OTDR FBG Fiber Bragg Grating Reflector
FBG Reflector is a wavelength selective filter, which is usually installed at the front end of the ONU of the optical network to achieve accurate and fast detection of the end-to-end attenuation of the optical link.
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.
