FibeAir 4800 Installation and Operation Guide 5-19
Q: Does FA4800 withhold any MAC Addresses?
A: The FA4800 is a layer 2 Bridge (VLAN transparent). The built-in switch contains
a MAC Address table up to 2047.
Q: Can I use any category 5e cable in order to connect the IDU and ODU?
A: The cable should be suitable for outdoor use, and shielded Category 5e.
Q: What are the BER values expected in the FA4800 link?
A: 10-11 (according to BER sensitivity threshold)
Q: Does FA4800 use DSSS technique?
A: No, FA4800 uses the advanced OFDM technique.
Q: What are the main advantages of the FA4800 solution (e.g., wireline,
wireless, etc.) over other possible alternatives?
A:
• Easy and intuitive installation using audio indication.
• Easy configuration using the management software of overall link site-to-site,
there is no need to travel between the two sites in order to change the
configuration.

• Very light ODU (1.5 kg).
• No RF loses between IDU and ODU.
• Robust Air Interface Layer 2 ARQ insures “error-free” Ethernet service even in
harsh conditions. Retransmit mechanism for TDM esures low BER.
• Integrated up to 4 E1/T1 and Ethernet radio over one single product.
• Supports a variety of applications Voice and Data over single radio – no need
for external mediation device.
• Smooth migration to VoIP applications.
• Carrier class compliant with ITU standards for E1 and T1.
• Low and constant TDM latency (8 msec).
