Main features
- Multiservice SDH optical transport system for voice and data transmission at STM-1 (155 Mbit/s) and STM-4 (622 Mbit/s) level
- Optical line interfaces 622 Mbit/s and 155 Mbit/s provide transmission on singlemode optical fibre at 1310 nm for section length up to 50 km, or at 1550 nm for section length up to 100 km
- Plug-in SFP optical or electrical tranceivers, provide STM-1 or STM-4 interfaces on the same unit
- WDM option-single fibre transmission (1310 and 1550 nm), passive optical filter
- CWDM option-single fibre transmission (1490, 1510, 1530 and 1550 nm), passive optical filter
- Full non blocking cross-connect matrix, capacity 16x16 VC-4 (2.5 Gb) up to VC12 level
- PDH tributary interfaces for 2 Mbit/s and 34 Mbit/s
- Ethernet over SDH via VCAT/GFP/LCAS technologies
- Static and dynamic Ethernet traffic capacity adjustment, LCAS procedure
- Line protection at multiplex section, 1+1 MSP, higher order path or lower order path protection (VC12, VC3, VC4), subnetwork protection SNCP
- Advanced fault diagnosis (integrated BER tester, etc)
- Unit’s configuration parameters are stored in backplane memory, that enables “plug & play” change of units
- SONET option (OC-12/OC-3, T1, T3) is software configurable
- OTS622 has been designed in compliance with new ITU-T recommendation and ETSI standards
