Modems

 

Vrinda has developed following Modems (Modulator & Demodulator) for meeting different requirements of customers.

 

SHDSL Modem (VTLM)

SHDSL modems are targeted to meet  typical carrier and access network needs as well as industrial requirements with data rates from 72 kbps up to 5704 Mbps using copper connectors.

 

FO Modem (VTFOM)

FO Modems are capable of data transfer rates from 72 Kbps up to 5.6 Mbps over fiber optic cables.

 

IQ Modem (VTIQM)

Wide band IQ Modems are capable of operating over 1.5 GHz to 2.5 GHz and with an Local Oscillator (L.O) of 2.0 GHz.  They deliver wideband ( 0-500MHz) I&Q output in demodulator section and provide RF output 1.5 to 2.5GHz with 0 to 500 MHz (I&Q) input in modulator section.

 

BSPK/QPSK Modem (VTQPSK)

Narrow Band Satellite Modems work with standard 70 MHz or 140 MHz IF with BPSK / QPSK modulation.  The data rates can change from 2.88 Kbps to 19.6 Kbps.  They are suitable for narrow band voice / data applications    over satellite links.
