ORTE 2X2 Wavelength Division Multiplexer optical Isolator Hybrid (WDM-ITAP) with High stability and Reliability
WDM ISO TAP hybrid device, which integrates WDM, isolator, and split-coupling, can be used for erbium-doped fiber amplifier backpumping. It provides a way to obtain network traffic while maintaining normal network traffic. The Test Access Port (TAP)/ Traffic Access Port (TAP) is an emerging integrated device for network monitoring. It does not need to provide internal power and belongs to the passive optical network device. TAP can be used to monitor network performance, troubleshoot network failures, analyze network traffic, and prevent malicious attacks. In general, the wDM-ISO-TAP hybrid device is used for EDFA backpumping, which is more difficult to implement. This device can be used in the backpumping part of EDFA. The hybrid device structure has the advantages of small size, low cost and easy optical path.
