Fiber to the home ( FTTH ) broadband access is the ultimate development goal, optical receiver is the target terminal products for this goal.
This device adopts technology of high isolation WDM in order to separate CATV and ONU signal. Further more, it also adopts low optical power receiving and RF-AGC control technique, which could achieve the requirement of ≤-9dBmCATV receiving for FTTH.
The optical power receiving monitoring indicator LED ( ≥-15dBm) is provided on the pane and it supports RF outputs constantly , convenience of customers use, which is the ideal receiver equipment for FTTH.

3. Direction for Use
3.1 Power Input
POWER IN:It is the external power supply input port, First should be the DC+12 V external voltage stabilizer output line connected to the device POWER IN,than put DC+12V external mano-stat insert 100/240 V,DC12V Face posted power light, show power part is regularly working.
3.2 Optical Fiber Input
OPTICAL IN:It is input interface of optical signal,In optical access should clean APC TOP by alcohol ,than align adapter sunken mouth,fiber mouth march link;When optical signal accesses (≥-15dBm) then lights on in panel, which shows optical part is regularly working;ONU is 1490/1310nm connection interface, please do not take off the cover before you use.
3.3 RF Output Level Adjustment
RF OUT:It is RF output port,when optical input -4～-13dBm,RF output 70dBuv±1；ADJ:it is RF Output level attenuator, default value is the minimum.When the output level and the design requirements has any deviation, it can adjust the attenuation amount, with the design requirements.This device is low optical power receive, suggest-12 ~-9 dBm advisable.
