I-Cisco Compatible 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC MMF Optical Transceiver Module, Ukuqhekeka ukuya kwi-4 x 25G-SR ene-DDM
Inkcazo
+ I-Cisco QSFP-100G-SR4-S Compatible QSFP28 Optical Transceiver Module yenzelwe ukusetyenziswa kwi-100GBASE Ethernet throughput ukuya kuthi ga kwi-100m phezu kwe-OM4 multimode fiber (MMF) isebenzisa ubude be-850nm ngesixhumi se-MTP/MPO-12. Le transceiver iyahambelana ne-IEEE 802.3bm 100GBASE-SR4 kunye ne-CAUI-4 standard. Imisebenzi yokuxilongwa kwedijithali ikwafumaneka nge-interface ye-I2C, njengoko kuchaziwe yi-QSFP28 MSA, ukuvumela ukufikelela kwiiparameter zokusebenza ngexesha langempela. Ngezi mpawu, le transceiver elula ukuyifaka, eshushu etshintshanayo ifanelekile ukusetyenziswa kwizicelo ezahlukeneyo, ezinje ngamaziko edatha, iinethiwekhi zekhompyutha ezisebenzayo, i-enterprise core kunye nezicelo ze-distribution layer.

Inkcazo Jikelele
Ii-OP-QSFP28-01 zenzelwe ukusetyenziswa kwiikhonkco ze-100 Gigabit ngomzuzwana ngaphezulu kwefayibha ye-multi mode.
Ziyahambelana ne-QSFP28 MSA kunye ne-IEEE 802.3bm. Inxalenye ye-optical transmitter ye-transceiver ibandakanya uluhlu lwe-VCSEL (Vertical Cavity Surface Emitting Laser) oluneziteshi ezi-4, i-buffer yokufaka ye-4-channel kunye ne-laser driver, ii-diagnostic monitors, ii-control kunye nee-bias blocks. Kulawulo lwemodyuli, i-control interface ibandakanya i-Two Wire Serial interface ye-clock kunye ne-data signals. Ii-diagnostic monitors ze-
I-VCSEL bias, ubushushu bemodyuli, amandla okukhanya adluliselweyo, amandla okukhanya afunyenweyo kunye ne-voltage yonikezelo iyaphunyezwa kwaye iziphumo ziyafumaneka nge-interface ye-TWS. Imida ye-alamu kunye nesilumkiso imiselwe kwiimpawu ezijongiweyo. Iiflegi ziyasetwa kwaye ukuphazamiseka kwenziwa xa
iimpawu zingaphandle kwemida. Iiflegi nazo ziyasetwa kwaye iziphazamiso zenziwa ngenxa yokulahleka kwesiginali yokufaka
(LOS) kunye neemeko zempazamo yokudlulisela. Zonke iiflegi zibotshelelwe kwaye ziya kuhlala zimiselwe nokuba imeko eqala i-latch iyacima kwaye ukusebenza kuyaqhubeka. Zonke iziphazamiso zinokufihlwa kwaye iiflegi zisetwa kwakhona ngokufunda irejista yeflegi efanelekileyo. Isiphumo se-optical siya kucima ukulahleka kwesignali yokufaka ngaphandle kokuba i-squelch ikhutshaziwe. Ukufunyanwa kwempazamo okanye ukucima itshaneli nge-interface ye-TWS kuya kucima itshaneli. Isimo, i-alamu/isilumkiso kunye nolwazi lwempazamo ziyafumaneka nge-interface ye-TWS.
Inxalenye ye-optical receiver ye-transceiver ibandakanya uluhlu lwe-photodiode lwe-PIN olune-channel 4, uluhlu lwe-TIA olune-channel 4, i-output buffer ye-diagnostic monitors, kunye neebhloko zolawulo kunye ne-bias. Iimonitha zokuxilonga zamandla okufaka i-optical ziyasetyenziswa kwaye iziphumo ziyafumaneka nge-interface ye-TWS. I-alamu kunye ne-warning thresholds zimiselwe kwiimpawu ezijongiweyo. Iiflegi zisetwa kwaye ziyaphazamiseka xa iimpawu zingaphandle kwemida. Iiflegi nazo zisetwa kwaye ziyaphazamiseka ngenxa yokulahleka kwesignali yokufaka i-optical (LOS). Zonke iiflegi zibotshelelwe kwaye ziya kuhlala zisetwe nokuba imeko eqala iflegi iyacima kwaye ukusebenza kuyaqhubeka. Zonke iziphazamiso zinokufihlwa kwaye iiflegi zisetwa kwakhona xa kufundwa irejista yeflegi efanelekileyo. Imveliso yombane iya kucinezela ukulahleka kwesignali yokufaka (ngaphandle kokuba i-squelch ikhutshaziwe) kunye nokucinywa kwetshaneli nge-interface ye-TWS. Ulwazi lwesimo kunye ne-alamu/isilumkiso luyafumaneka nge-interface ye-TWS.
