3.1 Power Input: FWR-1000GSD is the external power supply input port, First should be the DC+5V external voltage stabilizer output line connected to the machine POWER IN, then put DC+5V external mano-stat insert 100/240 V, DC5V Face posted power light, show Power part is regular work.
3.2 Optical Input :1540-1560nm CATV optical signal reception, clean the end face by alcohol cotton ball before connection, when optical signal is input, and the optical receiving power range is at -15~+2dBm, the Laser indicator in the surface turns from red to green, shows that the photoelectric part is working normally; when the optical receiving power is >+2dBm, the Laser indicator turns yellow, shows the input optical power too high alarm, when the optical power <-15dBm, the Laser indicator turns red, shows the under-optical power alarm. PON port is connected to the ONU. When connecting, pay attention to cleaning the end of the patch cord, the insertion loss should be ≤1dB.
3.3 RF Output Level Adjustment : CATV: it's the RF output port, optical control AGC. When the optical input signal is input at -12~-2dBm, RF constant output at 82dBuv output(1.5dB). When the optical input signal is less than -15dBm, the RF output level also decreases. The relationship is that the optical signal drops by 1dB and the RF output drops by 2dB; however, the output level increases due to the excessive modulation of the pre-stage optical transmitter, otherwise it is smaller, the output level error is±2~3dB. The output level of the unit is the analog level, the digital level field strength meter measures 8dB, and the spectrum analyzer measures 10dB; when optical receiving power is > -2dBm, the RF output level will also increase. The relationship is that the optical signal rises by 1dB and the RF output level rise by 2dB. This level will increase and meantime the MER
index decreases. It is recommended that the optical receiving power should be designed within the optical control AGC range to prevent the optical receiving power from being too high to reduce the CTB/CSO index, and the optical receiving power is too small to reduce the CNR/MER index and affect normal reception of CATV signals.
4. Install & Test Attentions
4.1 This device is indoor structure and should not be used in places that are easily invaded by rainwater; it should have proper space in the indoor box to heat dissipation; the shielding net of the output cable must be grounded, and the grounding resistance should be less than 4Ω.
4.2 Patch cord input and cable output must be reserved for a certain length to avoid accidents. Please do not remove the seal If optical interface not to use. It's equipped with: IN SC/APC. During connection, better to apply the same adapters, do not apply different types.
4.3 RF output is directly connected to the user branch or distributor. The branch and distributor output null terminals must be connected with a 75Ω dummy load. Otherwise, the set-top box will cause mosaic due to the input impedance mismatch.
