V.35 Optical modem


описание характеристика решения документация Дилеры
  • transmits Nx64K V.35 signal through fiber to realize long-distance transmission of data and can extend V.35 channel of ATM or DDN with OFCC-E1.
  • unique two-row indicating lamps (upper row indicating local status, lower row indicating far-end status);
  • based on self-copyright IC with high content software (core chip based on its own software);
  • truly realize random choice of time slots to compose Nx64K (N=1—32) data channel;
  • provides 3 kinds of loop-return function, namely V.35 self-looping at local end, V.35 looping from remote-end to local end, and ordering remote-end V.35 loop to local end;
  • has the function of pseudo-random code testing, which brings great convenience for installation, debugging and maintenance of equipment;
  • can realize rate regulation of remote-end equipment (in submissive clock status) when local equipment is in master clock status;
  • V.35 fiber modem can be used with E1 fiber modem in pair to save one E1/V35 protocol converter;
  • the rate of V.35 interface is Nx64K (N=1—32), and it can be tail-connected with other DCE equipment;
  • provides SNMP network management.
V.35 interface:
  • Rate: 2.048Mbp/s±50ppm
  • Interface characteristic: satisfies V.35 standard
  • Connector: DB25 (male of female for option)
  • Connecting mode: DCE
  • Clock type: G.703 recovery clock, internal/external clock
Optical interface parameter:
  • Optical interface: SC/FC
  • Optical wavelength: 850nm/1310nm for multi- mode optical fiber,
  • 1310nm/1550nm for single-mode optical fiber
  • Transmitting range: multi-mode 2 Km, single-mode 40Km, single-mode 60 Km, single-mode 120Km
