I-1550nm Modulation Yangaphandle Transmitter Optical (ZTX1800)
Incazelo yomkhiqizo
I-ZTX1800 uhlobo olujwayelekile lwe-high-performance 1550nm modulation transmitter transmitter ene-high-performance switching switching supply. Umthombo wonke wokukhanya weyunithi usebenzisa umkhawulokudonsa omncane, umsindo ophansi, i-wave eqhubekayo ye-DFB laser, okulungele ukunciphisa ithonya lokuhlakazeka. Ngenxa yokwamukelwa komkhiqizo wamazwe omhlaba wezinto ezisemqoka nobuchwepheshe bokulawula ukusebenza kohlelo lwenkampani yethu, ubuchwepheshe bokulawula inethiwekhi ye-SMNP, izinkomba zokusebenza komshini ezisebenza ngomshini zilinganisa ngokuphelele izinga lemishini efanayo engenisiwe. Inganikeza ngemifanekiso esezingeni eliphakeme, ukudluliswa kwedijithali noma okucindezelwe ukudluliswa kwebanga elide kwamanethiwekhi wethelevishini nezokuxhumana ngocingo.
Izici
(1) Ikhwalithi ephezulu: Ubuchwepheshe bomthombo we-Dual microwave nobuchwepheshe be-RF pre-distension buqinisekisa ukuthi uhlelo lungathola izinhloso eziphezulu ze-CTB, CSO, ne-SBS uma kusebenza kahle kakhulu i-CNR≥52dB.
(2) Ukuzivumelanisa nezimo: Ekuqinisekiseni ukusebenza kohlelo oluphezulu lwe-CSO, ubuchwepheshe bokumodareyitha besigaba se-modulator yangaphandle bukhulisa amandla we-optical angene ku-fiber ukuze kutholakale ukudluliswa kwebanga elide, kanye nenkambu ye-SBS embundwini, 13, 16,18dB, AGC / Imodi ye-MGC iyakhethwa, inkambu eyenziwe nge-OMI iyenza ifanele ukudluliswa kwamanethiwekhi ahlukile.
(3) Ukuthembeka: I-19 "1U rack standard, eyakhelwe ngaphakathi ukusebenza okuphezulu kokushintshwa kwamandla kagesi, ingasebenza kubhekhaphu ku-85 ~ 265Vac City Network Voltage, MS-level switching othomathikhi; I-chassis epholisa ukulawula kokushisa okuzenzakalelayo.
(4) Enembile: I-modulator yangaphandle ne-laser yizinto zomshini ezibiza kakhulu, umshini onemishini ye-microprocessor uqapha isimo sokusebenza se-modulator yangaphandle ne-laser, iwindi le-LCD lephaneli libonisa imingcele yokusebenza.
(5) Uhlobo lwenethiwekhi: Khetha i-All-piece status Monitoring Transponder garanti yokuhlangabezana nezinga likazwelonke futhi ihambisane nezinga le-SCTE HMS, inika amandla amakhono wokuqapha ukuphathwa kwenethiwekhi.
