E2, Opti-Multiplexer
Technical Specification
|
E2, Opti-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 any signal repeaters up to a
distance of over 50 KM.
The multiplexer / demultiplexer also does the reverse
processing i.e. demultiplexing a received optical signal into
four 2Mbps E1 tributaries. |
Single Mode Optical Fiber pair.
On the de-multiplex side, it receives the optical signal and de-multiplexes
it into 4, electrical E1 signals.
