Ob qhov tseem ceeb rau kev siv optical modules

Nco ntsoov tias ob lub ntsiab lus hauv qab no tuaj yeem pab koj txo qhov poob ntawm qhov kho qhov muag module thiab txhim kho qhov ua tau zoo ntawm qhov kho qhov muag module.

Nco tseg 1:

1. Muaj cov khoom siv CMOS hauv cov nti no, yog li ua tib zoo saib xyuas kom tsis txhob muaj hluav taws xob zoo li qub thaum thauj thiab siv.
2. Cov cuab yeej yuav tsum tau grounded zoo kom txo tau cov kab mob parasitic inductance.
3. Try rau solder los ntawm txhais tes, yog tias koj xav tau lub tshuab stickers, tswj reflow kub tsis pub tshaj 205 degrees Celsius.
4. Tsis txhob nteg tooj liab nyob rau hauv lub optical module tiv thaiv impedance hloov.
5. Lub kav hlau txais xov yuav tsum tau muab cia kom deb ntawm lwm lub voj voog kom tsis txhob muaj hluav taws xob ua kom tsis muaj zog los yog cuam tshuam rau kev siv ntawm lwm cov circuits.
6. Module kev tso kawm yuav tsum nyob deb li deb li sai tau los ntawm lwm yam tsawg zaus circuits, digital circuits.
7. Nws raug nquahu kom siv cov hlaws sib nqus rau kev sib cais ntawm cov khoom siv hluav taws xob.

Lus Cim 2:

1. Koj tsis tuaj yeem saib ncaj qha rau ntawm qhov kho qhov muag module (txawm mus deb lossis luv-ntau qhov kho qhov muag module) uas tau ntsaws rau hauv lub cuab yeej kom tsis txhob mob qhov muag.
2. Nrog rau qhov ntev ntawm qhov kho qhov muag module, lub zog hluav taws xob xa hluav taws xob feem ntau ntau dua li lub hwj chim kho qhov muag overload. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov ntev ntawm qhov kho qhov muag fiber ntau kom ntseeg tau tias qhov tseeb tau txais lub hwj chim kho qhov muag tsawg dua lub hwj chim kho qhov muag overload. Yog hais tias qhov ntev ntawm qhov kho qhov muag fiber ntau yog luv luv, koj yuav tsum tau siv qhov ntev-ntev kho qhov muag module los koom tes nrog cov kho qhov muag attenuation. Ceev faj tsis txhob hlawv lub optical module.
3. Txhawm rau tiv thaiv kev tu kom zoo ntawm qhov kho qhov muag module, nws raug nquahu kom ntsaws cov plua plav ntsaws thaum tsis siv. Yog hais tias cov optical contacts tsis huv, nws yuav cuam tshuam rau lub teeb liab zoo thiab yuav ua rau muaj teeb meem txuas thiab me ntsis yuam kev.
4. Lub optical module feem ntau yog cim nrog Rx / Tx, los yog ib tug xub nyob rau hauv thiab tawm los pab qhia txog tus transceiver. Tx ntawm ib kawg yuav tsum txuas nrog Rx ntawm lwm qhov kawg, txwv tsis pub ob qhov kawg tsis tuaj yeem txuas.
