OTS 4011 PSBT Muxponder
Technical Specifications
The OTS-4011 line card offers the following capabilities:
- Transparent transport of four asynchronous 10Gbps service interfaces
- Any mix of OC-192/STM-64 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 1,000km
- Spectrally efficient 22GHz FWHM bandwidth for operation at 50GHz channel spacing and through multiple (>10) cascaded [R]OADMs
- -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 10Gbps when deployed in conjunction with the OTS-4520 TDCM and OTS-4540 PMDCM
Applications
The OTS-4011 multiplexing transponder enables cost-effective aggregation of 10Gbps client services into a 40Gbps DWDM wavelength 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 Phase-Shaped Binary Transmission (PSBT) modulation format enables operation on the 50GHz ITU grid and operation over multiple cascaded [R]OADMs with negligible penalty.
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.
Flexibility
The StrataLight OTS-4011 networking allows any of the four 10Gbps clients to be software provisioned to OC-192/STM-64 or 10GE LAN/WAN PHY, in any permutation. Ports can be provisioned to the required protocol when the 10Gbps 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 40Gbps DWDM wavelength minimizes upfront cost and stranded bandwidth in the network.
A major advantage of using field pluggable XFP transceivers on the client interfaces is that they come in all flavors necessary to support many different applications and client reach requirements. From ultra low cost 300m multi-mode fiber interfaces to integrated DWDM, the OTS-4011 can support all possible client interconnection options directly off the 40Gbps transponder without requiring additional costly OEO transponders.
