GEPON OLT Rau P2MP Daim Ntawv Thov
General
Lub HDV ZL5432099-ICS transceiver nrog txhawb cov ntaub ntawv tus nqi ntawm ib txwm 1.25 Gbps rau GEPON OLT daim ntawv thov mus txog 20km kis tau tus mob nyob deb, nws tau tsim lub rooj sib tham nrog Tuam Tshoj Telecom EPON cov cuab yeej kev xav tau V2.1 1000BASE-PX20+ specifications.SC recceptacle yog rau kho qhov muag interface.
Lub module muab cov ntaub ntawv kuaj mob digital ntawm nws cov kev ua haujlwm thiab cov xwm txheej, suav nrog kev xa hluav taws xob, laser kev tsis ncaj ncees, txais cov khoom siv hluav taws xob kho qhov muag, qhov ntsuas kub, thiab cov khoom siv hluav taws xob.Calibration thiab tswb / ceeb toom pib cov ntaub ntawv raug sau thiab khaws cia hauv lub cim xeeb sab hauv (EEPROM).Daim ntawv qhia nco tau sib xws nrog SFF-8472, raws li qhia hauv daim duab 2. Cov ntaub ntawv kuaj mob yog cov nqi A/D nyoos thiab yuav tsum tau hloov mus rau hauv lub ntiaj teb tiag tiag units uas siv calibration tas li khaws cia hauv EEPROM qhov chaw 56 - 95 hauv A2h.
