Isingeniso
I-SRB series optical receiver iyi-receiver ye-optical yohlobo lwangaphakathi ewusizo eyenzelwe ukuhlangabezana nephrojekthi yokuvuselela i-network fiber. Lo mkhiqizo unama-port okukhipha e-RF angu-1 kuya kwangu-2. Futhi usethe umsebenzi we-optical AGC uma i-+2dBm ~ -6dBm uma ithola okukhiphayo ingagcinwa ku-106dBµV ngaphezulu (okubili); igobolondo kusetshenziswa igobolondo le-aluminium elibunjiwe.
Izici Zokusebenza
- I-broadband yesikhulumi esingu-45MHz kuya ku-1000MHz kanye nesikhulumi sokuklama amafasitela amabili esingu-1310, 1550;
- Isekethe yokucindezela ukukhuphuka ephelele ene-high-pass filter, enokumelana okunamandla nokushaywa kombani kanye nokuvimbela umthelela wokukhuphuka;
- umklamo wokusetshenziswa kwamandla aphansi, ukusetshenziswa kwamandla okuphelele kungaphansi kuka-15W; futhi inesibonisi sedijithali kanye nomsebenzi wokusebenza ku-inthanethi.
- Ama-transponder ohlobo lwe-II angasetshenziswa ；
