GWT3500 1550nm Ikwirakwiza CATV
Ibisobanuro ku bicuruzwa
GWT3500 ni modulisiyo itaziguye 1550nm ya DFB yohereza kuri TV igereranya, TV ya digitale na CMTS byerekana gukwirakwiza fibre yuzuye hamwe na QAM TV Ikimenyetso cya fibre ndende.Ikwirakwiza rikoresha umurongo muremure wa DFB laser, RF power digital automatic process technique, hamwe na RF mbere yo kugoreka byakozwe na Greatway Technology.Muri microprocessor yubatswe ikurikirana imiterere yimikorere kandi ihita itanga imikorere myiza.GWT3500 ninziza yo gukwirakwiza fibre ya TV muri 20Km na QAM TV yerekana intera ndende muri 100Km.
Fibre yatangijwe kugirango ikwirakwize CATV RF mu myaka ya za 90 kubera kwiyegereza kwayo no kwaguka kutagira umupaka.RF to fibre ihindura ibikoresho nibikoresho byingenzi.Hamwe n'amajwi make yongerera imbaraga na microprocessor, imbaraga zose za RF kuri lazeri zirashobora gushyirwaho neza, byemeza neza icyerekezo cyiza cya optique (OMI).Lazeri ikonje ya DFB muri transmitter itanga umurongo uhoraho wa DWDM optique yumurongo wo gutangaza cyangwa gushyiramo serivisi zoguhuza serivisi.Hagati aho laser ya DFB ikonje ifite laser RIN nziza (urusaku rukomeye rwurusaku) hamwe nimbaraga zihamye za laser.Ortel-Emcore umurongo muremure ukonje DFB laser hamwe na Greatway igishushanyo byagaragaye ko ari byiza guhuza.GWT3500 ya transmitter ya optique yakoreshejwe cyane nabakiriya bo muri Amerika ya ruguru, Amerika yepfo nu Bushinwa hamwe nibikorwa byiza kandi byagaragaye ko byizewe.
Hamwe na Greatway power power optique amplifier, transmitter ya GWT3500 irashobora gutanga ibyuma byerekana ibimenyetso bya TV byujuje ubuziranenge inyubako cyangwa fibre murugo.
Ibindi biranga:
• Urusaku ruke umurongo muremure Ortel-Emcore yakonje laser ya DWDM DFB.
• GaAs cyangwa GaN Technology kugeza 1218MHz.
• Ubuhanga buhebuje mbere yo kugoreka butezimbere CTB, CSO na C / N.
• Muri microprocessor yubatswe neza ikurikirana neza imbaraga za laser nubushyuhe.
• Nibyiza kuri CATV isakaza RF cyangwa Narrowcasting RF kuri fibre.
• Imbere yimbere VFD yerekana ibipimo byimiterere nubutumwa bwimikorere.
• SNMP gucunga imiyoboro idahwitse.
• 1310nm yumurambararo utabishaka.
