OTS 4040 DPSK Transponder Technical Specifications The OTS-4040 line card offers the following capabilities: Transparent transport of OC-768/STM-256/OTU-3 service interfaces Supports channelized or concatenated framing Full C or L band tunable laser and broadband receiver for flexible wavelength provisioning and minimized sparing costs Enhanced Forward Error Correction with 8.5dB net equivalent coding gain for optimized reach up to 2,000km Spectrally efficient for operation at 50GHz channel spacing and through multiple cascaded [R]OADMs Tunable -19 to 0 dBm transmit output power and -18 to 0 dBm receive input power range for easy interoperability with existing DWDM systems Common CD and PMD link engineering rules as 10Gbps when deployed in conjunction with OTS-4540 PMDC Applications The OTS-4040 transponder enables cost-effective transport of OC-768/STM-256/OTU-3 client services into a 40Gbps DWDM wavelength for metro, regional and long-haul networks. It can be deployed in retrofit applications on 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 50GHz channel spacing facilitates simplified 10Gbps and 40Gbps 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.
