opitcal modem Description

Optical modem
The series optical modem developed and producted by Global Tech includes:E1 optical modem,V.35 optic modem,and Ethernet optic modem.
E1optical modem
1. Auto detecting the rate of exterior clock and lockingin.
2. High quality laser apparatus with well optic characteristic,electrical characteristic,temperature stability and monochromaticity assure reliable data transmission
3. Support transparency transmit to E1framed signal
4. Introduce DPLL technology to resume no dithering clock from optic signal
5. Provide diagnostic function for selftesting which can achieve the integrality testing of the link
6. Single、double optic fiber transmitting mode selectable
7. Use inner switch power supply to provide protection against overvoltage,overcurrent,well in electromagnetic shielding
8. Provide standlone equipment,19 inches mounting rack and card inserted equipment
