Akụkọ - Waveband maka eriri anya

Nzikọrịta eriri anya na-ewere ìhè dị ka onye na-ebu ozi iji kparịta ụka.Enwere ike ibunye ya site na eriri fiber.Otú ọ dị, ọ bụghị ọkụ ọkụ ọ bụla kwesịrị ekwesị maka nkwurịta okwu.Ọnwụ nnyefe na-adịgasị iche na eriri ọkụ dị iche iche.Maka inweta obere mfu na ịdị na-arụ ọrụ nke ọma, ndị ọkà mmụta sayensị na-achọ mgbe niile ọkụ kachasị mma.

850nm Waveband

Na mmalite 1980s, ndị ọkà mmụta sayensị malitere inyocha teknụzụ nke nkwurịta okwu fiber anya n'ụzọ bara uru.Multi-mode eriri bụ ihe ha na-amụkarị maka ya.Na nnukwu eriri eriri, muti-mode eriri na-enwe ike ịghọta otu nnyefe eriri maka ọkụ muti-mode.850nm wavelength ìhè bụ nke etinyere na mbụ.

O Waveband

Ná mmalite nke 1990s, a malitere iji eriri otu ụdị eme ihe n'ọtụtụ ebe.

Onyonyo 1

Ndị ọkà mmụta sayensị chọpụtara na 1260nm ~ 1360nm waveband ìhè nwere ike nweta mgbagha mgbaàmà kachasị nta na nkwụsị nnyefe nke kpatara mgbasa site na ule. N'ihi ya, ha kpọrọ ndị a waveband ìhè dị ka O-band na "O" pụtara "Original".Na ule na njehie, ndị ọkà mmụta sayensị chọpụtara na ìhè na 1260nm ~ 1625nm dịkwa na mpaghara ọnwụ kacha nta ma bụrụ ìhè kachasị mma maka nnyefe eriri.

1260nm ~ 1625nm waveband ọkụ na-ekewa n'ime ise-O waveband, E waveband, S waveband, C waveband na L waveband.

Ndị ọkà mmụta sayensị chọpụtakwara njikọ dị n'etiti mfu nnyefe na ogologo ogologo.Ọ na-egosi dị ka ndị a.

Onyonyo 3

Ihe nke a na-ejikarị eme ihe bụ C waveband ((1530nm ~ 1565nm), nke na-anọchite anya "conventional".C band nwere ike nweta ihe kacha nta nnyefe ọnwụ nke a na-etinyere n'ọtụtụ ebe na MAN, ogologo anya, ultra ogologo anya, okpuru mmiri ngwa anya cable sistem na WDM usoro.

L Waveband (1565nm ~ 1625nm)

L na-anọchi anya "ogologo ogologo ogologo".L waveband nwere ike nweta mfu nnyefe kacha nta nke abụọ yana bụkwa otu n'ime nhọrọ kachasị maka ụlọ ọrụ.Ọ bụrụ na C waveband enweghị ike igbo mkpa bandwit, ndị mmadụ na-ewerekarị L waveband dị ka ihe mgbakwunye.

S Waveband (1460nm ~ 1530nm)

S na-anọchi anya "obere ogologo ogologo".A bịa na mfu fiber, ọ dị elu karịa O waveband.A na-etinyekarị ya na ebili mmiri ala PON.

E Waveband

Ọ bụ eriri ebili mmiri na-adịkarịkarị n'etiti ụdị ebili mmiri ise.E na-anọchi anya “gbatịa.” Dị ka e gosiri na foto nke 3, a na-ahụ mpụta n'elu E waveband.Nke ahụ bụ n'ihi na OH na-etinye ya n'ahụ - nke na-eduga na nnukwu mfu nnyefe, nke a na-akpọkwa ọnụ mmiri mmiri.

Laa azụ n'oge ochie, n'ihi teknụzụ nwere oke, a na-agwakọta mmiri na enyo fiber optic nke butere nnukwu mfu nnyefe na E waveband na ọ nweghị ike ịrụ ọrụ nke ọma.Mgbe nke ahụ gasịrị, ndị mmadụ mepụtara teknụzụ ịkpọ nkụ n'ime iko, kemgbe ahụ, mfu nnyefe na E waveband dị obere karịa O waveband.Agbanyeghị, ọnwụ nnyefe mere na E waveband na eriri eriri anya nke edobere tupu nke ahụ kọwara na a ka nwere oke maka E waveband etinyere na nkwukọrịta fiber optical.
