Selecting a Site
Be sure to observe the following requirements when choosing a site for your
media converter.
❑
Select a site that is dust-free and moisture-free.
❑
Be sure that the site will allow you to easily access the fiber optic and
twisted pair cables and the power cord.
❑
Use dedicated power circuits or power conditioners to supply reliable
power to the device.

2. For maximum performance of Gigabit Optical Datalinks when greater than 40 km (24.8 mi) and operating within the
1550 nm optical spectrum, it is mandatory that the Single-mode Fiber (SMF) be rated as non-dispersion-shifted,
dispersion shifted, or non-zero dispersion shifted.
