I-Cisco Compatible 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC MMF Optical Transceiver Module, Ukuqhekeka kuya ku-4 x 25G-SR ene-DDM
Incazelo
+ I-Cisco QSFP-100G-SR4-S Compatible QSFP28 Optical Transceiver Module yenzelwe ukusetshenziswa ku-100GBASE Ethernet throughput efinyelela ku-100m phezu kwe-OM4 multimode fiber (MMF) kusetshenziswa ubude be-wavelength obungu-850nm ngesixhumi se-MTP/MPO-12. Le transceiver ihambisana ne-IEEE 802.3bm 100GBASE-SR4 kanye ne-CAUI-4 standard. Imisebenzi yokuxilonga yedijithali iyatholakala futhi nge-interface ye-I2C, njengoba kuchaziwe yi-QSFP28 MSA, ukuvumela ukufinyelela kumapharamitha okusebenza wesikhathi sangempela. Ngalezi zici, le transceiver elula ukuyifaka, eshisayo eshintshwayo ifanelekile ukusetshenziswa ezinhlelweni zokusebenza ezahlukahlukene, njengezikhungo zedatha, amanethiwekhi ekhompyutha asebenza kahle kakhulu, izinhlelo zokusebenza ze-core core kanye nezendlalelo zokusabalalisa.

Incazelo Ejwayelekile
Ama-OP-QSFP28-01 aklanyelwe ukusetshenziswa kuma-Gigabit angu-100 ngomzuzwana phezu kwe-fiber yemodi eminingi.
Ziyahambisana ne-QSFP28 MSA kanye ne-IEEE 802.3bm. Ingxenye ye-optical transmitter ye-transceiver ifaka i-VCSEL (Vertical Cavity Surface Emitting Laser) eneziteshi ezine, i-buffer yokufaka eneziteshi ezine kanye nomshayeli we-laser, ama-diagnostic monitors, ama-control kanye nama-bias blocks. Ukuze kulawulwe imodyuli, i-control interface ifaka i-Two Wire Serial interface yewashi kanye nezimpawu zedatha. Ama-diagnostic monitors e-
Ukubandlulula kwe-VCSEL, izinga lokushisa lemojuli, amandla okukhanya adluliselwe, amandla okukhanya atholiwe kanye ne-voltage yokunikezela kuyasetshenziswa futhi imiphumela iyatholakala nge-interface ye-TWS. Imingcele ye-alamu kanye nesexwayiso isungulwa yezimfanelo eziqashwe. Amafulegi ayasethwa futhi ukuphazamiseka kukhiqizwa lapho
izimfanelo zingaphandle kwemingcele. Amafulegi ayasethwa futhi kukhiqizwe ukuphazamiseka kokulahlekelwa isignali yokufaka
(LOS) kanye nezimo zamaphutha okudlulisela. Wonke amafulegi ayavalwa futhi azohlala emisiwe noma ngabe isimo esiqala i-latch siyaphela futhi ukusebenza kuyaqhubeka. Zonke iziphazamiso zingavalwa futhi amafulegi asethwe kabusha ngokufunda irejista efanele yefulegi. Ukuphuma kwe-optical kuzoncibilikisa ukulahleka kwesiginali yokufaka ngaphandle kokuthi i-squelch ikhutshaziwe. Ukutholwa kwamaphutha noma ukuvalwa kwesiteshi ngokusebenzisa isikhombimsebenzisi se-TWS kuzokhubaza isiteshi. Isimo, i-alamu/isixwayiso kanye nolwazi lwamaphutha kuyatholakala ngesikhombimsebenzisi se-TWS.
Ingxenye yokwamukela okubonakalayo ye-transceiver ifaka i-photodiode array ye-PIN yeziteshi ezine, i-TIA array yeziteshi ezine, i-buffer yokukhipha iziteshi ezine, ama-diagnostic monitors, kanye nama-control kanye nama-bias blocks. Ama-diagnostic monitors anamandla okufaka okubonakalayo ayasetshenziswa futhi imiphumela iyatholakala nge-interface ye-TWS. Imingcele ye-alamu kanye nesexwayiso isungulwe yezimfanelo eziqashwe. Amafulegi ayasethwa futhi kuphazanyiswe lapho izimfanelo zingaphandle kwemingcele. Amafulegi ayasethwa futhi kuphazanyiswe ukulahleka kwesignali yokufaka okubonakalayo (LOS). Wonke amafulegi ayavalwa futhi azohlala esethiwe noma ngabe isimo esiqala ifulegi siphela futhi ukusebenza kuyaqhubeka. Zonke iziphazamiso zingavalwa futhi amafulegi aphinde asethwe kabusha lapho kufundwa irejista efanele yefulegi. Ukuphuma kukagesi kuzoncipha ukulahleka kwesignali yokufaka (ngaphandle kokuthi i-squelch ikhutshaziwe) kanye nokucishwa kwesiteshi nge-interface ye-TWS. Isimo kanye nolwazi lwe-alamu/isexwayiso luyatholakala nge-interface ye-TWS.
