Mgbe ọrụ ndị na-adịghị ike ugbu a na-ezute nnyefe dị anya, a na-ejikarị fiber optics eme ihe. N'ihi na nnyefe anya nke eriri anya dị ogologo, n'ozuzu, nnyefe nke eriri otu mode karịrị 10 kilomita, na nnyefe nke multi-mode eriri nwere ike iru ruo 2 kilomita.
Na netwọk fiber optic, anyị na-ejikarị transceivers fiber optic. Yabụ, otu esi ejikọ transceivers fiber optic? Ka anyị lee ọnụ anya.
Nke mbụ, ọrụ nke transceivers fiber optic
① Ihe ntụgharị eriri anya nwere ike ịgbatị ebe nnyefe nke Ethernet ma gbasaa radius mkpuchi nke Ethernet.
② Ihe transceiver eriri anya nwere ikeịgbanween'etiti 10M, 100M ma ọ bụ 1000M Ethernet interface eletriki na ngwa anya interface.
③ Iji transceivers fiber optic wulite netwọk nwere ike ịchekwa ego netwọkụ.
④ Ndị transceivers fiber optical na-eme ka njikọ dị n'etiti sava, ndị na-emegharị ihe, ọdụ, ọnụ na ọnụ ọnụ ngwa ngwa.
⑤ transceiver fiber optical nwere microprocessor na interface nyocha, nke nwere ike ịnye ozi arụmọrụ njikọ data dị iche iche.
Nke abụọ, nke transceiver ka transceiver anya nwere na nke ọ na-enweta?
Mgbe ị na-eji transceivers fiber optical, ọtụtụ ndị enyi ga-ezute ajụjụ ndị dị otú ahụ:
1.Do optical fiber transceivers ga-eji na abụọ?
2.Ọ bụ transceiver optical fiber transceiver kewara n'ime otu maka ịnata na otu maka ịnyefe? Ma ọ bụ enwere ike iji naanị transceivers anya abụọ dị ka ụzọ abụọ?
3. Ọ bụrụ na a ga-eji transceivers fiber optic transceivers mee ihe na abụọ, ọ dị mkpa na ha bụ otu ụdị na ụdị? Ma ọ bụ enwere ike iji ụdị ọ bụla na ngwakọta?
Azịza: A na-ejikarị transceivers fiber optic transceivers na ụzọ abụọ dị ka ngwaọrụ ntụgharị fotoelectric, mana ọ ga-ekwe omume ijikọ transceivers fiber optic na eriri.mgba ọkụ, eriri optic transceivers na SFP transceivers. Na ụkpụrụ, ọ bụrụhaala na ngwa anya nnyefe wavelength bụ otu Usoro encapsulation mgbaàmà bụ otu ma na-akwado a ụfọdụ protocol iji nweta ngwa anya fiber nkwurịta okwu.
N'ozuzu, otu mode dual-fiber (a na-achọ eriri abụọ maka nkwurịta okwu nkịtị) anaghị ekewa transceivers na njedebe na-ebufe na njedebe nnata, a pụkwara iji ya mee ihe ma ọ bụrụhaala na ha pụtara na abụọ.
Naanị transceiver otu-fiber (otu eriri achọrọ maka nkwurịta okwu nkịtị) ga-enwe njedebe na-ebufe na njedebe nnata.
N'ikwu ya n'ụzọ ọzọ, ọnụego dị iche iche (100M na Gigabit) na ogologo wavelength dị iche iche (1310nm na 1300nm) enweghị ike ịkparịta ụka n'etiti ibe ha. Tụkwasị na nke ahụ, ọ bụrụgodị na otu eriri transceiver na eriri abụọ nke otu ika na-ejikọta, ọ gaghị ekwe omume ịkọrọ ibe ha. Enwere ike imekọrịta ihe.
Ya mere, ajụjụ bụ, kedu otu eriri transceiver na ihe bụ dual fiber transceiver? Kedu ihe dị iche n'etiti ha?
Kedu ihe bụ transceiver otu-fiber? Kedu ihe bụ transceiver dual-fiber?
