Muchinyorwa chino ini ndichataura nezve izvo zvinokonzeresa kurasikirwa mukufambiswa kwefiber optics. Ngatidzidzei…
Chikonzero nei optical fiber ichitsiva iyo yepakati uye kure-kure kufambisa kwetambo dzetiweki imhaka yekuti optical fiber transmission ine kurasikirwa kwakaderera, uye kurasikirwa kwayo kunokamurwa zvakanyanya kuita zvinotevera:
Kurasikirwa ndiko kurasikirwa kwesimba rechiedza kunokonzerwa nekunyura, kupararira uye kubuda kwepakati (mhepo) kana mwenje uchifambiswa mu optical fiber (iyo optical fiber haigone kutsaura zvachose mwenje, izvo zvinozotungamira mukudonha kwechiedza). Kurasikirwa kwechikamu ichi chesimba kunowedzera nekufamba kure. Kuwedzera kunobviswa pane imwe chiyero.
Semuenzaniso: 1310nm optical module inoverengera kurasikirwa kwekutapurirana pa 0.35dBm/km,
Iyo 1550nm optical module inoverengera iyo link kutapurirana kurasikirwa pa 0.20dBm/km.Uye kurasikirwa uku kuchakanganiswawo nemitengo yakasiyana, uye kurasikirwa kwekutapurirana kwekubatanidza kunoenderana nechiyero.
Kupararira kunonyanya kukonzerwa nenyaya yekuti masaisai emagetsi emagetsi akasiyana-siyana anofamba ari pakati nepakati achimhanya kwakasiyana, zvichikonzera kuti zvikamu zvakasiyana-siyana zvewavelength zvechiratidzo chemaziso zvinosvika pamagumo ekugamuchira panguva dzakasiyana nekuda kwekuunganidzwa kwemafashama ekufambisa, zvichikonzera kupuruzira. kuwedzera uye kusakwanisa kusiyanisa chiratidzo. value. Kuverengera kukosha kwekuparadzira kwakaoma uye kazhinji kunongo reva chete.
Kurasikirwa kwekupinza, chero bedzi iyo interface inopera mu optical fiber yakavharwa, isina kuvharwa zvachose, zvichiita kuti chiedza chivhare uye zvimwe zviitiko, zvichiita kuti kurasikirwa uku kwekuisa. Kazhinji, kurasikirwa kwekuisa kuri pakati pe0.15-0.35dbm.
Zviri pamusoro apa itsananguro yekurasikirwa neruzivo rwe optical fiber transmission yakaunzwa neShenzhen HDV photoelectric Technology Co., Ltd. Zvigadzirwa zvemodule zvinogadzirwa nekavha yekambani. optical fiber modules, Ethernet modules, Optical fiber transceiver modules, Optical fiber access modules, SSFP Optical modules,uyeSFP optical fibers, etc. Zvigadzirwa zvemodule zviri pamusoro zvinogona kupa rutsigiro kune akasiyana network. Nyanzvi uye yakasimba R&D timu inogona kubatsira vatengi nenyaya dzehunyanzvi, uye timu inofunga uye ine hunyanzvi bhizinesi inogona kubatsira vatengi kuwana masevhisi emhando yepamusoro panguva yepamberi yekubvunzana uye mushure mekugadzira basa. Tinokugamuchirai taura nesu kune chero rudzi rwekubvunza.
