Description
Overview
GAOTek PON optical amplifier is a low noise, high performance, FTTP high power, multi-ports optical amplifier with gain spectrum band within 1540 nm to 1563 nm. Each output port for optical amplifier has built-in well-performed CWDM. Every external up-link optical port of optical amplifier can connect with OLT PON port very conveniently. Each 1550 nm CATV’s output optical port multiplex 1310 or 1490 n’s data stream, to reduce the quantity of the component and improve the index and reliability of the system.
