use, since LC-to-LC is not compatible with devices expecting SC or other connector types unless adapters are used.
