MARCH 24, 2009 -- Applied Micro Circuits Corp. has introduced the Yahara series of devices for next-generation optical network physical layer systems supporting 10-Gigabit Ethernet, metro, and long-haul network applications. AMCC will be promoting the Yahara family at OFC/NFOEC 2009, Booth #3015, from March 24-26 at the San Diego Convention Center.
The devices represent AMCC's fifth generation of integrated local area network (LAN), wide area network (WAN), and optical transport network (OTN) silicon technologies.
The product family extends edge and metro Carrier Ethernet features into metro and long-haul optical network applications. By providing additional modes of 10G to OTU-2 mapping features and incorporating a second 10G PHY into the Yahara product line, the company expects to provide telecom OEMs with power, space, and cost savings for OTU-2 transponder and regenerator applications.
By offering three packages supporting 10G "AnyRate" protocols, the devices are suited to various blade applications including 10G client/line cards, 10G transponders/muxponder cards, 10G regenerator cards, and 40G to 100G muxponder applications.
"The 10G market is marked by rapid technology transitions, which often results in large shifts in vendor share. The market for 10G PHY is in a rapid technology transition and several vendors are vying to establish an early leadership position," says Jag Bolaria, principal analyst with The Linley Group (search Lightwave for The Linley Group). "AMCC's Yahara product family integrates a compelling array of functions that match up well with the needs of next generation telecommunications platforms, carrier Ethernet switches, and router applications. With Yahara, AMCC is positioning itself to capitalize as the transition to optical technology expands into the metro and long-haul networks."
The Yahara product family integrates 10GbE/10G Fibre Channel (FC)/8G FC/OC-192/STM-64 to OTU-2 mapping services, FracN clock synthesizing circuitry, electronic dispersion compensation (EDC), GFEC/Enhanced FEC, and 10G SerDes functions in a single device. By eliminating the need for various external PHYs and interface bridge devices, Yahara devices enable telecom OEMs to reduce 10G OTU-2 transponder and regenerator line card power and space requirements by up to 56% and 81%, respectively, says AMCC.
The Yahara S10123 is designed for 10G OTU-2 client/line tributary metro Ethernet and switch/router applications. Its flexible system interface supports XAUI/SFI4.P2/SFI-5s protocols and enables the direct connection to network processors, 10GbE switches, 10G framers, and 10G MACs. The 10G line XFI interface enables the direct connection to XFP and SFP+ optic modules. The Yahara S10123 is packaged in a 19x19-sq.-mm plastic ball grid array.
In the Yahara S10124, a XAUI/SFI4.P2/SFI-5s system interface and a dedicated 10G XFI line interface support a separate and dedicated 10G XFI client interface as well as a 16-bit parallel SFI4.P1 interface, providing flexibility for use on either the client or line side of the device. The S10124 is appropriate for 10G OTU-2 client/line tributary cards, transponder, and regenerator applications and supports 10G XFP/SFP+ and 10G MSA modules. The S10124 is packaged in a 25x25 plastic ball grid array.
The Yahara S10126 device is designed for the optical networking industry's continuing migration to small-form-factor serial 10G optic modules and 10G serial backplanes. It is packaged in a 19x19 plastic ball grid array and supports two serial 10G interfaces that are XFP/SFP+ module compliant, enabling a small footprint for 10G transponder applications, serial 10G backplane applications, and 10x100G muxponder applications.
The entire family supports a 10G GMP mapping mode that enables 10G client signals to be mapped into a generic ODU-2 frame at a common clock rate that can feed a 100G muxponder device. This mapping feature provides a clean and easily routable interface to both the client side XFP/SFP+ optic module and to the100G muxponder device.
Integrated ITU G.709 FEC (GFEC) and AMCC's Enhanced FEC (ITU G.975.1.I4) enable metro and long-haul transmission of 10GbE over OTN networks in low OSNR environments. The FEC features also compensate for channel impairments, enabling narrow channel spacing of 25 GHz for DWDM systems.
The Yahara products are industrial temperature compliant (-40° to +85°C) and will begin sampling to alpha customers in 2Q09.
