WDM Optical Receiver Instructions
Fiber to the home ( FTTH ) broadband access is the ultimate development goal, RX100 optical receiver is the target terminal products for this goal. RX100 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 ≤-9dBm CATV 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.
2. Main Performance Parameters
≥40（1310/1490nm and 1550nm )
receive power range
output level adjustment
≥14（75Ω characteristic impedance）
RF output interface
Metric (two way output)
3. Direction for Use
3.1 Power Input
POWER IN：RX100 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：RX100 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;lights will be changed by receive power as yellow(>2dBm), green(2～-12dBm) and red (<-12dBm).ONU is 1490/1310nm connection interface, please do not take off the cover before you use.
3.3 RF Output Level Adjustment
RF OUT：RX100 is RF output port,when optical input -2～-12dBm,RF output 78dBuv±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.
4. Install Test Matter Need Attention
4.1．RX100 device is indoor type structure,Not to be used in place of harassment by the rain;Packed in the box of the indoor appropriate space,For cooling;The output of the cable shielding network must be grounded,Grounding resistance should be less than 4 Ω,The local power supply for electrical shell has to be grounded,Above ground resistance.
4.2．Tail fiber input and output cable has to be reserved certain length,Reduce accident’s occurrence; optical interface do not move if not use, RX100 device is with SC/APC,do not link with SC/UPC.
RX100 Outlay power supply, AC100～240V DC12V 500mA 1 PCS.
