SFP modules inoita kuti data iende nekukurumidza
Nekukurumidza kukura kwehungwaru hwekugadzira uye data data data, kudiwa kwepamusoro-kumhanya, hukuru-hukuru hwekufambisa data huri kuwedzera zvakare, izvo zvinowedzera kufambisa kusimudzira nekushandiswa kweSFP modules.
TheSFP moduleinopisa-inochinjika diki pasuru module muSFP package. SFP modules inonyanya kuumbwa ne lasers. SFP classification inogona kukamurwa kuita chiyero chechiyero, wavelength kupatsanura, uye modhi yemhando.
Inogona kungonzwisiswa seyakakwidziridzwa vhezheni yeGBIC. SFP module's vhoriyamu yakaderedzwa nehafu kana ichienzaniswa neiyo GBIC module, ingangoita saizi yechigunwe. Zvinopfuura zvakapetwa kaviri nhamba yezvikepe zvinogona kugadzirwa pane imwechete panel. Mamwe mabasa eSFP module akanyanya kufanana neaya eGBIC.
- Rate classification
Maererano nekumhanya, kune155M/1.25G/10G/40G/100G. 155M uye 1.25G inonyanya kushandiswa mumusika. Iyo tekinoroji ye10G iri kukura zvishoma nezvishoma, uye kudiwa kuri kukura mune yakakwira maitiro.
- Wavelength classification
Zvinoenderana newavelength, kune 850nm/1310nm/1550nm/1490nm/1530nm/1610nm. Iyo wavelength ye850nm is SFP multi-mode, uye kureba kwekufambisa kuri pasi pe2KM. Iyo wavelength ye1310/1550nm ndeye-single-modhi, uye kureba kwekufambisa kunodarika 2KM. Zvichienderana nekutaura, izvi Mitengo yemawavelength matatu yakachipa kupfuura mamwe matatu.
Single-modhi faibha yakachipa, asi imwe-modhi midziyo inodhura zvakanyanya pane yakafanana multi-modhi michina. Zvishandiso zve-single-mode zvinowanzoshanda pane ese-single-mode uye akawanda-modhi faibha, nepo akawanda-modhi midziyo inogumira kune akawanda-modhi faibha.
JHA Tech, kambani yemakore gumi nemanomwe ine hunyanzvi hwayo hweR&D uye mafekitori, inokwanisa kupa maSFP mamodule ane madiki emapakeji saizi uye yakakwirira chiteshi. Sezvo mashandisirwo emagetsi emidziyo yakadai semaseva uye Ethernet Switch ichiramba ichikwira, mashandisirwo emagetsi zvinodiwa zveSFP modules ari kuramba achiwedzera kuomarara. Kuderera kwesimba rekushandisa SFP modules kwete chete kuderedza simba rose rekushandisa kwemidziyo, asiwo inovandudza kugadzikana uye kuvimbika kwemidziyo.
Unoda kuziva here nezvekubatsira kweEthernet Switchnenhamba huru dzechiteshi? Nyaya inotevera ichakusuma. Kana iwe uchida kuziva pachine nguva, ndapota siya email kero yako uye isu tichava nenyanzvi yekukubata iwe kuti uwane mhinduro dzemunhu-pamwe.
