Kodi optical fiber transceiver module SFP imagwira ntchito bwanji?

1. Kodi gawo la transceiver ndi chiyani?

Ma module a Transceiver, monga momwe dzinalo likusonyezera, ndi bidirectional, ndipo SFP ndi imodzi mwa izo.Mawu oti "transceiver" ndi kuphatikiza kwa "transmitter" ndi "receiver".Chifukwa chake, imatha kukhala ngati chotumizira komanso cholandila kuti ikhazikitse kulumikizana pakati pa zida zosiyanasiyana.Zogwirizana ndi gawoli ndizomwe zimatchedwa mapeto, momwe gawo la transceiver lingalowetsedwe.Ma module a SFP adzafotokozedwa mwatsatanetsatane m'mitu yotsatirayi.
1.1 Kodi SFP ndi chiyani?

SFP ndi yachidule ya Small Form-factor plugable.SFP ndi gawo lokhazikika la transceiver.Ma module a SFP amatha kulumikiza liwiro la Gbit/s pamanetiweki ndikuthandizira ma multimode ndi ma singlemode fibers.Mtundu wodziwika bwino wa mawonekedwe ndi LC.Zowoneka bwino, mitundu yolumikizana ndi ulusi imatha kudziwikanso ndi mtundu wa tabu ya SFP yokoka, monga momwe tawonetsera pa Chithunzi B. Mphete yokoka buluu nthawi zambiri imatanthawuza chingwe chamtundu umodzi, ndipo mphete yokoka imatanthawuza chingwe chamitundu yambiri.Pali mitundu itatu ya ma module a SFP osankhidwa malinga ndi liwiro la kufalikira: SFP, SFP +, SFP28.
1.2 Kodi pali kusiyana kotani pakati pa QSFP?

QSFP imayimira "Quad Form-Factor Pluggable".QSFP imatha kukhala ndi njira zinayi zosiyana.Monga SFP, ulusi wa single-mode ndi multimode ukhoza kulumikizidwa.Njira iliyonse imatha kufalitsa mitengo ya data mpaka 1.25 Gbit/s.Choncho, chiwerengero chonse cha deta chikhoza kufika ku 4.3 Gbit / s.Mukamagwiritsa ntchito ma module a QSFP +, njira zinayi zimathanso kumangidwa.Chifukwa chake, kuchuluka kwa data kumatha kufika 40 Gbit / s.
