Intangiriro
SRB series optical receiver ni igikoresho cyo kwakira optique cyo mu nzu gikozwe mu buryo bufatika kugira ngo gihuze n'umushinga wo kuvugurura fibre y'umuyoboro. Iki gicuruzwa gifite imiyoboro ya RF 1 kugeza kuri 2. Kandi shyiraho imikorere ya AGC optique iyo +2dBm ~ -6dBm iyo wakira umusaruro ushobora kuguma kuri 106dBµV hejuru (ibiri); igikoresho gikoresheje icyuma cya aluminium.
Ibiranga imikorere
- Umuyoboro mugari wa platform kuva kuri 45MHz kugeza kuri 1000MHz na platform y'amadirishya abiri ya 1310, 1550;
- Urugendo rwiza rwo guhosha umuvuduko w'amazi rufite akayunguruzo gakomeye, gafite ubudahangarwa bukomeye n'inkuba kandi hirindwa ingaruka z'umuvuduko w'amazi;
- Imiterere y'ingufu nke ikoreshwa, ingufu zose zikoreshwa ni munsi ya 15W; kandi ifite ecran ya digitale na function yo gukoresha kuri interineti.
- Transponders zo mu bwoko bwa II zishobora gukoreshwa ；
