ANALOG FIBER OPTIC TRANSCEIVER

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) and WDM in Donor unit can cover all signals from diffrent remote units. The usage for fiber optic modules are for fiber optic communications system to solve radio shadow area. Star(1:1) and Cascade configuration(1:N) up to 5Wave are available according to customer’s specific requests and it is possible to design Analog and Digital fiber optic modules. Transmission distance of fiber optic cable is available up to 20Km with single fiber, but the design applying EDFA is possible up to 100Km. Our products are cost-effective solutions and we guarantee the quality for 2 years and comply with RoHS Compliant.
