Product description
HT8800 all C band tunable CATV external modulation optical transmitter. The tunable range of wavelength: 1528.77~1563.86nm, the adjustable wavelength: >35nm. With the traditional ITU standard wavelength ±0.8nm( ±100GHz ) can tunable, is a completely new concept and application ranges.
It including all C band’s useable wavelength, Its database stores 89 ITU standard wavelength channels ( C band 0.4nm gallery interval ). Users can achieve the selection, switch and route etc wavelength management function quickly, accurately. High wavelength accuracy, high wavelength stability, fast tuning rate, perfectly adapt the NGB DWDM system. It’s high wavelength flexibility and replaceability will become the development direction of next generation broadcast television network ( NGB ) external modulation optical transmitter. Product features Full C-Band tunable, tunable range >35nm0.4nm interval, 89 ITU channels, database storageITU cord, Frequency, Wavelength three tunable ways, flexible and convenientFleible tunable speed (<20mS)High wavelength(frequency) lock precision(±0.02nm)High wavelength(frequency) stability (±0.012nm)Excellent side mode suppression, high extinction ratioLow noise, narrow linewidth ( Typ.=0.3MHz )Working frequency bandwidth up to 1050MHzExcellent system CNR,CTB,CSO indexSBS threshold 13 ~ 19dBm continuously adjustableThe safety and reliability of the telecommunication level , network management10/100M Ethernet interface, support SNMP, and WEB remote control and management1+1 power backup, support hot plug-ingExcellent cost performance Main applicationNext Generation Broadcasting ( NGB )FTTH, FTTx PON, RFoG, Triple-playNarrow plug data service as VOD, IP/QAM, etcReplacing traditional fixed wavelength 1550nm external modulation optical transmitterProviding highly wavelength flexible and replace abilityAs an alternate machine of ITU fixed-wavelength optical transmitter, to reduce the amount of inventory reservesFully use of existing fiber resources, achieving network upgrades and expansionThe CATV network with super capacity backbone and metropolitan area networksDynamic wavelength configuration, wavelength conversion, wavelength routingOptical path protection, DWDM line back upDynamic optical add-drop multiplexing (OAOM)DWDM system testTechnical index
