Fiber Deep Optical Node node N8702 - Platform for the NGCS - Improves bandwidth for advanced services - Fiber deep node - Innovative coast effective design - Compact size - Services for commercial and residential application The model N8702 is NetWave’s latest generation 870MHz optical node Platform. This platform allows a maximum value node for service provider who are looking for the fiber deeper into new and current HFC network. The N8702 offers the flexibility to function as a single output node in fiber deep architectures. The N8702 is the perfect solution for increasing bandwidth and revenues with limited capital expenditures. 1550nm region CWDM return transmitters allows system operators to maximize the benefit of reduced number of return path fiber cables. The standard features include 15Amps power passing capability, Crowbar surge protection and plus the deeper lid contain a fiber tray plus, option module of the Network Monitoring transponder. 9 Optical Transmitter Optical operating wavelength : 1310 ± 10nm ‰ Laser type : FP / DFB LD ‰ Fiber Connector : SC / APC ‰ Optical power ( nominal ) : FP : 1mW, DFB : 3mW ‰ RF Operating bandwidth : 5 to 42MHz ‰ 9 Optical Receiver Optical operating wavelength : 1310 ± 20nm or 1550 ± 20nm ‰ Photodiode type : Hybrid dynamic range PIN diode ‰ Fiber Connector : SC / APC type ‰ Optical input range : -3.0 to +2.0 dBm ‰ RF Operating bandwidth ‰ 9 RF Amplifier module RF Operating bandwidth : 5 ~ 870MHz ( 5~42MHz, 54 ~ 870MHz) ‰ Impedance : Nominal 75 ohm ‰ Operating power voltage : +5,+12,+24VDC ‰ AC Power passing is capable the each port. ‰ Plug-in Equalizer and Attenuator. ‰ 40/90 or 110 Volt powering ‰ Specifications Optical Section • Wavelength • Optical input Range • Indicators (Voltage) • Accuracy • Return Loss • Connector • Housing Pass Band 1310 and 1550 ±20nm -3 ~ +2 dBm 1V / mW 1dB ≥ 55 dB SC/APC Type 5 to 1002 MHz RF Section Forward • Bandwidth • Frequency Response • Operation Gain(@870MHz) • Reference Out Level@ (Optical input 0dBm ) • Operation Slope • Attenuation by pads (level adjust) • Equalizer by pads • CTB (Composite Triple Beat) • CSO (Second Oder Beat) • X-MOD (Cross Modulation ) • CIN (Carrier-to-Intermodulation Noise) • HUM-MOD@15A • Noise Figure • Return Loss • Test Point, all Accuracy Reverse 54MHz ~ 870MHz ± 0.75 dB >45 dB 870 / 550 / 55 MHz 48.5 / 35 / 26 dBmV 55 / 550 / 870 MHz 0 / 9 / 13.5 dB Plug-in type 0-20 dB Plug-in type -3 to 20 dB < -67 dBc (127dB㎶) < -65 dBc (125dB㎶) < -63 dBc (123dB㎶) 52 dBc < -65 dBc (125dB㎶) < 7 dB < - 16dB ± 0.1 dB 5MHz ~ 42MHz ± 0.75 dB >17 Flat dB 19.5 (@42/65MHz) dBmV Plug-in Type 0-20 dB Plug-in Type 0-12dB < -60 dBc (120dB㎶) < 6 dB < - 16dB ± 0.1 dB Environmental • Operating Temperature Range • Storage Temperature Range • Humidity Range - 40 ~ +65 ℃ / -40 ~ +149º F - 40 ~ +70 ℃ / -40 ~ +158º F 0 ~ 95 % Power Requirements (with AGC) • Line Power AC Input Voltage • Power Consumption • DC Voltage • AC Bypass current • DC Current • AC Voltage, 60Hz 60 ~ 90 VAC 23 W + 24.0 ±0.25 V 15A 600mA @40 / @50 / @60 / @70 / @80 / @90 VAC 1.08 / 0.85 / 0.72 / 0.64 / 0.58 / 0.53 A Mechanical • Weight • Housing Dimension 7.5 Kg 367× 229× 190 (W×H×D) mm www.net-wave.co.kr Specifications Optical Section Wavelength 1310 and 1550 ±20nm Optical input Range -3 ~ +2 dBm Indicators (Voltage) 1V / mW Accuracy 1dB Return Loss ≥ 55 dB Connector SC/APC Type Housing Pass Band 5 to 1002 MHz RF Section Forward Reverse Bandwidth 54MHz ~ 870MHz 5MHz ~ 42MHz Frequency Response ± 0.75 dB ± 0.75 dB Operation Gain(@870MHz) >45 dB >17 Flat dB Reference Out Level@ (Optical input 0dBm) 870 / 550 / 55 MHz 48.5/ 35 / 26 dBmV 19.5 (@42/65MHz) dBmV Operation Slope 870 / 550 / 55 MHz 13.5/ 9 / 0 dB - Attenuation by pads (level adjust) Plug-in type 0-20 dB(1.0dB Step) Plug-in Type 0-20dB(1.0dB Step) Equalizer by pads Plug-in type -3 to 20 dB(1.5dB Step) Plug-in Type 0-12dB(1.5dB Step) CTB (Composite Triple Beat) < -67 dBc (127dB㎶) - CSO (Second Oder Beat) < -65 dBc (125dB㎶) - X-MOD (Cross Modulation ) < -63 dBc (123dB㎶) - CIN(Carrier-to-Intermodulation Noise) Opitcal Input 0dBm 52 dBc - HUM-MOD@15A < -65 dBc (125dB㎶) < -60 dBc (120dB㎶) Noise Figure < 7 dB < 6 dB Return Loss < - 16dB < - 16dB Test Point, all Accuracy ± 0.1 dB ± 0.1 dB www.net-wave.co.kr Specifications & Block Diagrams Environmental Operating Temperature Range - 40 ~ +65 ℃ / -40 ~ +149º F Storage Temperature Range Humidity Range - 40 ~ +70 ℃ / -40 ~ +158º F 0 ~ 95 % Power Requirement Line Power AC Input Voltage 60 ~ 90 VAC Power Consumption 23 W DC Voltage + 24.0 ±0.25 V AC Bypass current 15A DC Current 600mA AC Voltage, 60Hz ,@VAC/A @40/1.08A , @50/0.85A , @60/0.72 , @70/0.64 , @80/0.58 , @90/0.53A Mechanical Weight 7.5 Kg Housing Dimension 367× 229× 190 (W×H×D) mm Optical INPUT Photo Diode Factory Trim PAD #1 H PAD #2 FWD Equalizer AMP L AC Bypass RF Output 1 AMP Optical Monitoring Alarm LED Opt.
