Product Overview


Manufactured with premium G.657 A2 bend-insensitive fiber, this pigtail delivers exceptional performance even in tight routing scenarios common in terminal installations, minimizing signal loss caused by bending or cable management constraints. The fiber is terminated with industry-standard connectors on one end, with options including SC, LC, FC, and ST, ensuring compatibility with virtually all terminal equipment types .


The pigtail features a 900μm buffer coating with a protective outer jacket (LSZH or PVC options) for enhanced handling and durability during installation and maintenance. Each unit undergoes comprehensive testing for insertion loss, return loss, and mechanical stability, ensuring compliance with ITU-T and Telcordia standards for terminal connection reliability .

Primary component in residential terminal boxes, linking distribution fibers to optical network terminals (ONTs). The bend-insensitive design accommodates tight routing in consumer premises.


Industrial Terminal Equipment

Used in industrial control systems to connect fiber links to terminal servers and protocol converters. Supports reliable communication in harsh industrial environments.


Broadcast Terminal Interfaces

Facilitates connections between fiber distribution systems and broadcast equipment in studios and headends. Maintains signal integrity for high-definition video transmission.


Security System Terminals

Ideal for connecting fiber optic cameras to recording and monitoring terminals in security systems. Supports long-distance transmission with minimal signal loss.


FAQ


What connector type should I choose for my terminal application?

SC connectors are ideal for general terminal applications with their push-pull design and high durability.

LC connectors offer higher density for space-constrained terminals.

FC connectors provide superior stability for vibration-prone environments.

ST connectors remain compatible with legacy terminal equipment. Choose based on terminal interface, density requirements, and environmental conditions .


What is the advantage of bend-insensitive fiber for terminal pigtails?

Bend-insensitive G.657 A2 fiber reduces signal loss from tight bends (down to 5mm dynamic radius), a common issue in terminal boxes where cable routing space is limited. This prevents performance degradation caused by improper installation or accidental bending near terminals .


What length options are available for terminal pigtails?

Standard lengths range from 0.5m to 5m, with 1m and 2m being most common for terminal applications. Shorter lengths (0.5m) work well in high-density panels, while longer lengths (3-5m) provide flexibility for terminals with more complex routing requirements.


Can this pigtail be used with both single-mode and multimode terminal equipment?

No. This pigtail is specifically designed for single-mode terminal equipment. Using it with multimode equipment causes significant signal loss (>10dB) due to mode field diameter mismatch between single-mode and multimode fibers. Always match fiber types between pigtails and terminal equipment .


What maintenance procedures are recommended for terminal pigtails?

Periodically inspect connectors for contamination and clean with lint-free wipes and 99% isopropyl alcohol as needed. Check for excessive bending or strain near terminal connections. Replace dust caps after disconnecting to prevent contamination. Test optical performance annually using an optical loss test set to ensure insertion loss remains within specifications.
