Frequently Asked Questions About SunFDDI 139
A
•
Does SunFDDI/P Dual incorporate an optical bypass?
No. You must order an optical bypass switch from a third-party vendor.
•
Why does my optical bypass switch not work when I plug it in?
Optical bypass switches require a power cycle to be initialized. Plug in the
optical bypass switch, switch off the FDDI station, and then reboot to
initialize the station. See “Optical Bypass Switches” on page 62 for a more
detailed description.
•
How can I increase the distance between two SunFDDI/P stations?
SunFDDI/P supports multimode fiber connections only. This limits the
maximum distance between stations to two kilometers (1.24 miles). To
increase the distance between stations, either:
• Use converters from multi- to single-mode fiber, and a single-mode
connection between converters.
• Add more nodes between the stations to act as repeaters.
