PPC-100/STM-1 is wireless point-to-point link that provide mm-wave radio performance for wireless 155 mbit STM-1 connectivity. These links are available at the following mm-wave bands: 40.5 - 43.5 GHz, 57.0 - 65.0 GHz, 71-76 GHz and 81-86 GHz, and 92-95 GHz.
| Applications of
Point-to-point PPC-100/STM-1 Links The primary applications for PPC-100/STM-1 with STM-1 interface are wireless SDH / ATM rings. ELVA-1’s PPC-100/STM-1 systems provide an STM-1 optical interface, allowing these links to be a part of the optical SDH ring. Especially in urban areas where it is difficult to bring optical fiber due to cable trenching problems, PPC-100/STM-1 links make a quick and cost-effective installation possible. Other general purpose applications are the following:
|
PPC-100/STM-1 links are featured with
remote management and parameter monitoring capabilities. To communicate
with the link for SNMP and parameter control, there is a special twisted
pair cable patch which has to be connected to any RJ-45 socket within LAN,
deployed in the building. This allows remote SNMP management and remote
parameter monitoring of
PPC-100/STM-1 links from a central location.
The 155 Mbps point-to-point millimeter wave radio systems are available with a choice of three different sizes of compact parabolic Cassegrain antenna - 30 cm, 45 cm, and 60 cm. Depending of the link frequency, these antennas deliver operating distances from about 1.5 mile to 9.5 miles (2.5 km to 15 km) for fair weather condition.
For easy adjusting of radios to a true line of sight, PPC-100/STM-1 link is shipped with aux electronic adjusting unit. This unit has own 1-line display to see changes in primary parameters of the link gain during adjustment process.
Special PPC software application is used to detect, monitor, and configure ElvaLink terminals connected within the same network. The PPC Main window displays status readings and parameter values for the active PPC-100/STM-1 terminal.

[*] Max operating distance calculated
for weather conditions of 5mm/hour rain.
To understand what is the 5mm/hour rain,
see the list of meteorological data below to compare (for
continental USA and Europe):
- Drizzle 2mm/hour
- Light rain 5mm/hour
- Steady rain 12mm/hour
- Summer cumulus rain 15mm/hour
- Heavy rain 20mm/hour
[**] Output power level for 60 GHz band
depends on antenna size
