Key Features

Engineered For Performance

All Connector Types Covered

Single-source solution for LC, SC, FC, ST, and MU couplers — simplifying procurement and ensuring consistent quality across entire fiber infrastructure projects.

Ceramic and Bronze Sleeve Options

Zirconia ceramic sleeves for single mode applications requiring maximum precision (≤0.2dB), and cost-effective phosphor bronze sleeves for multimode installations.

Simplex and Duplex Variants

Full range of simplex and duplex configurations for every connector type, supporting both single-fiber and bi-directional fiber link requirements.

Panel-Ready Design

Standard panel mounting dimensions with snap-in or screw-mount flanges for immediate installation in patch panels, distribution frames, and terminal boxes.

Typical Applications

01

Fiber Patch Panels

Couplers as the core component in rack-mount and wall-mount patch panels, providing organized fiber cross-connect points in data centers and telecom facilities.

02

Distribution Boxes & Frames

Mating sleeves in outdoor and indoor distribution boxes, ODF frames, and fiber cabinets for network access, splitter, and distribution point termination.

03

Fiber Optic Testing

Couplers for connecting test equipment (OTDR, power meter, light source) to fiber under test, providing repeatable low-loss reference connections.
