OP-QSFP28-01 e etselitsoe ho sebelisoa lihokelong tse 100 tsa Gigabit motsotsoana holim'a fiber ea mefuta e mengata.
Li lumellana le QSFP28 MSA le IEEE 802.3bm. Karolo ea optical transmitter ea transceiver e kenyelletsa sehlopha sa 4-channel VCSEL (Vertical Cavity Surface Emitting Laser), mochine oa ho kenya mochine oa 4-channel le mokhanni oa laser, li-monitor tsa ho hlahloba, li-blocks tsa taolo le tse fapaneng. Bakeng sa taolo ea module, sebopeho sa taolo se kenyelletsa sebopeho sa Two Wire Serial sa oache le matšoao a data. Diagnostic monitors bakeng sa
VCSEL bias, mocheso oa module, matla a optical a fetisitsoeng, matla a optical a amohetseng le motlakase oa phepelo o kenngoa ts'ebetsong 'me liphello li fumaneha ka sebopeho sa TWS. Alamo le litemoso tsa temoso li thehiloe bakeng sa litšobotsi tse behiloeng leihlo. Lifolakha li behiloe 'me li sitisoe li hlahisoa ha ho

Litšitiso tsohle li ka koaheloa 'me lifolakha li hlophisoa bocha ka ho bala ngoliso e nepahetseng ea folakha. Sephetho sa optical se tla fokotsa tahlehelo ea lets'oao la ho kenya ntle le haeba squelch e koetsoe. Ho lemoha liphoso kapa ho tima kanale ka sebopeho sa TWS ho tla tima mocha. Boemo, alamo / tlhokomeliso le tlhaiso-leseling ea liphoso li fumaneha ka sebopeho sa TWS.
Karolo ea optical receiver ea transceiver e kenyelletsa 4-channel PIN photodiode array, 4-channel TIA array, 4 channel output buffer, li-monitor tsa ho hlahloba, le li-blocks tsa taolo le leeme. Li-monitor tsa tlhahlobo ea matla a optical li kenngoa ts'ebetsong 'me liphetho li fumaneha ka sebopeho sa TWS. Alamo le litemoso tsa temoso li thehiloe bakeng sa litšobotsi tse behiloeng leihlo. Lifolakha li behiloe 'me litšitiso li hlahisoa ha litšoaneleho li le ka ntle ho menyako.
