Product Description：
OTU interface card is Sharetop Technology Co.,Ltd. product , It's fiber optic link wavelength converter (optic signal amplifier) . the principle is optic-electrical-optic , re-start the optical signal, achieve the optic signal amplifier and converter . cooperation with cwdm/dwdm can achieved WDM transmission system . Especially suitable for 125M/155M/622M/1.25G/2.5G/4G SDH/SONET, Ethernet and other optic telecommunication systems . It provides a fast and low-cost transmission solution for optical fiber transmission lines with shortages of fiber resources.
