ANALOG FIBER OPTIC TRANSCEIVER

Image
ECHO RF Solution provides various fiber optic products including fiber optic transceiver and components for this module such as WDM,coupler, laser diode and photo diode. The fiber optic transceiver consists of transmitting part(Donor unit) that converts RF signal into optic signal and receiving part(Remote unit) that converts optic signal into RF signal. The donor receives RF signal from base station and this signal is combined with modem signal(29 TX) in the donor unit. This signal comes to LD to be converted from RF to optic signal and this converted signal comes to PD to divide RF and Modem signals in remote unit. The modem signal(29.9MHz) is transferred to the modem(29 RX) for TTL communications(Interface : D-9PIN) in remote unit and RF signal goes out by TX out port for DUT. TX and RX paths have different wavelength, but it could be transmit signals via single optic cable using WDM(Wavelength Division Multiplexer). WDM has broadband wavelength(WDM : 1310+/-40nm & 1550+/-40nm) ...
