OTS 4011 DPSK Muxponder
Technical Specifications
The OTS-4011 line card offers the following capabilities:
- Transparent transport of four asynchronous 10 Gbps service interfaces
- Any mix of OC-192/STM-64, OTU-2 and 10GE LAN/WAN PHY client interfaces
- 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 50 GHz channel spacing and through multiple cascaded [R]OADMs
- Tunable -19 to 0 dBm transmit output power and -18 to 0dBm receive input power range for easy interoperability with existing DWDM systems
- Integrated Tunable Dispersion Compensator enabling common CD link engineering as 10Gbps
- Common PMD link engineering rules as 10Gbps when deployed in conjunction with the OTS-4540 PMDC
Applications
The OTS-4011 multiplexing transponder enables cost-effective aggregation of 10 Gbps client services into a 40 Gbps DWDM wavelength for metro, regional and long-haul networks. It can be deployed in retrofit applications into existing 10 Gbps 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 50 GHz ITU grid and operation over multiple cascaded [R]OADMs.
Operation at 50 GHz channel spacing facilitates simplified 10 Gbps and 40 Gbps multi-haul networking. No special banding structure or alternating 10 Gbps and 40 Gbps channel plan is required to support mixed 10Gbps and 40 Gbps DWDM networking. 10 Gbps or 40 Gbps wavelengths are completely interchangeable at any point in the network
Flexibility
The Opnext OTS-4011 networking allows any of the four 10 Gbps clients to be software provisioned to OC-192/STM-64, OTU-2 or 10GE LAN/WAN PHY, in any permutation. Ports can be provisioned to the required protocol when the 10 Gbps circuit is placed into service, irrespective of what traffic is running on the other 3 clients. The ability to mix different 10Gbps protocols within a single 40 Gbps DWDM wavelength minimizes upfront cost and stranded bandwidth in the network.
