High performance: Externally modulated technology, no laser chirp, low dispersion Distortion, high extinction ratio, with excellent characteristic within 40~862MHz.2.1+1 powers supply back, up hot-plug function available.3. Narrow bandwidth (0.65MHz), lower noise, DFB continuous wave laser, is propitious to Reduce the influence of the dispersion.4. The operating bandwidth is up to 47~1080MHz.5. CNR ≥ 53dB and excellent CTB, CSO index.6. SBS: 13~18dBm adjustable.7. ITU standard wavelength, ± 200GHz (± 1.6nm) adjustable.AGC/MGC mode is optional at spot. OMI can be optimized at spot.8. Perfect RS232 communication interface.9. Advanced SNMP network management function.10. Casing temperature auto-control.11. Excellent P/P ratio.Main application1. Used in main links and distribution network links in large and middle CATV stationHead-end.2. HT8500HU ITU wavelength adjustable, applicable to the value-added service of DWDMFiber optic CATV system and CFG dispersion compensation system.3. It can be used in branch FTTH that has high system index demand. Point to Point>65Km, CSO ≤ -65dB. It can provide high qualified and reliable value-added service such as RFTV, IPTV and VOD for the secondary users. It can also avoid the limitation of CSO deterioration and transmission distance caused by laser chirp for adopting 1550nm direct modulated optical transmitter.PerformanceIndexSupplementOptic featureOperating wavelength(nm)1548~1563HT8500HCITU-TG. 692HT8500HUWavelength ADJ. range(nm)± 1.6 (± 200GHz)HT8500HUWavelength ADJ. mode± 0.05nm steppingHT8500HULinewidth(MHz)Typ. =0.65FWHM(Δ λ ) (-3dB fullwidth)Side mode suppression ratio(dB)≥ 45SMSREquivalent noise intensity(dB/Hz)≤ -160RIN (20~1000MHz)Output power(dBm)2× 7Optional 2× 5, 2× 6, 2× 9, 2× 10Return loss(dB)≥ 50optical fiber connectorSC/APCOptional LC/APC, FC/APCRF featureWork bandwidth(MHz)47-86247~1000, 47~1080 optionalInput level(dBmV)18~28AGCFlatness(dB)≤ ± 0.7547~862MHz≤ ± 1.5862~1000MHz (optional)Return loss(dB)> 1647~1000MHzInput impedance(Ω )75RF portF-Femalelink featureTransmit channelPAL-D/60CHPAL-D/99CHCNR1(dB)≥ 53≥ 51.5Back to backCNR2(dB)≥ 51.5≥ 49.565Km optical fiber, 0dBm receiveCTB(dB)≤ -65≤ -65CSO(dB)≤ -65≤ -65SBS restrain(dBm)13~18AdjustableGeneral featureSNMP network management interfaceRJ45Communication interfaceRS232Power supply(VAC)90~26550/60Hz(VDC)-4830~72Power Consume(W)≤ 50Single power worksWork temp.(C)0~50Machine temp. control automaticallyStorage temp.(C)-40~85Operating relative humidity(%)5~95Size(" )19× 14.5× 1.75(W)x(D)x(H)
