Key Features

Engineered For Performance

Dual Form Factor Options

Available as male-female plug-in for inline use or female-female adapter type for integration into patch panels and distribution frames, offering maximum deployment flexibility.

Precision Fixed Attenuation

Factory-calibrated attenuation values from 1dB to 25dB with ±1.0dB accuracy ensure consistent, repeatable signal reduction across the specified wavelength range.

CATV-Grade Return Loss

APC polish option delivers ≥60dB return loss, meeting the stringent back-reflection requirements of analog CATV and RF-over-fiber distribution systems.

Broad Connector Compatibility

SC interface matches the most widely deployed connector type in FTTH and telecom infrastructure, enabling drop-in installation with existing patch cords and equipment.

Typical Applications

01

FTTH / PON Power Management

Equalizes optical power levels at ONU receivers in GPON and XGS-PON networks where subscribers are located at varying distances from the OLT.

02

CATV Signal Balancing

Attenuates optical signals in cable television head-end and distribution networks to prevent receiver overload and maintain optimal signal-to-noise ratio.

03

Fiber Distribution Frames

Integrates into ODF and fiber patch panels as adapter-type attenuators for centralized optical power management at telecom central offices.
