Fiber Bragg Grating FBG Filter Customized by the OTDR on Optical Network ONUs

OTDR FBG Reflector is based on Fiber Bragg Grating technology with wide bandwidth and low insertion loss to reflect OTDR test signal. When the optical measurement system generates a certain range of wavelength to a Passive Optical Network (PON) which can pass through the FBG, the FBG will reflect its own intrinsic reflection wavelength at 1644.5nm - 1655.5nm.

FBG Reflector (1550nm)
FBG Reflectors (1550nm), also known as FBG filters, are usually installed at the front end of optical network ONUs. Combined with OTDR equipment, they can realize point-to-point (PTP) or point-to-multipoint (PTMP) network monitoring of optical links. It can accurately and quickly reflect network anomalies.

FBG Reflector (1650nm)
FBG Reflector (1650nm) utilizes the wavelength-selective properties of the Fiber Bragg Grating, and the FBG is embedded in the adapter. It can be easily installed in the front end of the optical network (ONU), and cooperate with the Optical Time Domain Reflector (OTDR) to quickly and accurately realize the fault detection of the optical network.

Pigtail Typed FBG Reflector

Characteristics	Applications
* High precision of reflectance at test wavelength * Low insertion loss at traffic wavelength * Easy to install * Exceptional reliability and environmental stability * Applicable for FTTH, FTTB, FTTC * Compatible with GPON, EPON, GEPON, 10GEPON, NGPON	* Create high reflectance and wide working bandwidth at the termination of a PON without disturbing traffic * Test the reflectance from the central office. * Check optical continuity of a subscriber when being added, or when troubleshooting

1. The FBG reflector creates high reflectivity at the PON end, which will not affect the communication

The fiber grating reflector uses fiber grating to reflect nearly 100% of the test light pulse sent by the OTDR on the OLT side of the optical link terminal, and the wavelengths that do not meet the conditions pass through the fiber optic reflector normally with a small attenuation.

When the OTDR detects that the reflected detection signal exists, the optical fiber connection at the user end is normal. If the reflection value is very low or there is no reflection, it indicates that the fiber at the user end is damaged or broken. It can make online rapid detection of optical fiber lines without affecting the normal communication of other communication signals.

2. High stability and reliability of FBG reflector
The fiber grating reflector uses the light sensitivity of the fiber material to write the fiber grating on the fiber core. The optical fiber goes through the ceramic ferrule and the grating area is partially encapsulated inside the ceramic ferrule. The fiber grating will not be affected during the insertion and removal of the fiber optic reflector and it will not be affected by dirt, so it has high reliability.

3. The FBG reflector and the adapter structure are easy to connect.

Fiber optic reflectors are available in SC type and LC type. They interact with regular adapters. It is very convenient to use them.

With the widespread implementation of fiber-to-the-home FTTH projects, the number of users involved in optical networks continues to increase. How to quickly and accurately detect optical network faults is particularly important for the mainte
