Amanothi:
1. Uma iphezulu, lokhu kukhishwa kubonisa iphutha le-laser lohlobo oluthile. Okuphansi kubonisa ukusebenza okuvamile. Futhi kufanele kudonswe phezulu nge-resistor engu-4.7 - 10KΩ ebhodini lokusingatha.
2. I-TX disable iyi-input esetshenziselwa ukuvala i-transmitter optical output. Idonswa ngaphakathi kwe-module nge-resistor engu-4.7 - 10KΩ. Izimo zayo yilezi:
Okuphansi (0 – 0.8V): I-Transmitter ivuliwe (>0.8, < 2.0V): Akucacisiwe
Okuphezulu (2.0V~Vcc+0.3V): I-Transmitter Ikhutshaziwe Ivuliwe: I-Transmitter Ikhutshaziwe
3. I-Mod-Def 0,1,2. Lezi yizikhonkwane zencazelo yemojuli. Kufanele zidonswe phezulu nge-resistor engu-4.7K – 10KΩ ebhodini lokusingatha. I-voltage yokudonsa kufanele ibe phakathi kuka-2.0V ~ Vcc + 0.3V.
I-Mod-Def 0 isekelwe yi-module ukukhombisa ukuthi i-module ikhona
I-Mod-Def 1 iwumugqa wewashi wesixhumi esibonakalayo se-serial esinezintambo ezimbili se-serial ID
