PPC-100FE/8E1
Wireless LAN Bridge
with Optical Multiplexers
(1 port 100Mbit Fast Ethernet + 8x ports E1)
|
100Mbps +
8E1 Point-to-point wireless mm-wave link with total throughput
155Mbit and fiber optics interface
PPC-100FE/8E1 is wireless point-to-point link
that provides mm-wave radio connectivity for 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. The main channel is full-duplex 100Mbit Fast Ethernet plus
8xE1 additional channels transmitting simultaneously. The total link
throughput is 155Mbit which is coming to uplink port of optical mux
"100Mbps + 8E1". The link kit shipment includes two optical multiplexers
"100Mbps + 8E1" among two mm-wave radios (one for each side of the link).

Applications
of Point-to-point PPC-100FE/8E1 Links
For
PPC-100FE/8E1 model the primary application is interconnection
between base station sites in cellular networks (GSM / GPRS / UMTS).
PPC-100FE/8E1 provides an ideal intranet-intranet and
intranet-public network connection solution as wells as any LAN /
WAN connection where there is a requirement to combine data and
voice services in one link.
Other
general purpose applications are the following:
-
Wireless full duplex connection link for remote LAN segments at
corporate and university campuses
-
FSO (atmospheric laser) and fiber optics channel back-up
- Multipurpose
Fixed Wireless communications for any field use
|
PPC-100FE/8E1 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.
These
"100Mbps + 8E1" 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.
Note.
The only weather condition that could affect mm-wave link performance is
rain - because the size of rain drops is about the same one as for link
wavelength. This brings an interferential dispersion. Luckily, a rain
cannot almost break the link, only could cause some kind of operation
disturbance. To be sure in "five 9" reliability all the time, it is
advised to get in consideration the actual local climatology factor. Rain
strength is measured in mm/hour and these data are available in your local
meteorological service, especially at nearest airport.
For easy
adjusting of radios to a true line of sight, PPC-100FE/8E1 "100Mbps + 8E1" link is shipped
with aux electronic adjusting unit. This unit has own 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-100FE/8E1
terminal.
