Nkhani zinayi zomwe zingatheke komanso zodzitetezera pakugwiritsa ntchito ma module a kuwala

Monga chigawo chapakati cha machitidwe owonetsera optical, ma modules optical amagwirizanitsa zigawo zenizeni za kuwala ndi zozungulira mkati, zomwe zimapangitsa kuti zikhale zovuta kwambiri kulandira ndi kutumiza zizindikiro za kuwala. Nkhaniyi ikufotokoza mavuto omwe ma modules optical angakumane nawo panthawi yogwiritsira ntchito, komanso zodzitetezera zomwe tiyenera kusamala nazo, kuti tiwonjezere moyo wautumiki wa ma modules optical ndikuwongolera ntchito zawo.

1. Optical doko kuipitsa / kuwonongeka

Kuwonongeka kwa doko la Optical kungayambitse kuchepetsedwa kwa ma siginecha owoneka, zomwe zimapangitsa kusokonekera kwa ma siginecha ndi kuchuluka kwa zolakwika pang'ono, zomwe zimakhudza kufalikira kwa ma module optical, makamaka ma module atalitali opatsira optical, omwe amatha kukhudzidwa kwambiri ndi doko la kuwala. kuipitsa.

Pali zifukwa ziwiri zazikulu zakuipitsa ma port:

①Mawonekedwe owoneka bwino amawululidwa ndi mpweya kwa nthawi yayitali. - Mawonekedwe owoneka bwino a module ya Optical ayenera kukhala oyera. Ngati atawululidwa ndi mpweya kwa nthawi yayitali, padzakhala fumbi lambiri mu gawo la optical, kutsekereza doko la kuwala, motero zimakhudza kufalikira kwabwino kwa ma sign optical;

②Gwiritsani ntchito ma jumper otsika optical fiber - Kugwiritsa ntchito ma jumper otsika optical fiber kumatha kuwononga zinthu zomwe zili mkati mwa doko la kuwala. Mawonekedwe owoneka bwino a module ya optical amatha kuipitsidwa pakuyika ndikuchotsa.

Chifukwa chake, ndikofunikira kuchita ntchito yabwino yopewera fumbi ndikugwiritsa ntchito ma jumper apamwamba kwambiri!

2. ESDElectro-Static discharge） kuwonongeka

Magetsi osasunthika ndi cholinga chachilengedwe, chopangidwa m'njira zambiri, monga kukhudzana, kukangana, kulowetsedwa pakati pa zida zamagetsi, etc. Magetsi osasunthika amadziwika ndi kudzikundikira kwanthawi yayitali, voteji yayikulu, magetsi otsika, ang'onoang'ono apano komanso nthawi yayitali.

Kuwonongeka kwa ESD kwa ma module a kuwala:

①ESD magetsi osasunthika amatenga fumbi, amatha kusintha kutsekeka pakati pa mizere, kukhudza magwiridwe antchito ndi moyo wa gawo la kuwala;

②Kutentha kopangidwa ndi magetsi a ESD nthawi yomweyo kapena zamakono za ESD zidzawononga zigawozo, ndipo mawonekedwe afupipafupi a Optical module amatha kugwirabe ntchito, koma adzakhudzabe moyo wake;

③ESD imawononga kusungunula kapena kokondakita wa chigawocho ndikuwononga kwathunthu gawo la kuwala.

Magetsi osasunthika atha kunenedwa kuti amapezeka paliponse m'moyo wathu watsiku ndi tsiku, ndipo timanyamula ma voltages apamwamba a electrostatic ndi kuzungulira ife, kuyambira ma volts masauzande angapo mpaka makumi masauzande a volts. Mwina sindingadziwe kuti magetsi osasunthika omwe amapangidwa poyenda pamakapeti opangidwa amakhala pafupifupi 35000 volts, pomwe kuwerenga mabuku apulasitiki ndi pafupifupi 7000 volts. Kwa zida zina zomvera, mphamvuyi imatha kukhala yowopsa! Chifukwa chake, njira zodzitchinjiriza (monga matumba odana ndi static, ma wristband a anti-static, magolovesi oletsa kukhazikika, zovundikira zala zala, zovala za anti-static, manja oletsa static, etc.) ziyenera kutengedwa posunga/ kunyamula / kugwiritsa ntchito gawo la optical, ndikulumikizana mwachindunji ndi optical module ndikoletsedwa!

3.Kuvulala kwa Goldfinger

Chala chagolide ndi cholumikizira cholowetsa ndikuchotsa gawo la kuwala. Zizindikiro zonse za module ya optical ziyenera kufalitsidwa ndi chala chagolide. Komabe, chala cha golide chikuwonekera mu chilengedwe chakunja kwa nthawi yaitali, ndipo n'zosavuta kuwononga chala cha golide ngati module ya optical sichigwiritsidwa ntchito bwino.

Chifukwa chake, kuti muteteze Goldfinger, chonde tcherani khutu ku mfundo ziwiri izi:

① Osachotsa chivundikiro choteteza panthawi yoyendetsa ndikusungira gawo la Optical.

②Musakhudze chala chagolide cha module ya optical ndikuchigwira mofatsa kuti muteteze module ya optical kuti isakanikizidwe kapena kugwedezeka. Ngati gawo la optical lidagundidwa mwangozi, musagwiritsenso ntchito mawonekedwe a Optical.

4.Mawonekedwe akutali optical module sagwiritsidwa ntchito bwino

Monga momwe zimadziwika bwino, tikamagwiritsa ntchito ma modules optical, tiyenera kuonetsetsa kuti mphamvu yeniyeni yolandira kuwala imakhala yocheperapo kusiyana ndi mphamvu yowonjezera yowonjezera. Chifukwa chakuti mphamvu yotumizira kuwala kwa ma module akutali kwambiri imakhala yayikulu kuposa mphamvu yamagetsi yodzaza, ngati kutalika kwa fiber ndi kochepa, ndikothekera kuwotcha gawo la optical.

Choncho, tiyenera kumamatira mfundo ziwiri zotsatirazi:

①Mukagwiritsa ntchito mawonekedwe opangira, chonde werengani zofunikira zake kaye ndipo musalumikizane ndi fiber optic nthawi yomweyo;

②Osayesa kuyesa kwa loop back pa module yotalikirapo nthawi iliyonse. Ngati mukuyenera kuyesa kuyesa kumbuyo kwa loop, igwiritseni ntchito ndi optical fiber attenuator.

Sandao Technology imapereka njira zolumikizirana zowoneka bwino monga ma data center ndi ma network abizinesi. Ngati mukufuna kugula zinthu zapakati pa data kapena kufunsa mafunso okhudzana ndi zina, chonde tumizani pempho lanu ku https://www.ec3dao.com/, ndipo tikuyankhani uthenga wanu mwachangu. Zikomo chifukwa cha thandizo lanu ndi chikhulupiriro chanu!
