Slide 1
E2 , 2Mbps x 4 - Opti Multiplexer
Product Overview
• VCL-E2, Opti Multiplexer (4E1) is an
Integrated OLTE and multiplexer/
demultiplexer unit, based on PDH
(Plesiochronous Digital Hierarchy)
technology
• It multiplexes four 2.048Mbps (hereafter referred to 2Mbps) E1 tributaries into
a single 8Mbps, 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 50KM (optical loss budget 30dBm)
• On the demultiplex side, it receives the optical signal and demultiplexes it into
4, electrical E1 signals
• This device provides data and extracted jitter free clock meeting the G.703
standards
• These include loss of signal at E1, loss of signal at E2, loss of frame sync at E2,
detection of AIS at E2 and bit error exceeding 1 in 1000
VCL-E2, Opti Multiplexer is available in
• 1310nm
• 1550nm.
