Chapter 4 Testing and Diagnostics FOM-E1/T1 Installation and Operation Manual
4-4 Frequently Asked Questions
4.4 Frequently Asked Questions Q: Does FOM-E1/T1 operate opposite FOM-40?
A: No. The fiber optic interfaces of these modems are not compatible.
Q: Can I connect FOM-E1/T1 with a balanced interface to FOM-E1/T1 with an
unbalanced interface?
A: Yes
Q: What is the maximal distance between FOM-E1/T1 and end equipment (E1
link)?
A: The FOM-E1/T1 output conforms to the G.703 standard: the coding is bipolar
±3V (CDP) with the maximum attenuation of 6 dB. This gives us a range of
approximately 300 meters for a balanced 24 AWG (0.5 mm) line. The range for
a coax cable is about 150 meters.
