Semiconductor provider PMC has added a second-generation HyPHY OTN processor family it says enables Metro OTN.

“With PMC’s HyPHY 20Gflex and HyPHY 10Gflex, Metro OTN doubles packet efficiency and delivers the multiservice capabilities and scalability required for metro transport networks worldwide to cope with explosive growth in packet traffic,” the company adds. “Service providers can now reduce opex with an unprecedented level of network resource optimization and management for Ethernet, SAN and video services.”

The HyPHY Flex devices are ODU0-channelized Metro OTN processors that support the newly approved OIF-compliant OTN-over-Packet Fabric system interface.

Based on a set of client-agnostic and rate-agile SERDES for both Small Form Factor Pluggable (SFP) and 10 Gigabit Pluggable (XFP/SFP+) optics, the PM5450 HyPHY 20Gflex delivers 16xSFP and 2x10G XFP/SFP+ interfaces along with Any-Port, Any-Rate, and Any-Service flexibility for the transport of Carrier Ethernet, IP/MPLS, SONET/SDH, SAN, and video over an OTN infrastructure. A PM5456 HyPHY 10Gflex version also is available for lower-density applications.

Both platforms offer the following features:

>> True Any-Port, Any-Rate and Any-Service flexibility: Independent, rate-agile SERDES with integrated PLLs allows operation from a single reference, helping to eliminate external timing components and reducing cost, power and footprint.

>> Carrier Ethernet transport: Transparent, semi-transparent and MAC-terminated transport of Ethernet, with onboard FE/GE and 10GE PCS/MACs, including support for Timing over Packet (IEEE 1588v2), Synchronous Ethernet (SyncE), and Ethernet Link OAM (IEEE 802.3ah).

>> Field-proved interoperability with OIF OTN-over-packet-fabric standard: PMC’s OTN Phase Signaling Algorithm (OPSA) and Constant Bit Rate Interface (CBRI) technology provide an OIF-compliant and glueless interface to off-the-shelf or proprietary fabrics for fine-grain OTN switching.

>> Integrated ODU0/ODUflex-granular framing, mapping and switching: As much as 40G of OTN framing and 100G of OTN switching in a single chip, with the industry’s first on-board support for PTP (IEEE 1588v2) over OTN.

>> Single-chip for DWDM muxponder and transponder as well as OTN switching modes of operation.

>> Support for OTN fault restoration, resiliency and protection switching: Integration of supplementary OTN framers, monitoring and alarm insertion points to enable such flexible protection switching schemes as Sub-Network Connection Protection (SNCP) for point-to-point, ring or mesh topologies.

>> Flexible Interlaken and XAUI packet interface: Enables glueless interface to off-the-shelf network processors and Ethernet switches for implementation of hybrid multiservice OTN and Carrier Ethernet cards.

The PM5450 HyPHY 20Gflex and PM5456 HyPHY 10Gflex devices are sampling now.
