Ayyukan na'urar gani da ido shine canjin hoto. Optical transceivers are widely used in various industries. Aerech Networks will use this article to introduce you to the application scenarios of optical transceivers.

Before introducing the application scenarios of optical transceivers, let me introduce you to the market segments of optical transceivers.

1. Ethernet: Ana amfani da shi a cikin cibiyoyin sadarwa na yanki, haɗa na'urorin hardware na cibiyar sadarwa ta hanyar aikawa da karɓar siginar bayanai.
2. Fiber Chanel: Ana amfani da shi a cikin hanyoyin haɗin yanar gizo na ajiya na Fiber Channel a cikin cibiyoyin bayanai.
3. Haɗin kai na gani: Cibiyar sadarwa ta IP ta amfani da fasahar watsa WDM, galibi ana amfani dashi don watsa fakitin IP. Kasuwar sadarwa
4. CWDM/DWDM: Ana amfani da shi sosai a cikin haɗin kai na masu sauyawa a cikin cibiyar bayanai da kuma gaba da baya na cibiyoyin sadarwar 5G..
5. Wireless Fronthaul: An fi amfani dashi a cikin hanyar sadarwa tsakanin rukunin BBU na baseband da naúrar rediyo mai nisa RRU a cikin tashar wayar hannu.
6. Wireless Backhaul: An fi amfani dashi a cikin hanyar sadarwa tsakanin rukunin BBU na baseband da S-G W/MME a cikin tashar wayar hannu..
7. FTT: Fiber zuwa X, x iya gida, gini , da dai sauransu. Fasahar da ke fahimtar FTTx sun haɗa da PON, EPON, GPON, da dai sauransu., waɗanda ake amfani da su don haɗa masu amfani da tarho da masu amfani da ƙarshen.

The application of optical transceivers is mainlytelecommunications anddata centers.

Cibiyoyin Bayanai

Cibiyar bayanai ita ce wurin sarrafawa (kantin sayar da, lissafta, musanya) data. Haɗin kai tsakanin cibiyoyin bayanai shine ainihin-lokacin musayar bayanai tsakanin cibiyoyin bayanai, kuma sadarwar fiber na gani na iya fahimtar aiki tare tsakanin cibiyoyin bayanai. Kayan aiki na sauyawa yana buƙatar samun mafi girma gudu, ƙananan amfani da wutar lantarki, kuma mafi miniaturization, optical transceivers play a major role. Saboda cibiyoyin sadarwar bayanai galibi sun dogara ne akan watsa siginar gani, yayin da ƙididdiga da bincike sun dogara ne akan siginar lantarki.

Optical transceivers can be divided into three categories according to the type of data center communication connection.

1. Cibiyar bayanai da masu amfani: Ƙarshen masu amfani suna samun damar gajimare don bincika shafukan yanar gizo, aika da karɓar imel, watsa bidiyo, da dai sauransu.
2. Haɗin cibiyar bayanai: akasari ana amfani dashi don kwafin bayanai, software da haɓaka tsarin;
3. Cibiyar bayanai na ciki: galibi ana amfani da su don adana bayanai da tsarawa.

Bisa ga kididdigar Cisco, cibiyar sadarwa ta cibiyar sadarwa ta fiye da 70% na sadarwar cibiyar sadarwa. The construction and upgrade of data centers have increased the demand for high-speed optical transceivers, and also promoted the development of optical transceivers in the following three aspects:

1. Girma a cikin buƙatar ƙimar watsawa
2. Girman buƙatun yawa
3. Girma a cikin buƙatar nisa watsawa

Kudin hanyar haɗin fiber na gani ya dogara da ƙirar gani da fiber na gani. Nisa daban-daban suna da mafita na hanyar sadarwa daban-daban. Don matsakaita da haɗin kai mai nisa da ake buƙata don sadarwar cibiyar bayanai, MSA ta ƙirƙiri mafita na juyin juya hali guda biyu, PSM4 (Daidaitaccen Yanayin Single 4 hanyoyi) da CWDM4 (Matsakaicin Wavelength Division Multiplexer 4 hanyoyi). Tun da amfani da fiber na PSM4 shine sau huɗu na CWDM4, lokacin da nisa na mahada ya yi tsawo, farashin CWDM4 bayani yana da ƙananan ƙananan, kuma shine mafi kyawun zabi.

Tashar Sadarwa ta Waya

Tsakanin su, cibiyar sadarwar SAN ta ƙunshi sabobin ne, Fiber Channel yana canzawa, na'urorin ajiya, da kuma masu jigilar kayayyaki (optical transceivers, Optical fiber jumpers); cibiyar sadarwar ajiyar NAS ta ƙunshi babban ma'ajiyar NAS, masu sauyawa, m kayan aiki (kwamfutoci), masu dakon watsawa (optical transceivers, fiber na gani) tsalle). Please note that the SAN network uses Fibre Channel optical transceivers and needs to support the FC(Fiber Channel) yarjejeniya. The optical transceivers used in the NAS storage network are only required to comply with the Ethernet protocol.

5G Bearer Network

Zuwan 5G yana kawo damar kasuwanci mara iyaka zuwa sadarwar gani. Optical transceivers based on 5G base stations have become a research hotspot in the past two years. Cibiyar sadarwar 5G ta ƙunshi sassa uku, hanyar sadarwar shiga, cibiyar sadarwa mai ɗaukar nauyi, da core network.
