Overview

Comtech EF Data’s CLO-10 Link Optimizer provides up to 16.384 MHz of modem agnostic bandwidth compression (or up to 18.2 MHz when using Comtech EF Data’s CDM-710G High-Speed Satellite Modem with Adaptive Equalizer) that can be used to optimize one or more two-way satellite links.

The CLO-10 is based on the DoubleTalk Carrier-in-Carrier bandwidth compression technology that allows for two-way satellite links to be transmitted concurrently in the same transponder space, thereby providing significant savings in space segment.

Operating at 70/140 MHz IF, the CLO-10 can be easily deployed between the frequency up/down converters and the modem or the transceiver and the modem.

Specifications
Cancellation Bandwidth Up to 16.384 MHz / 18.2 MHz
(when used with CDM-710G with Adaptive Equalizer)
Signal Cancellation 30 dB minimum with like carriers
BER Degradation 0.3 dB (typical) when used with Comtech EF Data Modems
Interfering carrier(s) at or below +10 dBc
Adjacent carrier(s) at or below +13 dBc
Input Frequency 50 MHz – 90 MHz or 100 MHz – 180 MHz
1 kHz steps
Input Level, Uplink
(From Modem)
0 to -40 dBm reference carrier
+10 dBc maximum composite
Input Level, Downlink
(From Down Converter)
-105 dBm + 10 log (BW) to -70 dBm + 10 log (BW)
BW is input signal processing bandwidth, usually set to the symbol rate of the desired signal 94 - 10 log (BW) dBc maximum composite
+20 dBm absolute maximum composite
Output Frequency 50 MHz – 90 MHz or 100 MHz – 180 MHz
1 kHz steps
Output Level, Uplink
(To Up Converter)
Input level (uplink) - 1 ± 0.5dB
Output Level, Downlink
(To Modem)
-20 to -30 dBm for C/I of ± 10dB
Uplink - Output spurs, Stability, Spectrum Set by the modem
Frequency Reference Selectable
Internal Reference 10 MHz, ± 1.5 ppm stability
External Ref
(BNC Female)
None (off), 1, 2, 5, or 10 MHz, internally phase locked.
Input is 50 / 75 Ω compatible with 0.5 to
4.0 V pp sine or square wave. Requires high stability source.
Input/Output Impedance 75 Ω
Unit Fault Form C relay
Redundancy 1:1 and 1:N
(Covered by US Patent 5,666,646 - Radio frequency (RF) converter system with distributed protection switching and method therefore)
Satellite Restrictions Satellite in “loop-back” mode (i.e. Transmit station must be able to receive itself)
“Non-processing” satellite (i.e. does not demodulate/remodulate the signal)
