Tlhaloso e Khutšoanyane
SR2020AW, e nang le bandwidth ea ts'ebetso ea 47 ~ 1000MHz, ke papali e nang le matla a tlase, e sebetsang hantle, e bolokang chelete e ngata, FTTH CATV optical receiver, Ebang e sebelisoa thelevisheneng ea analog kapa thelevisheneng ea dijithale. Lihlahisoa tse nang le li-tubes tse nang le kutlo e phahameng ea optical receiver le lerata le khethehileng le tsamaisanang le lerata. Ho fumana matla a phahameng a optical ho ka fetoloa ke boemo ba PAD, ho bapaloa ho fokotsa tlhahiso, kahoo SR2020AW ka har'a mefuta e mengata e matla ea matla a amohelehang a +2 dBm ~-21dBm, e na le litšobotsi tse babatsehang.
Ho bapala ka makhetlo a mararo, fiber lapeng, ho sebelisa SR2020AW ho ka boloka lisebelisoa tse ngata tsa matla a optical fiber amplifier. Bakeng sa basebelisi, ho ka fokotsa haholo litšenyehelo tsa ho haha marang-rang.
Likarolo tse sebetsang
1. Lerata le tlaase-tlase (3.8% modulate, -10dBm amohela, CNR ≥ 45.3dB)
2. Lethathamo le pharalletseng la ho amohela matla a optical: ka har'a Pin=-16, MER≥36.1dB
3. GPON e sebetsang, EPON, e lumellanang le theknoloji leha e le efe ea FTTx PON
4. E ka boloka palo e kholo ea lisebelisoa tsa matla a optical, 'me ea fokotsa marang-rang hahololitšenyehelo tsa ho lokisa
5. Ka har'a 47 ~ 1000MHz bandwidth, kaofela li na le likarolo tse ntle tse bataletseng (FL≤±0.75dB)
6. Metal case, fana ka tšireletso bakeng sa lisebelisoa tsa optic electronic sensitive
7. Boemo bo phahameng ba tlhahiso, bo ka sebelisoang ke basebelisi ba bangata
8. Tšebeliso e tlaase ea matla, ts'ebetso e phahameng, ts'ebetso ea theko e phahameng
HLOKOMELA
1. Adapter ea matla bakeng sa thepa ena: Input 110/220V; Sephetho sa DC 12V(0.6A).
2. Boloka sehokelo sa optical se hloekile, sehokelo se sebe se tla baka boemo bo tlase haholo ba tlhahiso ea RF.
3. Ha ea lokela ho ikamahanya le bona, ho qoba tšenyo ea sesebelisoa.
