Applications
ZION COMMUNICATIONS' Fiber Optic Attenuator reduces optical signal energy to prevent distortion in optical receivers caused by excessive input power. This optical passive device is essential for debugging optical power performance, calibrating fiber optic instruments, and attenuating fiber signals to required levels.
Primary Applications
- Optical fiber communication systems
- Fiber optic CATV networks
- High-power optical device measurement
- Signal power adjustment to optimal receiver levels
Connector Types

LC Connector
Used in LC fiber interfaces with modular jack (RJ) latch mechanism. Commonly used with SFP modules in routers.

SC Connector
Applied to SC fiber interfaces, featuring a flat design similar to RJ-45 but with copper contact pins.

FC Connector
Features metal sleeve reinforcement with turnbuckle fastening. Typically used on ODF distribution frames.

ST Connector
Round shell design with turnbuckle fastening. Commonly used in fiber distribution frames for 10Base-F connections.
