Chapter 1. INTRODUCTION
1.1 Overview
The CLO-10 is Comtech EF Data’s Link Optimizer incorporating DoubleTalk™ Carrier-in-Carrier
®
technology. The CLO-10 allows transmit (Tx) and receive (Rx) carriers in a full-duplex link to use
the same transponder segment via advanced signal processing techniques. The result is a reduction
in bandwidth required for the duplex link by as much as 50%.
The CLO-10 operates on the 70/140 MHz IF band, which facilitates retrofitting into existing
systems. The unit is installed in the IF path between the modem and the up/down converters. The
CLO-10 does not require prior knowledge of the signals to be processed (i.e., modulation type,
FEC, etc) other than the bandwidth and center frequency of the desired signal.
Figure 1-1 shows the CLO-10 Link Optimizer. The Link Optimizer can be configured for two
versions – the standard CLO-10-1 (shown), and the CLO-10-2, which features the optional
redundancy hardware upgrade.

For the purpose of brevity, the Link Optimizer is referred to throughout this manual as the CLO-10.
With the exception of redundancy operations, all content in this manual is applicable to both the CLO-
10-1 and CLO-10-2 models; the CLO-10-2’s added functionality is explained in detail in
