This section provides a hardware description of the 1643 AM Add-Drop-Multiplexer.
Hardware description 1643 AM
The 1643 AM is a compact and cost-effective STM-1 or STM-4 Add-Drop-Multiplexer
designed to be installed at the customer’s premises for fiber-to-the-business
applications. Its space-efficient design allows for horizontal or vertical wall- or
rack-mounting within controlled or non controlled environment locations (for example
interior closet) or in street cabinets. Please refer to the 1643 AM / 1643 AMS
Installation Guide for details.
The unit has the following characteristics:
• Dimensions (H x W x D) 83 x 439 x 295 mm (without the wall or rack mounting
system)
• main board including:
– One or two STM-1 or two STM-4 optical aggregate line interface pairs
(transmit/receive) with a universal connector type allowing SC, FC/PC, ST
connector types without external optical cable conversion.
– Sixteen 2 Mbit/s electrical tributary interfaces with RJ45 connectors suitable for
symmetrical twisted pair cables with an impedance of 120 Ω or suitable for
coaxial cables with an impedance of 75 Ω
• F-interface (RJ45) complying with V.10/RS-232 for the Craft Interface Terminal
(ITM-CIT)
• Q-LAN interface to connect to the EMS or to other NEs is available with an RJ-45
(LAN-10BaseT) connector
• External Synchronization Output at 2048 kHz (SYNC-OUT) with RJ45 connector
suitable for symmetrical twisted pair cable with an impedance of 120 Ω or coaxial
cable with an impedance of 75 Ω
• Two LEDs (Red, Green) to indicate the status of the unit.
• Four Miscellaneous Discrete Inputs (MDIs) to read the status of external alarm
points, and four Miscellaneous Discrete Outputs (MDOs) to drive external devices
are available from a 25 pin male Sub-D connector.
• The possibility of power supply of the equipment is DC power supply or AC power
supply:
– DC power supply is connected to a 9-point male Sub-D 9 connector
– AC power supply is connected to an AC socket (IEC 60320 standard).
The power cord with the appropriate power plug for the country of use is not
supplied.
