Izinhlobo ze-fiber amplifiers

Lapho ibanga lokudlulisa lide kakhulu (ngaphezu kwamakhilomitha ayi-100), isiginali ebonakalayo izoba nokulahlekelwa okukhulu. Esikhathini esedlule, abantu babevame ukusebenzisa abaphindayo be-optical ukukhulisa isignali ebonakalayo. Lolu hlobo lwemishini lunemikhawulo ethile kuzinhlelo zokusebenza ezisebenzayo. Esikhundleni salo yi-optical fiber amplifier. Isimiso esisebenzayo se-optical fiber amplifier siboniswa esithombeni esingezansi. Ingakhulisa ngqo isignali ebonakalayo ngaphandle kokulandela inqubo yokuguqulwa kwe-optical-electrical-optical.

 Isebenza kanjani i-fiber amplifier?

Ingakhulisa ngqo isignali ebonakalayo ngaphandle kokulandela inqubo yokuguqulwa kwe-optical-electrical-optical.

Yiziphi izinhlobo ze-fiber amplifiers ezikhona?

1. Isikhulisi se-fiber se-Erbium-doped (EDFA)

I-Erbium-doped fiber amplifier (EDFA) yakhiwe kakhulu yi-erbium-doped fiber, umthombo wokukhanya wepompo, i-coupler ye-optical, i-isolator ye-optical, nesihlungi se-optical. Phakathi kwazo, i-erbium-doped fiber iyingxenye ebalulekile yokwandiswa kwesiginali ye-optical, esetshenziswa kakhulu ukufeza ukukhuliswa kwesiginali ye-1550 nm Band, ngakho-ke, i-erbium-doped fiber amplifier (EDFA) isebenza kangcono ebangeni lobude be-1530 nm to 1565 nm.

AUbuhle:

Ukusetshenziswa kwamandla okupompo okuphezulu kakhulu (amakhulu kune-50%)

Ingakhulisa ngqo futhi ngasikhathi sinye isignali ebonakalayo ku-1550 nm band

Thola ngaphezu kwama-50 dB

Umsindo ophansi ekudlulisweni kwebanga elide

ukusilela

I-Erbium-doped fiber amplifier (EDFA) inkulu

Le mishini ayikwazi ukusebenza ngokubambisana neminye imishini ye-semiconductor

2.I-Raman amplifier

I-Raman amplifier ukuphela kwensiza engakhulisa amasiginali we-optical ku-1292 nm ~ 1660 nm band. Umgomo waso wokusebenza ususelwe kumthelela wokusakazeka we-Raman oshukumisayo ku-quartz fiber. Njengoba kukhonjisiwe esithombeni esingezansi, lapho ukukhanya kwepompo kudonswa Lapho isibonakaliso sokukhanya esibuthakathaka kuMann sithola umkhawulokudonsa kanye ne-wave light light wave kudluliswa ngasikhathi sinye ku-fiber optical, isibonakaliso sokukhanya esibuthakathaka sizokwandiswa ngenxa yomphumela wokusabalalisa we-Raman .

AUbuhle:

Uhla olubanzi lwamabhendi asebenzayo

Ingasetshenziswa kuzinhlelo zokusebenza ezifakiwe zemodi eyodwa

Ingangezela ukusilela kwe-erbium-doped fiber amplifier (EDFA)

Ukusetshenziswa kwamandla okuphansi, i-crosstalk ephansi

ukwehluleka:

High futha amandla

Uhlelo oluyinkimbinkimbi lokulawula ukuzuza

Kunomsindo

3. I-semiconductor fiber fiber amplifier (SOA)

Ama-semiconductor fiber fiber amplifiers (SOA) asebenzisa izinto ze-semiconductor njengezinzuzo zemidiya, futhi okokufaka kwabo kwesiginali yokukhanya kanye nokukhiphayo kunama-anti-reflection coatings ukuvimbela ukubonakala ekugcineni kobuso be-amplifier nokususa umphumela we-resonator.

AUbuhle:

ivolumu encane

Amandla okukhipha okuphansi

Umkhawulokudonsa wenzuzo mncane, kepha ungasetshenziswa kumaqembu amaningi ahlukene

Kushibhile kune-erbium-doped fiber amplifier (EDFA) futhi ingasetshenziswa ngemishini ye-semiconductor

Ukusebenza okungahambisani nolayini kokushintshashintsha kwenzuzo, ukuguquguquka kwesigaba esiphambanweni, ukuguqulwa kwamaza amade nokuxubana kwamagagasi amane kungafezeka

ukwehluleka:

Ukusebenza akuphakeme njenge-erbium-doped fiber amplifier (EDFA)

Umsindo ophezulu nenzuzo ephansi
