2.5Gb/s (STS-48/STS-48c/STM-16) with OC-192 Support SONET/SDH STS-1 Grooming Switch
Product Summary
GENERAL DESCRIPTION
VC2002 SONET/SDH Grooming Switch accepts STS-48 input streams generates STS-48 output streams STS-192 streams that have been demultiplexed 1:4). allows each STS-1 component each input stream directed arbitrary STS-1 slot arbitrary output stream. effect, 3456 3456 STS-1 switch. VC2002 also supports STS192c mode.
Table VC2002 Features Benefits
VC2002 utilizes Velio's high-speed Gigacores (SERializer DESerializer cores) 2.488Gb/s serial signals. user-selectable features each GigaCore address Inter-Symbol Interference (ISI), help ensure signal integrity multi-gigabit speeds. Most importantly, integrated 2.488Gb/s Gigacores enable VC2002 drive electrical backplanes directly, without need external transceivers.
FEATURES 72x72 STS-48/STS-48c (2.48 Gb/s) 18x18 STS-192/STS-192c (9.95 Gb/s de-multiplexed 1:4) Cross-Connect Power Consumption Cross-Connect Switching STS-1 Granularity (3456 3456) SONET/SDH Input Processing channel on-chip Clock Recovery/Demultiplexer Frame detection, byte monitoring SONET/SDH Output Processing channel On-Chip Clock Generation/Multiplexer Single Byte Insertion within frame diagnostics High-Speed Serial with Programmable Output Voltage Swing Adjustable Pre-Emphasis Serial Outputs Optional Receiver Equalization Serial Inputs 37.5 37.5
