3, iji transceiver fiber optical iji wuo netwọkụ nwere ike ịchekwa ego netwọkụ.
4. Fiber optic transceiver na-eme ka njikọ dị n'etiti sava, repeater, hub, terminal na terminal rụọ ọrụ nke ọma.
5, eriri transceiver nwere microprocessor na diagnostic interface, nwere ike ịnye ozi arụmọrụ njikọ data dị iche iche.
2. Kedu nke na-ebupụta ma ọ bụ nke na-enweta transceiver fiber-optic?
Mgbe ị na-eji transceiver fiber optical, ọtụtụ ndị enyi ga-ezute ajụjụ dị otú ahụ:
1. Ekwesịrị iji transceiver optic fiber optic transceiver ụzọ abụọ?
2, transceiver optical fiber transceiver enweghị isi, otu ga-enweta otu bụ izipu? Ma ọ bụ enwere ike iji transceivers fiber abụọ dị ka ụzọ abụọ?
3. Ọ bụrụ na a ga-eji transceiver fiber optical na ụzọ abụọ, otu ụzọ ga-abụ otu akara na ihe nlereanya? Ma ọ bụ ị nwere ike iji ngwakọta ọ bụla nke ika ọ bụla?
Ọtụtụ ndị enyi nwere ike inwe ajụjụ a na usoro nke oru ngo, ya mere gịnị ka ọ bụ? Azịza: ngwa anya eriri transceiver dị ka fotoelectric ntughari akụrụngwa na-ejikarị na-eji abụọ abụọ, ma nwekwara ike ịpụta ngwa anya fiber transceiver na ngwa anya eriri mgba ọkụ, ngwa anya eriri transceiver na SFP transceiver pairing ojiji bụkwa ihe nkịtị, ụkpụrụ, ọ bụrụhaala na ngwa anya nnyefe wavelength bụ nkịtị. otu, mgbaàmà encapsulation format bụ otu na-akwado ụfọdụ protocol nwere ike na-aghọta ngwa anya eriri nkwurịta okwu. General otu mode okpukpu abụọ eriri (nkịtị nzikọrịta chọrọ abụọ eriri) transceiver bụ n'agbanyeghị nke transmitter na-enweta ọgwụgwụ, ọ bụrụhaala na ụzọ nwere ike ji mee ihe. Naanị otu transceiver fiber (nkwukọrịta nkịtị chọrọ eriri) ga-enwe njedebe nnyefe dị iche na njedebe nnabata.
Ma ọ bụ transceiver eriri okpukpu abụọ ma ọ bụ otu eriri transceiver ka a ga-eji ụzọ abụọ, ụdị dị iche iche nwere ike dakọtara na interoperability. Mana ọnụego, ogologo wavelength na ụkpụrụ bụ otu. Ya bụ, dị iche iche ọnụego (100 na gigabit), dị iche iche wavelengths (1310nm na 1300nm) na-enweghị ike na-ekwurịta okwu na onye ọ bụla ọzọ, na mgbakwunye, ọbụna otu ika nke otu eriri transceiver na okpukpu abụọ eriri ụdị a ụzọ na-adịghị jikọrọ ọnụ. Ya mere, ajụjụ bụ, kedu otu eriri transceiver, na ihe bụ abụọ fiber transceiver? Kedu ihe dị iche n'etiti ha?
3. Gịnị bụ otu-fiber transceiver? Kedu ihe bụ transceiver eriri abụọ?
Otu transceiver fiber transceiver na-ezo aka n'iji eriri igwe anya nke otu mode, otu eriri transceiver bụ naanị isi, a na-ejikọ akụkụ abụọ ahụ na isi, ma nsọtụ nke transceiver na-eji ogologo ogologo ọkụ dị iche iche, yabụ na ọ nwere ike ibunye mgbaàmà ọkụ na isi. Ugboro abụọ eriri transceiver bụ ojiji nke abụọ isi, a na-eziga a na-enweta, otu njedebe bụ ntutu isi, nke ọzọ na njedebe ga-etinyere n'ọdụ ụgbọ mmiri, bụ abụọ nsọtụ gafere.
