Gịnị bụ Fiber Optic Delay Line OFDL

Fiber Optical Delay Line (OFDL) bụ ngwaọrụ nwere ike nweta oge igbu oge nke akara ngosi. Site n'iji igbu oge, ọ nwere ike nweta ngbanwe oge, nchekwa ihe niile na ọrụ ndị ọzọ. Ọ nwere ngwa dịgasị iche iche na radar nhazi usoro, usoro nkwurịta okwu fiber optic, elektrọnik countermeasures, nyocha sayensị na nnwale, na mpaghara ndị ọzọ. Edemede a ga-amalite site na ụkpụrụ bụ isi nke ahịrị igbu oge fiber optic, na-elekwasị anya na ndapụta ngwa yana otu esi ahọrọ ahịrị igbu oge kwesịrị ekwesị.
Ụkpụrụ ọrụ
Ụkpụrụ bụ isi nke eriri eriri fiber optic na-egbu oge bụ na a na-ebufe mgbaàmà ngwa anya nke a ga-egbu oge site na ogologo ogologo eriri eriri fiber optic, na n'ihi oge achọrọ maka nnyefe ọkụ na eriri fiber optic, a na-enweta oge igbu oge nke mgbaàmà anya. Dị ka egosiri na eserese 1, ahịrị igbu oge fiber optic kacha dị mfe bụ sistemụ mejupụtara ngwaọrụ dị ka lasers, modulators, eriri nnyefe, na fotodetector nwere ọrụ igbu oge. Ụkpụrụ na-arụ ọrụ: Mgbama RF nke a ga-ebunye na mgbama ngwa anya nke laser na-ewepụta na-abanye n'ime modulators dị iche iche. Ndị modulators na-emegharị akara ngosi RF na ọkụ ka ha wee mepụta mgbama anya na-ebu ozi RF. Mgbama ngwa anya na-ebu ozi RF jikọtara ya na njikọ fiber optic maka nnyefe, na-egbu oge ruo nwa oge, wee rute fotodetector. Onye na-ahụ maka foto na-atụgharị mgbama ngwa anya enwetara na-ebu ozi RF ka ọ bụrụ mgbama ọkụ eletrik.

Ọgụgụ 1 Isi Nhazi nke ahịrị igbu oge Optic Fiber OFDL

Ngwa ndapụta
1.Phased array radar: Akụkụ bụ isi nke radar array akpụ akpụ bụ antenna n'usoro nhazi. Antenna radar ọdịnala adịghị anya na-emezu ihe achọrọ nke sistemu radar, ebe ahịrị igbu oge fiber optic nwere uru arụmọrụ ha pụrụ iche na ntinye nke antennas nhazi usoro. Ya mere, ahịrị igbu oge nke fiber optic nwere mkpa sayensị pụtara na radar n'usoro nhazi oge.
2.Fiber optic nkwurịta okwu usoro: Fiber optic ahịrị nwere ike iji mejuputa atumatu nzuzo. Site n'iwebata oge dị iche iche n'oge dị iche iche, enwere ike ịmepụta akara ngosi nwere usoro dị iche iche, nke bara uru maka ịkwalite ikike mgbochi nnyonye anya nke mgbaàmà na usoro nkwurịta okwu dijitalụ. Na mgbakwunye, enwere ike iji ya dị ka nchekwa nwa oge (cache) iji chekwaa ụfọdụ data nwa oge, na ihe ndị ọzọ. Na nkenke, ahịrị igbu oge fiber optic nwere ọtụtụ ngwa n'ọtụtụ mpaghara n'ihi nnukwu bandwidth ha, mfu dị ala, yana iguzogide nnyonye anya elektrọn. Ma na ngalaba nzikọrịta ozi, radar, ịnyagharị, ma ọ bụ onyonyo ahụike, ha niile na-arụ ọrụ dị mkpa.
