Introduction to the PLC optical divider

by:Fiber Hope     2020-07-27

PLC optical divider is a modern one of important passive optical components in optical network, it USES the semiconductor chip technology ( Lithography, imaging techniques such as) Production, optical waveguide array on the chip surface, the shunt function focus on chips, it was a chip to realize the shunt. PLC optical divider is widely used in broadband passive optical network ( BPON) , gigabit passive optical network ( GPON) , Ethernet passive optical network ( EPON) , 10 g Ethernet passive optical network ( 10 g EPON) , 10 g gigabit passive optical network ( 10 g GPON) Such as application, is an important part of FTTH network.

working principle of the PLC optical divider

unlike traditional discrete devices, PLC device made of semiconductor process can not function of optical element integrated on a chip, is to realize the photoelectric integrated device, modular, miniaturization of foundation technology.

the two key parts of the PLC optical divider: namely, chips and optical fiber array. Chip made by semiconductor technology, optical waveguide array on the chip surface, the shunt functional integration in each node ratio as a 50:50, respectively on both ends of the chip coupling input out of the multi-channel optical fiber array and encapsulate waveguide optical path. Optical fiber array made of V groove using fiber special adhesive technology to realize precise positioning and high reliability, to meet different needs. Thermal expansion coefficient matching packaging design to ensure that the optical fiber array board without stress, high reliability and high temperature optical fiber displacement. Face Angle according to needs accurate grinding, conform to the Telcordia GR - 1209 - The CORE and GR - 1221 - The CORE standard.

PLC optical divider advantages

loss is not sensitive to light wavelength, can meet the demand of different wavelength of transmission light evenly, the signal can be evenly distributed to the user compact structure, small volume, does not occupy large installation space multiplexing of low cost, branch number, the more the more obvious cost advantage is
