1550nm External Modulation Optical Transmitter (ZTX1800)
Mafotokozedwe Akatundu
ZTX1800 ndi mtundu wa 1550nm transmitter opatsirana mwamphamvu wokhala ndi magwiridwe antchito apamwamba opangira magetsi awiri. Lonse unit kuwala gwero utenga yopapatiza bandiwifi, otsika phokoso, mosalekeza yoweyula DFB laser, amene ndi zothetsera kuchepetsa mphamvu ya kupezeka. Chifukwa cha kukhazikitsidwa kwa mtundu wapadziko lonse lapansi pazinthu zazikuluzikulu komanso ukadaulo wakukonza makina athu pakampani, SMNP ukadaulo wowongolera maukadaulo, zizindikiritso za makina pamakinawa zimakwaniritsa muyeso wazida zofananazo. Itha kupereka zithunzi zapamwamba kwambiri, ma digito kapena ma digito opanikizika akutali kwawayilesi yakanema ndi kulumikizana patelefoni.
Mawonekedwe
(1) Makhalidwe apamwamba: Ukadaulo wapawiri wama microwave ndi ukadaulo wa RF pre-kupotoza zimatsimikizira kuti dongosololi likhoza kukhala ndi zolinga zazikulu za CTB, CSO, ndi SBS pakagwiridwe ntchito bwino CNR≥52dB.
(2) Kusinthasintha: Poonetsetsa kuti magwiridwe antchito apamwamba a CSO, njira yosinthira gawo la modulator yakunja imakulitsa mphamvu ya fiber mu fiber kuti ipeze kufalikira kwakutali, komanso gawo lolowera SBS, 13, 16,18dB, AGC / MGC mode yosankhidwa, gawo lokhathamiritsa OMI limapangitsa kukhala koyenera kutengera ma netiweki osiyanasiyana.
(3) Kudalirika: 19 "1U rack yokhazikika, yopangira magwiridwe antchito yamagetsi yamagetsi, itha kugwira ntchito mu 85 ~ 265Vac City Network Voltage, kusintha kwa MS-level; galimotoyo kuzirala basi kutentha kutentha.
(4) Mwachilengedwe: Ma modulator akunja ndi laser ndizida zamagetsi zotsika mtengo kwambiri, makina okhala ndi microprocessor amayang'anira momwe zinthu zilili panja ndi laser, zenera la LCD likuwonetsa magwiridwe antchito.
(5) Mtundu wa network: Sankhani chitsimikizo cha Transponder chazinthu zonse kuti mukwaniritse muyeso wadziko lonse ndikugwirizana ndi muyezo wa SCTE HMS, imathandizira kuwunikira ma network.
(6) Mphamvu yamagetsi yosungika: imagwiritsa ntchito zotayidwa, chosinthira PSU, imagwira ntchito ndi 86 ~ 265VAC, itha kusintha ndi -48VDC mosavuta.
