Laser yathu yopepuka yopompedwa ndi Erbium-Doped Fiber imagwiritsidwa ntchito ndi gawo loyambirira lomangirira kuchokera ku USA.
Tili ndi mphamvu yodalirika yotulutsa magetsi okhazikika komanso kutentha kwa firiji yamagetsi ya laser kuti tiwongolere dera, tikutsimikizira kuti makinawo amagwira ntchito bwino kwambiri komanso kuti laser igwire ntchito nthawi yayitali.
Pulogalamu ya microprocessor ili ndi chowunikira momwe zinthu zilili ndi laser, chenjezo la zolakwika pakuwonetsa kwa digito, kasamalidwe ka netiweki ndi ntchito zosiyanasiyana. Pulogalamu ya laser ikangokhazikitsa malire a chilolezo, imatseka mphamvu ya laser yokha. Kuwala kofiira, alamu yofulumira komanso piritsi losinthira digito limasonyeza chomwe chimayambitsa vuto.
Pulogalamu ya microprocessor imapereka mawonekedwe a RS-232 ndi 485 omwe amagwiritsidwa ntchito poyang'anira maukonde ndi kuyang'anira kutali.
Timagwiritsa ntchito mphamvu yosinthira ya 1RU 19” yokhazikika ya chimango cha injini, mphamvu yogwiritsira ntchito ya 90-265V.
Makhalidwe Ogwira Ntchito Kusankhidwa kwa mtundu wotchuka wapadziko lonse wa laser ya pampu yopanda phokoso lotsika, kupotoza kotsika, gulu lonse, mphamvu yayikulu yowunikira Imagwiritsa ntchito ulusi wa nyambo zogwira ntchito kwambiri zomwe zimatumizidwa kunja, komanso mphamvu zambiri zosinthira. Ma laser amphamvu ndi opompedwa amitundu yonse ya ntchito, kuonetsetsa kuti mphamvu yotulutsa kuwala imakhala yokhazikika, ndikuwonjezera bwino nthawi yogwira ntchito ya laser ya pampu. Chowonetsera cha LCD cha kutsogolo chokhala ndi mzere wabuluu cha 160*32 dot-matrix, chowonetsa momwe zida zilili. Ma rack 19 “1U apamwamba kwambiri, okhala ndi zida zogwirizana ndi ma interfaces a Ethernet a IEEE802.310Base-T ndi RS-232, amatha kuthandizira kukwaniritsidwa kwa netiweki. Chithandizo chathunthu cha "GB/T 20030-2005 kasamalidwe ka dongosolo la zida za HFC network specifications"
