FTTH systems 3 Port 1550nm WDM Fiber Optic Components
Filter WDM 1310/1490/1550 nm Fiber Optic Components
GEZHI's Filter WDM 1310/1490/1550 nm Fiber Optic Components utilized thin-film filter technology. It multiplexes & demultiplexer three wavelength at 1310, 1490 & 1550nm that carry the voice, data and video services. The Filter WDM 1310/1490/1550 nm Fiber Optic Components combines and separates light to realize bidirectional communication signals at 1310/1490/1550nm wavelength in a wid range. Its used in the "triple-play" FTTH systems with 1 to 2 port configuration. 3 wavelengths are fed into the device through the common input port, one wavelength is reflected from one output port, simultaneously, the other 2 wavelengths pass through the device at other output port.
- 1310/1550nm FWDM - for WDM or DWDM optical communications
- 1480/1550nm FWDM - for high-power DWDM optical amplifier and EDFA
- 1510/1550nm FWDM - for DWDM multi-channel optical networks
- 980/1550nm FWDM - for high performance DWDM optical amplifier and EDFA amplifier
- 1310/1490/1550nm FWDM - for PON, FTTX and test instrument
- 1310/1550/1625nm FWDM - for testing active fibers in service
- 1310/1490/1550/1625nm FWDM - for combining or separating 1625nm channel with three triplex wavelength 1310nm, 1490nm and 1550nm so that 1625nm channel can be added into the existing triplex FTTH system
