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