SFP Module ili ndi chipangizo chowoneka bwino, mawonekedwe ozungulira komanso mawonekedwe owoneka bwino.Chipangizo chowunikira chimakhala ndi magawo otumizira ndi kulandira.
Gawo lopatsirana ndi: kuyika kwa nambala inayake ya ma siginecha amagetsi, kudzera mu makina oyendetsa chip mkati, kuyendetsa semiconductor laser (LD) ya diode yotulutsa kuwala (LED) kutumiza chizindikiro chofananira chosinthira mawonekedwe, kuwala mkati operekedwa ndi makina owongolera magetsi odziwikiratu.Mphamvu yamagetsi yotulutsa kuwala imakhalabe yokhazikika.
Gawo lolandirira ndi: gawo la optical sign input module la code rate limasinthidwa kukhala chizindikiro chamagetsi kudzera mu diode yowunikira.Pambuyo pa preamplifer, chizindikiro chotulutsa cha mulingo wofananira ndi mulingo wa PECL.Pamene mphamvu ya kuwala yolowetsayo ili yochepa kuposa mtengo wina, chizindikiro cha alamu chimapangidwa.
Ma parameters ndi tanthauzo la ma module optical
Ma module a Optical anali ndi zofunikira zaukadaulo zaukadaulo.Komabe, pa GBIC ndi SFP hot-plug SFP Modules, muyenera kulabadira magawo atatu otsatirawa.
Kutengera nanometer(nm), pali mitundu itatu yayikulu pakadali pano.
850nm (MM, multi-mode, otsika mtengo koma lalifupi kufala mtunda, zambiri 500M okha).
1310nm (SM, Single Mode, kutaya pang'ono kufala, kubalalitsidwa kwakukulu, komwe kumagwiritsidwa ntchito kufalitsa mtunda wautali pa 40KM, palibe kulandilana komwe kungatumize mwachindunji 120KM).
1550nm (SM, Single Mode, kutaya pang'ono, kubalalitsidwa kwakukulu, komwe kumagwiritsidwa ntchito kufalitsa mtunda wautali pa 40KM, palibe kubwereza komwe kumatumiza 120KM).
Mtengo wotumizira
Nambala ya bits (BPS) ya data yotumizidwa pamphindikati.
Panopa.Pali ma SFP Modules anayi omwe amagwiritsidwa ntchito kwambiri.155Mbps, 1.25Gbps, 2.5Gbps, 10Gbps ndi zina zotero.Kusamutsa mlingo nthawi zambiri m'mbuyo n'zogwirizana.Choncho, 155M SFP Module imatchedwanso FE (100Mbit/s) SFP Module, ndipo 1.25G SFP Module imatchedwanso GE (Gigabit) Optical module.
Iyi ndi SFP yomwe imagwiritsidwa ntchito kwambiri pazida zotumizira zamagetsi.Kuphatikiza apo, mitengo yake yotumizira mu fiber optic storage systems ( SAN) ndi 2Gbps, 4Gbps, ndi 8Gbps.
Mtunda wotumizira
Chizindikiro cha Optical sichiyenera kutumizidwa kutali komwe angatumizidwe mwachindunji.Mu kilomita (yomwe imatchedwanso kilomita, KM).Mafotokozedwe a SFP Modules ndi awa: Multi-Mode 550M, Single-Mode 15KM, 40KM, 80KM, ndi 120KM, ndi zina zotero.
