Amanothi:
1.Indawo yesiyingi ihlukaniswe ngaphakathi endaweni ye-chassis.
2.Okukhipha i-Laser kukhutshaziwe ku-TDIS >2.0V noma kuvuliwe, kunikwe amandla ku-TDIS <0.8V.
3.Kufanele idonswe nge-4.7k - 10kohms ebhodini lomsingathi ku-voltage ephakathi kuka-2.0V no-3.6V.MOD_DEF (0) idonsa umugqa uphansi ukuze kuboniswe ukuthi imojula ixhunyiwe.
4.Lokhu okokufaka ongakukhetha okusetshenziselwa ukulawula umkhawulokudonsa owamukelayo ukuze uhambisane namazinga edatha amaningi (okungenzeka kakhulu ukuthi i-Fiber Channel 1x kanye ne-2x Rates).Uma isetshenziswa, okokufaka kuzodonselwa phansi nge-> 30kΩ resistor. Izimo zokufaka yilezi:
- Phansi (0 – 0.8V): Umkhawulokudonsa owehlisiwe
- (>0.8, < 2.0V): Akuchazwanga
- Phezulu (2.0 – 3.465V): Umkhawulokudonsa ogcwele
- Vula: Umkhawulokudonsa Oncishisiwe
I-5.LOS iwukuphuma komqoqi ovulekile kufanele kudonswe nge-4.7k - 10kohms ebhodini lokusingatha ku-voltage ephakathi kuka-2.0V no-3.6V. I-Logic 0 ikhombisa ukusebenza okuvamile; i-logic 1 ibonisa ukulahlekelwa kwesignali.
