The 1-to-16 Plug-in PLC Optical Fiber Splitter efficiently distributes an optical input signal into sixteen output paths with minimal signal degradation. It features low insertion loss and high uniformity, ensuring balanced signal distribution across all channels. Operating across the full wavelength spectrum (1260-1650nm), this splitter maintains excellent temperature stability and reliability. Its compact plug-in design allows for easy integration into existing fiber management systems. This device is widely used in FTTx networks, PON systems, and local area networks to enable efficient multi-point optical signal distribution for broadband services.
