OTS-4400 DPSK Regenerator
Technical Specifications
The OTS-4400 line card offers the following capabilities:
- Cost-effective 3R, uni-directional, OEO regeneration
- Transparent regeneration of OC-768/STM-256/OTU-3 or quad 10Gbps service interfaces
- Supports channelized or concatenated framing
- Full C or L band tunable laser and broadband receiver for flexible wavelength provisioning, minimized sparing costs and wavelength translation capabilities
- Enhanced Forward Error Correction with 8.5dB net equivalent coding gain for optimized reach up to 2,000 km
- Spectrally efficient for operation at 50GHz channel spacing and through multiple cascaded [R]OADMs
- Tunable -19 to 0dBm transmit output power and -18 to 0dBm receive input power range for easy interoperability with existing DWDM systems
- Common CD and PMD link engineering rules as 10 Gbps when deployed in conjunction with OTS-4540 PMDC
Applications
The OTS-4400 regenerator enables cost-effective 3R OEO regeneration capability of OC-768/STM-256/OTU-3 or quad 10Gbps client interfaces for metro, regional and long-haul networks. It can be deployed in retrofit applications into existing 10Gbps DWDM networks, or to maximize capacity for greenfield deployments. For both applications, the use of spectrally efficient Differential Phase Shift Keying Transmission (DPSK) modulation format enables operation on the 50GHz ITU grid and operation over multiple cascaded [R]OADMs.
Operation at 50 GHz channel spacing facilitates simplified 10Gbps and 40 Gbps multi-haul networking. No special banding structure or alternating 10Gbps and 40Gbps channel plan is required to support mixed 10Gbps and 40Gbps DWDM networking. 10Gbps or 40Gbps wavelengths are completely interchangeable at any point in the network.
