Amanothi:
1. Inhlabathi yesekethe ihlukaniswe ngaphakathi nomhlabathi we-chassis.
2. Ukukhishwa kwe-laser kukhutshaziwe ku-TDIS >2.0V noma kuvuliwe, kuvuliwe ku-TDIS <0.8V.
3. Kufanele idonswe phezulu nge-4.7k - 10kohms ebhodini lokusingatha ku-voltage ephakathi kuka-2.0V no-3.6V. I-MOD_DEF (0) idonsa umugqa ophansi ukukhombisa ukuthi imojuli ixhunyiwe.
4.Lokhu ukufaka okungakhethwa okusetshenziselwa ukulawula i-bandwidth yokwamukela ukuze kuhambisane namazinga edatha amaningi (cishe amazinga e-Fiber Channel 1x kanye nama-2x). Uma kusetshenziswe, ukufaka kuzodonswa ngaphakathi nge-resistor engu-> 30kΩ. Izimo zokufaka yilezi:
- Okuphansi (0 – 0.8V): Ububanzi Bomkhawulo Obuncishisiwe
- (>0.8, < 2.0V): Akucacisiwe
- Okuphezulu (2.0 – 3.465V): I-bandwidth ephelele
- Vula: Ububanzi Bomkhawulo Obuncishisiwe
5. I-LOS ivulekile, umkhiqizo wokuqoqa kufanele udonswe phezulu nge-4.7k - 10kohms ebhodini lokusingatha ku-voltage ephakathi kuka-2.0V no-3.6V. I-Logic 0 ikhombisa ukusebenza okuvamile; i-logic 1 ikhombisa ukulahlekelwa kwesignali.
