1550nm External Modulation Optical Transmitter (ZTX1800)
Tlhaloso ea Sehlahisoa
ZTX1800 ke mofuta o tloaelehileng oa "transmitter" e fetisang matla a kantle a 1550nm kantle ho naha e nang le phepelo ea motlakase e sebetsang habeli. Setsi sa leseli sa unit se amohela bandwidth e moqotetsane, lerata le tlase, leqhubu la laser la DFB le tsoelang pele, le fanang ka tšusumetso ea ho hasana. Ka lebaka la kamohelo ea lebitso la machabeng la likarolo tsa bohlokoa le theknoloji ea rona ea taolo ea ntlafatso ea khamphani, theknoloji ea taolo ea marang-rang ea SMNP, lits'oants'o tsa ts'ebetso ea mochini li lekanya ka botlalo boemo ba lisebelisoa tse ts'oanang tse tsoang kantle ho naha. E ka fana ka litšoantšo tsa boleng bo holimo, li-digital kapa li-compressed digital signal tse tsamaisang sebaka se selelele bakeng sa thelevishene ea cable le puisano ea mohala.
Likaroloana
(1) Boleng bo phahameng: Mahlale a mabeli a microwave le theknoloji ea RF ea pele ho khopama e netefatsa hore sistimi e ka fumana liphofu tse phahameng tsa CTB, CSO le SBS maemong a ts'ebetso e ntle ea CNR≥52dB.
(2) Ho tenyetseha: Ho netefatsa sistimi e phahameng ea ts'ebetso ea CSO, theknoloji ea module ea module ea kantle ea modulator e matlafatsa matla a Optical ho fiber ho fumana phetisetso ea sebaka se selelele, le tšimo e fetoloang ea SBS, 13, 16,18dB, AGC / MGC mode khetha, tšimo optimized OMI etsa hore ho loketse bakeng sa dinetweke tseo fapaneng phetiso.
(3) Ho ts'epahala: 19 "1U rack e tloaelehileng, e hahelletsoeng ka ts'ebetso e phahameng ea phepelo ea motlakase o matla, e ka sebetsa ho backup ho 85 ~ 265Vac City Network Voltage, switch switch ea MS-level; Chassis e futhumatsa taolo ea mocheso ka bo eona.
(4) Intuitive: Modulator e kantle le laser ke lisebelisoa tsa mochini tse turang ka ho fetesisa, mochini o nang le microprocessor e lekola boemo ba ts'ebetso ba modulator ea kantle le laser, fensetere ea LCD e bonts'a mekhahlelo ea ts'ebetso.
(5) Mofuta oa marang-rang: Khetha maemo ohle a ho lekola boemo ba sepakapaka ho fihlela maemo a naha le ho tsamaellana le maemo a SCTE HMS, e nolofalletsa botsamaisi ba taolo ea marang-rang.
(6) Phepelo ea motlakase e khonehang: e amohela lisebelisoa tsa aluminium, switch switch PSU, e sebetsa le 86 ~ 265VAC, e ka nkeloa sebaka ke -48VDC habonolo.
