2. Mus rau hauv 100Ω qhov kev xaus sib txawv.

3. 20 – 80%. Ntsuas nrog Module Compliance Test Board thiab OMA test pattern. Kev siv plaub tus lej 1 thiab plaub tus lej 0 hauv PRBS 9 yog lwm txoj hauv kev uas siv tau.

4. LOS yog qhov qhib qhov tso zis ntawm tus neeg sau. Yuav tsum rub nrog 4.7kΩ - 10kΩ ntawm lub rooj tsavxwm. Kev ua haujlwm ib txwm yog logic 0; poob ntawm lub teeb liab yog logic 1.

Cov Yam Ntxwv Txog Kev Pom Kev (TOP(C) = 0 txog 70 ℃, TOP(I) = -40 txog 85 ℃, VCC = 3.13 txog 3.47 V)

Cov Lus Cim:

1. Cov lej nruab nrab ntawm lub zog tsuas yog cov ntaub ntawv qhia xwb, raws li IEEE 802.3ae.

2. Ntsuas ntawm BER tsawg dua 1E-12, rov qab sib rau. Tus qauv ntsuas yog PRBS 2^31-1nrog qhov phem tshaj plaws ER = 4.5 @ 10.3125Gb / s.

Cov Lus Txhais thiab Kev Ua Haujlwm ntawm Pin

Cov Lus Cim:

1. Lub hauv av ntawm lub voj voog module raug cais tawm ntawm lub hauv av ntawm lub chassis module hauv lub module.

2. Yuav tsum tau rub nrog 4.7k - 10k ohms ntawm tus tswv tsev board rau ib tug voltage ntawm 3.15Vand 3.6V.

3. Tx_Disable yog ib qho input contact nrog 4.7 kΩ txog 10 kΩ pullup rau VccT hauv lub module.
