Astaamaha: QSFP MSA u hoggaansan ◊ Awood gudbinta in ka badan 100m OM3 Multimode Fiber (MMF) iyo 150m ee OM4 MMF ◊ Hal +3.3V quwadda shaqaynaysa fiilada LC-duplex fiber caadiga ah ogolaan dib u isticmaalka kaabayaasha fiilooyinka ee jira Codsiyada: ◊ 40 Gigabit Ethernet isku xidha ◊ Datacom/Telecom switch & router links Transceiver loogu talagalay 40 Gigabit Ethernet Applications. Transceiver Tani waa qaab hawleedka sare ee isgaarsiinta xogta laba-gaaban iyo codsiyada isku xira. Waxay isku xidhaa afar haad xogta korantada ee jiho kasta si ay ugu gudbiso hal xadhig fiber optic LC duplex ah. Laad kasta oo koronto ah waxay ku shaqeysaa 10.3125 Gbps waxayna u hoggaansantaa 40GE XLPPI interface. Transceiver-gu gudaha wuxuu isku dhuftaa XLPPI 4 × 10G interface laba kanaal oo koronto ah oo 20Gb/s ah, gudbinta iyo helitaanka mid kasta si muuqaal ah oo ka sarreeya hal fiber LC fudud iyadoo la adeegsanayo indho-indheynta laba-jiho ah. Tani waxay keenaysaa isku-darka isku-darka xawaaraha 40Gbps ee xargaha laba-laaban ee LC. Tani waxay u oggolaanaysaa dib-u-isticmaalka kaabayaasha fiilooyinka laba-laabka ah ee LC-ga ee rakibay ee codsiga 40GbE. Masaafada isku xirka ilaa 100 m iyadoo la adeegsanayo OM3 iyo 150m iyadoo la adeegsanayo OM4 fiber optical waa la taageeray. Qaybahan waxa loo qaabeeyey inay ku shaqeeyaan hababka fibre-gaabyada kala duwan iyadoo la isticmaalayo mowjadda dhererka magaca ah ee 850nm iyo 900nm dhinaca kale. Isku xirka korantada wuxuu isticmaalaa xiriiriyaha cidhifka ah ee 38 QSFP+ Interface-ka indhaha waxa uu isticmaalaa isku xidhaha LC duplex ee caadiga ah.
