| Connectivity: the art of converting, adapting, and transwithting data |
One of the main tasks of telecommunication companies
and providers is connecting consumers to the transmission
networks of providers of voice and data services.
All of these companies have to react to the different
requirements of their customers flexibly and have
to be able to provide services without running up
high costs. When making connections to the backbone
networks (SDH/PDH networks, IP/Ethernet-based networks),
network operators have to deal with all kinds of network
topologies. And the data types that have to be transwithted
are just as multifarious: from simple voice signals
to the data-intensive applications of Internet service
providers, large companies, banks and insurance companies.
Depending on the application, there are also all kinds
of data coding that have to be transwithted across
a backbone network.
There are different kinds of conversions: from electrical
to electrical,
from optical to optical or from electrical to optical:
 |
Level adaption (from
one standard to another, such as X.21 to G.703) |
|
Mechanical adaption
(Connections from one plug connection to another) |
|
Conversion of data
rates |
|
Conversion of data
coding |
Special optical/optical and electrical/optical:
|
Conversion of wavelength, |
|
Conversion of fiber
optic plugs and fiber type |
|
Expansion of transmission
ranges |
In addition to electrical/electrical signal matching,
the electrical/optical and the optical/optical fields
are two of Pandatel’s main areas, with a multitude
of solutions. Although transmissions via fiber optic
lines are much faster and have much greater capacity
than via copper lines, copper lines are still in use
for the data transmission. Copper networks are currently
dominant in the “last mile” from the
telephone company’s network to the consumer.
As investments in new infrastructures are extremely
expensive, there is a need for solutions that use
the existing network structures and interfaces between
the networks more efficiently. Copper lines can be
connected to backbone lines with converters and modems.
Thus, the adaptation, conversion, and support of various
bit rates and interfaces
ensure simple network access.

2. Point-to-point transmission solution for
banks in Singapore
The Problem: A leading telecommunication
company in Singapore offers its customers from
the banking sector a direct connection to their
data centers. The banks have to maintain double
data centers for their transactions. One of
these centers works as the primary center, the
other as a backup. The two data centers, which
are some ten kilometers apart, are to be connected
via dark fiber. Another dark fiber serves as
the backup connection. In the future, the connection
between the data centers could be upgraded from
100 Mbps to 1000 Mbps to allow a more efficient
use of the lines.
The Solution: At the headquarter, Pandatel’s
Ethernet converter ET-CM converts the Ethernet
data into optical signals that are directly
fed into the high-speed fiber optic ITU converter
FX-IG. In the backup center, another pair of
ET-CM and FX-IG are converting the signals back
to Ethernet data. The same configuration is
used to set up the redundant connection.
The Benefits: ET-CM has a simple troubleshooting
system with loopbacks, RFD and LPT features.
The optical performance of FX-IG with a budget
of up to 30dB can transwith data over distances
up to 100 km and is thus ideal for high-loss,
fiber optic cables, like dark fiber in this
case. All of the devices used can be controlled
via SNMP from a central headquarter. The introduction
of the ET-CG, a 10/100/1000 Mbps Ethernet converter,
can increase the bandwidth to 1000 Mbps if necessary.
