PMC-Sierra Announces HyPHY-Based ODU0 Reference Design for Gigabit Ethernet over OTN

PMC-Sierra, a provider of Internet infrastructure semiconductor solutions, announced a complete reference design for its HyPHY chipset that supports standards-based transport of Ethernet-based services over the Optical Transport Network or "OTN."

HyPHY chipset from PMC-Sierra (News - Alert) integrates support for mapping and multiplexing of GEs into sub-ODU1 or 2.488Gbit/s containers. It enables Any-Service, Any-Rate, Any-Port for ROADMs, OTPs and u-OTPs, the company said.

The new PM5423-KIT ODU0 reference design leverages HyPHY's flexible packet interfaces and unique OTN Payload Tributary Mapping or "OPTM" technology.

Company officials said the new design supports the newly defined OTN mapping modes, including Transparent GE mapping and de-mapping into/from ODU0 via GMP and ITU-T ODU0 multiplexing and de-multiplexing into/from higher order ODUks.

The ITU-T G.709 version 3 specifies direct mapping of Gigabit Ethernet or "GE" to the OTN layer by defining a new container for the smallest Optical Data Unit or "ODU," ODU0 with 1.238 Gbit/s, ensuring complete timing transparency and bandwidth efficiency of Ethernet-based client signals, the company said.

The reference design enables cost-optimized Layer 1 OTN networks with full support for Ethernet network timing distribution, a critical requirement for wireless backhaul applications.

"The exponential growth in Ethernet-based wireless backhaul, driven by 3G and LTE (News - Alert) deployments, is accelerating the need for an efficient mechanism for GE transport over OTN," Travis Karr, vice president and general manager of PMC-Sierra's Communication Products Division, said.

"This reference design enhances our HyPHY product family for multi-service convergence over OTN and provides a time-to-market advantage for our customers," Karr added.

PMC-Sierra's ODU0 reference design can be used with either the PM5420 HyPHY 20G or PM5426 HyPHY 10G device. It includes a complete collateral suite, including a hardware reference design for evaluation, design specification documentation, and FPGA source RTL for integration.

HyPHY 20G delivers high capacity framing, mapping and multiplexing of Carrier Ethernet, SAN, OTN, transparent bit services such as video, and SONET/SDH to allow carriers to reduce the number of network elements, while incrementally adding bandwidth or changing service mix per node without forklift upgrades, according to company officials.

The platform also provides client-agnostic, rate-agile Small Form-Factor Pluggable (SFP) and 10 Gigabit pluggable or "XFP or SFP+" interfaces and a set of flexible system interfaces for networking to a variety of switch fabric architectures.

While HyPHY 10G provides a lower density option for optical platforms, it integrates high-performance mixed-signal analog and media access control, along with numerous innovative features such as True Per-Port Rate and Protocol Flexibility; Multi-Service Muxponder; Efficient Fiber Utilization; and Carrier Ethernet.

The PM5423-KIT ODU0 FPGA reference design, as well as the PM5420 HyPHY 20G and PM5426 HyPHY 10G devices, is currently available, the company said.
