    Kedu otu esi ekpe ikpe ma enwere nsogbu na transceiver fiber optic?

    Oge nzipu: Jun-09-2020

    N'ozuzu, ike ọkụ nke transceiver fiber optic ma ọ bụ modul anya bụ nke a: multimode dị n'etiti 10db na -18db; otu ọnọdụ bụ 20km n'etiti -8db na -15db; na otu mode bụ 60km bụ n'etiti -5db na -12db n'etiti. Ma ọ bụrụ na ike ọkụ nke eriri optic transceiver pụtara n'etiti -30db na -45db, mgbe ahụ ọ ga-abụ na nke a fiber optic transceiver nwere nsogbu.

    Kedu otu esi ekpe ikpe ma enwere nsogbu na transceiver fiber optic?

    (1) Nke mbụ, hụ ma ọ bụrụ na ọkụ egosi nke transceiver fiber optical ma ọ bụ modul anya na ọkụ egosi nke ọdụ ụgbọ mmiri gbagọrọ agbagọ agbanyere.

    a. Ọ bụrụ na ihe ngosi FX nke transceiver agbanyụrụ, biko gosi na njikọ eriri ejikọrọ? A na-ejikọta otu njedebe nke jumper fiber n'otu n'otu; A na-ejikọta njedebe nke ọzọ na ọnọdụ cross.

    b. Ọ bụrụ na egosi ọdụ ụgbọ mmiri anya (FX) nke A transceiver dị na ọdụ anya ọdụ ụgbọ mmiri (FX) egosi nke transceiver B, mmejọ ahụ dị n'akụkụ A transceiver: otu ohere bụ: A transceiver (TX) ngwa anya nnyefe The transceiver ọdụ ụgbọ mmiri dị njọ n'ihi na ọdụ ụgbọ mmiri anya (RX) nke transceiver B anaghị enweta akara ngosi anya; ihe ọzọ nwere ike ime bụ: enwere nsogbu na njikọ eriri a nke ọdụ ụgbọ mmiri anya nke transceiver A (TX) (igwe anya ma ọ bụ jumper ngwa anya nwere ike ịgbaji).

    c. Ihe nrịbama gbagọrọ agbagọ (TP) agbanyụrụ. Biko hụ na njikọ abụọ gbagọrọ agbagọ ezighi ezi ma ọ bụ njikọ ahụ adịghị mma? Biko jiri ihe nleba anya na-aga n'ihu iji nwalee (agbanyeghị, ọkụ na-egosi ụzọ gbagọrọ agbagọ nke ụfọdụ transceivers ga-echere ruo mgbe ejikọrọ eriri eriri).

    d. Ụfọdụ transceivers nwere ọdụ ụgbọ mmiri RJ45 abụọ: (ToHUB) na-egosi na eriri njikọ naịgbanweebụru ngwẹja-ododo; (ToNode) na-egosi na ahịrị njikọ naịgbanweebụ eriri ngafe.

    e. Ụfọdụ ndọtị ntutu nwere MPRịgbanween'akụkụ: ọ pụtara na njikọ njikọ naịgbanweebụru ngwẹja-ododo; DTEịgbanwee: eriri njikọ naịgbanweebụ a cross-over mode.

    (2) Ma agbajiwo eriri anya na eriri anya

    a. Njikọ eriri anya na nchọpụta nkwụsị: jiri ọkụ ọkụ laser, ìhè anyanwụ, ahụ na-egbuke egbuke na-amụnye otu njedebe nke njikọ eriri anya ma ọ bụ njikọ; lee ma enwere ìhè a na-ahụ anya na nsọtụ nke ọzọ? Ọ bụrụ na enwere ọkụ a na-ahụ anya, ọ na-egosi na eriri anya adịghị agbaji.

    b. Nchọpụta na-apụ apụ nke njikọ eriri anya: jiri ọkụ ọkụ laser, ìhè anyanwụ, wdg iji mee ka otu njedebe nke eriri jumper pụta ìhè; hụ ma ọ bụrụ na enwere ìhè a na-ahụ anya na nsọtụ nke ọzọ? Ọ bụrụ na enwere ìhè a na-ahụ anya, eriri jumper adịghị agbaji.

    (3) Ma ọkara/duplex mode ọ na-ezighị ezi

    Ụfọdụ transceivers nwere FDXmgba ọkụn'akụkụ: zuru duplex; HDXmgba ọkụ: ọkara duplex.

    (4) Jiri mita ike anya nwalee

    Ike na-egbuke egbuke nke transceiver fiber optic ma ọ bụ modul anya n'okpuru ọnọdụ nkịtị: multi-mode: n'etiti -10db na -18db; otu ụdị 20 kilomita: n'etiti -8db na -15db; otu ụdị 60 kilomita: n'etiti -5db na -12db; Ọ bụrụ na ike ọkụ nke eriri optic transceiver dị n'etiti -30db-45db, mgbe ahụ enwere ike ikpebi na enwere nsogbu na transceiver fiber optic a.