1, otu eriri transceiver
Otu transceiver fiber kwesịrị ịghọta ma ọrụ nnyefe yana ọrụ nnata. Ọ na-eji teknụzụ multiplexing nkewa ebili mmiri na-ebufe akara ngosi anya abụọ nke ogologo wavelength dị iche iche na eriri anya iji ghọta nnyefe na nnabata.
Ya mere, a na-ebufe transceiver otu-mode otu-fiber site na eriri, ya mere a na-ebufe na-ebufe na ịnweta ìhè site na eriri eriri n'otu oge ahụ. N'okwu a, a ghaghị iji ebili mmiri abụọ nke ìhè mee ihe iji nweta nkwurịta okwu nkịtị.
Ya mere, modul ngwa anya nke otu-mode otu-fiber transceivers nwere oghere anya abụọ, n'ozuzu 1310nm / 1550nm, yabụ njedebe abụọ nke ụzọ transceivers ga-adị iche. transceiver otu njedebe na-ebufe 1310nm wee nata 1550nm. N'akụkụ nke ọzọ, ọ na-ewepụta 1550nm wee nata 1310nm. Ya mere adaba maka ndị ọrụ ịmata ọdịiche, n'ozuzu ga-eji mkpụrụedemede kama. Ọgwụgwụ A (1310nm / 1550nm) na njedebe B (1550nm / 1310nm) pụtara. Ndị ọrụ ga-ejikọta AB iji jiri, ọ bụghị njikọ AA ma ọ bụ BB. AB na-eji naanị otu eriri transceiver.
2, transceiver eriri abụọ
Ihe transceiver eriri okpukpu abụọ nwere ọdụ ụgbọ mmiri TX (ọdụ ụgbọ mmiri na-ebufe) na ọdụ ụgbọ mmiri RX (ọdụ ụgbọ mmiri na-anata). Abụọ ọdụ ụgbọ mmiri nwere otu wavelength nke 1310nm, na n'ikuku bụ 1310nm, n'ihi ya, abụọ yiri eriri anya eriri na-eji maka cross njikọ.
3, otu esi amata ọdịiche nke transceiver otu fiber na transceiver eriri abụọ
Enwere ụzọ abụọ iji mata ọdịiche nke transceivers otu fiber na transceivers fiber abụọ.
① Mgbe a na-etinye transceiver optical fiber transceiver na modul ngwa anya, a na-ekewa transceiver optical fiber transceiver n'ime otu transceiver fiber transceiver na transceiver fiber abụọ dị ka ọnụ ọgụgụ nke eriri jumper optical jikọtara ọnụ. Otu eriri transceiver (n'aka nri) jikọtara ya na eriri fiber, nke na-ahụ maka ịnyefe data na ịnata data, ebe transceiver fiber abụọ (aka ekpe) jikọtara ya na eriri eriri abụọ, otu n'ime ha na-ahụ maka ịnyefe data na ndị ọzọ na-ahụ maka ịnata data.
② Mgbe transceiver optical fiber transceiver enweghị modul ngwa anya agbakwunyere, ọ dị mkpa ịmata ọdịiche ma ọ bụ transceiver fiber otu ma ọ bụ transceiver fiber dual dị ka ihe ntinye anya etinyere. Mgbe etinyere transceiver fiber optical na otu fiber bidirectional optical module, ya bụ, interface bụ otu ụdị, transceiver fiber a (nri); mgbe etinyere eriri transceiver na eriri eriri abụọ nke eriri anya, ma ọ bụ interface ahụ bụ ụdị duplex, transceiver bụ transceiver eriri okpukpu abụọ (ọnụọgụ aka ekpe).
