Product information

Description

The TST AD-4LC/4LC single-mode fiber optic adapter provides a passive LC-to-LC coupling for 9/125 µm single-mode fibers. It is engineered to align two LC connectors precisely, enabling low insertion loss and stable optical performance. The adapter's compact form factor is suitable for installation in patch panels, wall outlets and fiber distribution boxes used in telecommunications and data networks.

Advantages

The adapter ensures reliable physical alignment of LC ferrules for consistent signal transmission and minimal back reflection. Its single-mode design supports standard 9/125 µm optical fibers and offers a compact footprint for dense installations. The passive construction requires no power and offers compatibility with common LC-terminated fiber cords and devices, making it a practical component for both rack-mounted and field deployments.

Suitable for

Connecting two single-mode LC patch cords in patch panels
Termination points in wall outlets and faceplates
Fiber distribution boxes and splice enclosures
Telecom links, backbone and access network segments
Data center fiber interconnects and equipment cabling

Key specifications

Fiber type: single-mode (9/125 µm)
Connector style: LC to LC simplex coupling
Operation: passive, no power required
Form factor: compact adapter suitable for patch panels and outlets
Performance: low insertion loss and stable mechanical alignment

How to use

Insert one LC connector from a single-mode patch cord into each side of the adapter until the connectors click or seat securely. Ensure connectors and adapter ports are clean and free from dust before mating to maintain low insertion loss and protect fiber endfaces. The adapter can be installed into compatible panel cutouts or mounted within a distribution box according to the enclosure's mounting provisions.

Usage recommendations

Clean connector endfaces with appropriate fiber cleaning tools before insertion and inspect using a fiber scope when possible. Avoid excessive mechanical stress on connected fiber cords and maintain bend radius limits for single-mode fiber to preserve optical performance and prolong component lifetime.
