Kev Taw Qhia
SRB series optical receiver yog ib qho khoom siv sab hauv tsev uas tsim los ua kom tau raws li qhov project kho dua tshiab ntawm lub network fiber. Cov khoom no muaj 1 txog 2 qhov chaw nres nkoj RF. Thiab teeb tsa lub luag haujlwm optical AGC thaum + 2dBm ~ -6dBm thaum tau txais cov zis tuaj yeem tswj tau ntawm 106dBµV saum toj no (dual); plhaub siv lub plhaub txhuas cam khwb cia.
Cov yam ntxwv ua haujlwm
- 45MHz txog 1000MHz platform broadband thiab 1310, 1550 dual qhov rai tsim platform;
- Lub voj voog tiv thaiv hluav taws xob zoo meej nrog lub lim dej siab dhau, nrog kev tiv thaiv zoo rau xob laim thiab tiv thaiv kev cuam tshuam ntawm hluav taws xob;
- tsim kev siv hluav taws xob tsawg, tag nrho kev siv hluav taws xob tsawg dua 15W; thiab muaj cov zaub digital thiab kev ua haujlwm online.
- Hom II transponders siv tau;
