VCL - E2, Optical Multiplexer (4E1)
is an Integrated OLTE and multiplexer / demultiplexer unit,
based on PDH (Plesiochronous Digital Hierarchy) technology. It
multiplexes four 2.048 Mbps (hereafter referred to 2Mbps) E1
tributaries into a single 8 Mbps, E2 stream and then
transports it as an optical signal on a Single Mode, 1300nm
optical fiber cable, without the use of ant signal repeaters
up to a distance of over 50 KM (Optical Loss Budget
³
30dBm). The muldex also does the reverse processing i.e.
demultiplexing a received optical signal into four 2Mbps E1
tributaries. |

External Interfaces & Connectors
VCL Opti-Multiplexer
unit provides the following interfaces to the external world:
- 4, Primary rate 2Mbps & 120 Ohms
balanced E1 interfaces
- 1300nm, Single Mode optical
fiber interface, Tx and Rx through FC/PC Connectors
- -48V input for on-board power
supply
- RS232 interface for connection
to Network Management System, used for configuration and
monitoring of the Opti-Multiplexer system.
- 2 External alarm extensions for
visual and audible alarms.
These alarm
condition except PSU failure, are extended to the bay top by two
potential free make contacts. These alarms, optionally, are also
transmitted over the RS232C serial link.
