FAQ
1、Question: Does it works with any fiber cable such as om1, om2, om3, om4 multimode fiber cables?
Answer: Yes, OM1, OM2, OM3, OM4 LC to LC duplex multimode fiber cables can all work with this module.
2、Question: If i wanted to connect a brocade to a netgear using a sfp+ module, if i mixed the brocade and netgear transceivers, they should work right?
Answer: As long as both devices recognize the SFP+ modules installed, i.e. sending/receiving light, then connectivity will work between the two using Ethernet standards.
3、Question：What are CWDM, DWDM, SFP and GBIC used for? What kind of company buys them?
Answer：These are optical fiber transceivers designed to be used with passive optical multiplexers. If you have a number of these all transmitting on different wavelengths, you can use a passive multiplexer to combine each signal onto a single fiber pair, and then de-multiplex the signal at the far end. Unlike active systems, a passive multiplexer requires no power or management - it's literally a set of waveguides and prisms in a rack mount chassis - which greatly reduces the cost of doing WDM and eliminates a potential point of failure in the system.