Otu transceiver fiber na-ezo aka na eriri anya otu ụdị. Ihe transceiver otu-fiber na-eji naanị otu isi na njedebe abụọ jikọtara ya na isi a. Ndị transceivers na nsọtụ abụọ ahụ na-eji ogologo ikuku anya dị iche iche, yabụ enwere ike ibunye ha n'otu mgbama ọkụ isi.
Igwe transceiver dual-fiber na-eji cores abụọ, otu maka nnyefe na otu maka nnabata, na otu njedebe ga-etinyerịrị na nsọtụ nke ọzọ, a ga-agafekwa nsọtụ abụọ ahụ.
1. Single eriri transceiver
Otu transceiver fiber ga-emejuputa ma ọrụ nnyefe yana ọrụ nnata. Ọ na-eji teknụzụ multiplexing nkewa wavelength iji nyefee ma nata akara ngosi anya abụọ nwere ogologo ogologo ogologo dị iche iche n'otu eriri anya.
Ya mere, otu-mode otu-fiber transceiver na-ebufe site na isi eriri anya, ya mere a na-ebufe na-ebufe na ịnweta ìhè site na eriri eriri n'otu oge. N'okwu a, iji nweta nzikọrịta ozi nkịtị, a ga-eji ogologo wavelength nke ìhè dị iche iche.
Ya mere, modul ngwa anya nke otu-mode otu-fiber transceiver nwere ogologo wavelength abụọ nke ìhè emitted, na-abụkarị 1310nm / 1550nm. N'ụzọ dị otú a, e nwere ọdịiche dị n'etiti nsọtụ abụọ nke ụzọ transceivers:
Onye ntụgharị n'otu njedebe na-ebufe 1310nm wee nata 1550nm.
Ngwugwu ọzọ na-ebunye 1550nm na ịnweta 1310nm.
Yabụ na ọ dị mma maka ndị ọrụ ịmata ọdịiche, na iji mkpụrụedemede na-ejikarị.
A-ọnụ (1310nm / 1550nm) na B-ọnụ (1550nm / 1310nm) pụtara.
Ndị ọrụ ga-ejiri njikọ AB, ọ bụghị njikọ AA ma ọ bụ BB.
A na-eji njedebe AB naanị maka otu transceivers fiber optic.
2.Dual eriri transceiver
The dual-fiber transceiver nwere ọdụ ụgbọ mmiri TX (ọdụ ụgbọ mmiri na-ebufe) na ọdụ ụgbọ mmiri RX (ọdụ ụgbọ mmiri na-anata). Ọdụ ụgbọ mmiri abụọ ahụ na-ebufe n'otu ogologo ogologo nke 1310nm, nnabata ahụ bụkwa 1310nm. Ya mere, eriri anya abụọ yiri nke a na-eji na wiring na-ejikọta ya.
3. Olee otú ịmata ọdịiche otu eriri transceiver si dual eriri transceiver?
Enwere ụzọ abụọ ugbu a iji mata ọdịiche transceivers otu-fiber na transceivers dual-fiber transceivers.
① Mgbe a na-etinye transceiver ngwa anya na modul ngwa anya, a na-ekewa transceiver anya n'ime otu transceiver otu-fiber transceiver na transceiver dual-fiber dị ka ọnụ ọgụgụ nke cores nke eriri ihe eji eme ihe ejikọrọ. The linearity nke optical fiber jumper ejikọrọ na otu-fiber transceiver (n'aka nri) bụ eriri isi, nke na-ahụ maka ma na-ebufe na ịnata data; Linearity bụ isi abụọ. Otu isi bụ ọrụ maka ịnyefe data na isi nke ọzọ bụ maka ịnata data.
② Mgbe transceiver optical fiber transceiver enweghị modul ngwa anya agbakwunyere, ọ dị mkpa ịmata ọdịiche dị n'etiti otu transceiver fiber transceiver na transceiver fiber dual dị ka modul optical etinyere si dị. Mgbe etinyere otu-fiber optical optical modul n'ime transceiver optical fiber transceiver, ya bụ, interface bụ ụdị simplex, transceiver optical fiber transceiver bụ otu-fiber transceiver (foto ziri ezi); mgbe etinyere modul optical bidirectional optical modul n'ime transceiver optical fiber transceiver, Ya bụ, mgbe interface ahụ bụ ụdị duplex, transceiver a bụ transceiver dual-fiber (foto aka ekpe).
