Tuhipoka:
1.Ko te papa porowhita kua wehea o roto mai i te papa tahuhu.
2.Ko te putanga taiaho kua monokia i runga i te TDIS>2.0V, i te tuwhera ranei, kua taea ki te TDIS <0.8V.
3.Me toia ake me te 4.7k - 10kohms i runga i te papa manaaki ki te ngaohiko i waenga i te 2.0V me te 3.6V.MOD_DEF (0) ka kumea te raina iti hei tohu kua whakauruhia te kōwae.
4.He whakaurunga whiriwhiringa tenei hei whakahaere i te peera o te kaiwhiwhi mo te hototahi ki nga reiti raraunga maha (te nuinga pea ko te Fiber Channel 1x me te Reiti 2x).Ki te whakatinanahia, ka toia te whakaurunga ki raro me te > 30kΩ parenga. Ko nga ahuatanga whakauru ko:
- Iti (0 – 0.8V): Aratuku Whakaiti
- (>0.8, <2.0V): Kaore i tautuhia
- Teitei (2.0 – 3.465V): Aratuku Katoa
- Tuwhera: Aratuku Whakaiti
5.LOS he tuwhera kaikohi putanga me toia ake ki te 4.7k - 10kohms i runga i te papa manaaki ki te ngaohiko i waenganui i 2.0V me 3.6V. Ko te arorau 0 te tohu mahi noa; arorau 1 tohu mate o te tohu.
