PDH 8E1-SM20-1310 & 8E1-SM20-1550 converters for transmission of 8 flows E1 via one single-mode optical fiber at distance up to 20 km (different variants of performance for 10, 20, 40 and 60 km are possible). Media converters operate as per point-point circuit. Reception and transmission are performed at different lengths of waves. Media converters operate as per point-point circuit. They are performed in 19” case and have double supply system -48 V and 220 V. There is a light system  indication of emergencies and various modes of operation that provides quick diagnostics.

Features

  • 8 digital interfaces as per 2.048 Mb/s (E1 flow) per one fiber;
  • Control interface for remote centralized monitoring with maintenance of remote port
  • One additional phone line (as per request)
  • One additional Fast Ethernet channel 10/100 (as per request)
  • Flexibility of power supply selection 175..250 V AC or -48 V DC
  • 1U/19” metal case
  • Synchronization recovery circuit DPLL approved for 2.048 Mb/s channel
  • LED indication
  • Equipment operates as WDM pair

LED indication:
Indication of optical signal of E1 flow at local device
Indication of optical signal of remote device
Return loop indicator
Out-of-order call indicator
Power supply indicator

DIP switches on the front panel:

  • testing of equipment and arranging remote loop as per E1
  • testing of optical communication line and arranging loop via optical channel (TX-RX)
  • connection and disconnection of acoustic emergency signal
