FWDM can realize the multiplexing and demultiplexing between two communication channel .It can expand the capacity of single fiber to achieve bidirectional communication, which can widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
PWDM is used for packaging of optical module. It can realize the multiplexing of two communication signal, which expands the capacity of single fiber and achieves bi-directional communication. It is widely used in optical network upgrade and expansion, or introduce new comprehensive business (CATV, TELECOM, integration of three networks-PON+EOC) etc.
GEZHI 200Ghz 1x2 DWDM Single Channel Optical Passive Component utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging to achieve optical add and drop at the ITU wavelengths.
This WDM coupler is used to combine or separate 1625nm channel with three triplex wavelength 1310nm, 1490nm and 1550nm. Using this device, 1625nm channel can be added into the existing triplex FTTH system.
GEZHI PON Multiplexer is based on thin film filter technology with T1550nm R1310&1490nm. The device features epoxy free optical path, low insertion loss, high extinction ratio, high reliability and high stability.
