PLC planar waveguide -type optical splitter is a quartz substrate integrated waveguide -based optical power distribution device , a small size, wide operating wavelength range (1260-1650nm), high reliability, uniformity and good spectral characteristics . Widely based on FTTX PON structure of various types of projects (EPON, BPON, GPON , etc. ) connected to the central office and the terminal equipment and to achieve an optical signal splitter .
Product meets and exceeds Telcordia GR1209/1221 standard
Feature
Planar waveguide technology using a semiconductor device production process of the optical waveguide branches , branching functions on the chip is completed , the above can be achieved up to 1X32 branches on a chip , then the chips are coupled to both ends of the input and output of the package end multi-channel fiber array .
The advantages of this device are ( a ) the wavelength of the light transmission loss is not sensitive to different wavelengths to meet transmission requirements. ( 2 ) the spectral uniformity , can be uniformly allocated to the user signal. ( 3 ) compact structure , small size, can be installed directly in the various existing transfer box , no special installation designed to leave a lot of space . ( 4 ) Many single channel shunt device can reach 32 or more. Low ( 5 ) multi-channel cost , the more points ones , the cost advantage is more obvious.
