Product Description

Product Overview

The FTTH FBG Optic Bragg Reflector is a high-reliability 1650nm wavelength selective reflector designed for Fiber-to-the-Home projects. It enables accurate optical link monitoring without disrupting normal communication signals.

Key Features & Benefits

High Reflectivity at PON End: Reflects nearly 100% of OTDR test pulses at 1650nm while allowing communication wavelengths to pass with minimal attenuation
Exceptional Reliability: Fiber grating encapsulated within ceramic ferrule for protection against insertion/removal damage and contamination
Easy Installation: Available in SC and LC types, compatible with standard adapters
Online Monitoring: Enables rapid fault detection without interrupting normal network traffic
Wide Compatibility: Works with GPON, EPON, GEPON, 10GEPON, and NGPON systems

Applications

Create high reflectance at PON termination without disturbing traffic
Test reflectance from central office locations
Verify optical continuity during subscriber activation and troubleshooting
FTTH, FTTB, FTTC network deployments
