Om3 pigtail fiber

An OM3 ST fiber optic pigtail is a short multimode fiber with a pre-terminated ST connector on one end and exposed fiber on the other, designed for high-speed data transmission in telecom, data centers, and industrial networks.

Overview

OM3 pigtails are multimode fibers with a 50/125 µm core/cladding diameter, optimized for high-bandwidth applications such as 10 Gigabit Ethernet over short distances. The ST connector features a bayonet-style coupling with a 2.5 mm ferrule, providing reliable and durable connections for field installations. The exposed fiber end allows for fusion or mechanical splicing to trunk cables or patch panels, ensuring seamless integration into existing networks .

Key Features

• High Performance: OM3 fibers support high-speed data transmission with low insertion loss and minimal signal degradation .
• Durable Construction: Pigtails often include tight-buffered 0.9 mm jackets and flame-retardant coatings for safety and resilience in industrial environments .
• Connector Options: Available in ST, SC, LC, and FC connectors, with ST being ideal for field installations due to its bayonet design .
• Color Coding: Pigtails are typically color-coded (e.g., aqua for OM3) to simplify identification and organization in high-density setups .
• Ease of Installation: Designed for high-density splicing panels, pigtails allow quick and reliable fusion or mechanical splicing .
• Versatile Applications: Suitable for telecommunication networks, data centers, LAN/WAN connections, fiber sensing, and testing instruments .
