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 -2~-9/-12/-15dBm,RF output 82/76/70dBuv±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.
4. Install Test Matter Need Attention
4.1.This 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, This device is with SC/APC,do not link with SC/PC.
