Kazhinji, simba rinopenya re optical fiber transceiver kana optical module ndeyotevera: multimode iri pakati pe10db uye -18db; single mode is 20km between -8db and -15db; uye single mode is 60km iri pakati -5db ne -12db pakati. Asi kana simba rinopenya refiber optic transceiver richionekwa pakati pe -30db uye -45db, zvino zvingangoita kuti iyi fiber optic transceiver ine dambudziko.
Nzira yekutonga sei kana pane dambudziko ne fiber optic transceiver?
(1) Chekutanga, ona kana chiratidzo chechiedza che optical fiber transceiver kana optical module uye mwenje wechiratidzo cheyakamonyoroka pair port chiri pa
a. Kana iyo FX chiratidzo cheiyo transceiver yakadzimwa, ndapota simbisa kana iyo fiber link yakabatana-yakabatana? Imwe mugumo wefiber jumper inobatanidzwa mukufanana; mumwe mugumo wakabatanidzwa mumuchinjikwa mode.
b. Kana iyo optical port (FX) chiratidzo cheA transceiver iripo uye optical port (FX) chiratidzo cheB transceiver chadzimwa, mhosva iri paA transceiver side: imwe mukana ndeye: A transceiver (TX) optical transmission chiteshi chakashata nokuti optical port (RX) yeB transceiver haigamuchire chiratidzo chemaziso; imwe nzira ndeye: pane dambudziko neiyi fiber link yeaptical transmission port yeA transceiver (TX) (iyo optical cable kana jumper yemaziso inogona kutyorwa).
c. Iyo twisted pair (TP) chiratidzo chadzimwa. Ndokumbira uve nechokwadi chekuti twisted pair connection haina kunaka kana kuti kubatana kwacho kwakaipa? Ndapota shandisa muongorori wekuenderera mberi kuti uedze (zvisinei, mwenje wakamonyoroka wemamwe ma transceivers anofanira kumirira kusvikira fiber link yabatanidzwa).
d. Mamwe ma transceivers ane maviri maRJ45 ports: (ToHUB) inoratidza kuti mutsetse wekubatanidza kunechinjamutsetse wakatwasuka; (ToNode) inoratidza kuti mutsara wekubatanidza kunechinjairi crossover line.
e. Mamwe ekuwedzera bvudzi ane MPRchinjapadivi: zvinoreva kuti tambo yekubatanidza kunechinjamutsetse wakatwasuka; DTEchinja: mutsara wekubatanidza kunechinjais a cross-over mode.
(2) Kana tambo ye optical uye optical fiber jumper zvatyoka
a. Optical tambo yekubatanidza uye kuona kwekubvisa: shandisa laser tochi, chiedza chezuva, muviri unopenya kuvhenekera imwe magumo eiyo optical tambo yekubatanidza kana coupling; kuona kana kune chiedza chinooneka kune rumwe rutivi? Kana pane chiedza chinooneka, chinoratidza kuti optical cable haina kuputsika.
b. On-off kuonekwa kwe optical fiber connection: shandisa laser tochi, chiedza chezuva, nezvimwewo kuvhenekera imwe mugumo we fiber jumper; kuona kana kune chiedza chinooneka kune rumwe rutivi? Kana pane chiedza chinooneka, fiber jumper haina kuputsika.
(3) Kunyangwe iyo hafu / yakazara duplex modhi isiriyo
Mamwe ma transceivers ane FDXswitchesparutivi: duplex yakazara; HDXswitches: hafu duplex.
(4) Edza ne optical simba mita
Simba rinopenya re optical fiber transceiver kana optical module pasi pemamiriro ezvinhu akajairika: multi-mode: pakati -10db uye -18db; single-mode makiromita makumi maviri: pakati -8db uye -15db; imwe-modhi 60 makiromita: pakati -5db uye -12db; Kana simba rinopenya refiber optic transceiver riri pakati -30db-45db, zvino inogona kutongwa kuti pane dambudziko neiyi fiber optic transceiver.
