1625nm FBG Fiber Optic Reflector

The 1625nm FBG Fiber Optic Reflector (Fiber Bragg Grating) is a specialized passive component designed for real-time monitoring of FTTH (Fiber to the Home) networks. As a core part of our Fiber Optic Reflector product line, it acts as a high-precision band-pass filter, reflecting only the specific 1625nm monitoring wavelength from an OTDR while allowing standard communication signals (1310/1490/1550nm) to pass through without interference.

Key Applications & Use Cases

• OTDR Link Monitoring: Ideal for central office technicians to verify link integrity and identify fiber breaks without disrupting user data.

• PON (Passive Optical Networks): Essential for GPON, EPON, and XG-PON network maintenance where high-reflectivity at 1625nm is required for precise fault location.

• FTTH Network Protection: Installed at the subscriber side (ONT) to provide a clear “end-of-line” signal for remote testing systems.

• Live Fiber Testing: Allows for “in-service” testing, ensuring that maintenance work does not result in signal downtime for the end customer.
