Level 4 devices support 10Gbit Ethernet
PMC-Sierra has unveiled the Xenon (10Gbit Ethernet for optical networks) family of clock recovery and concatenated PHY/framer devices.
PMC-Sierra has unveiled the Xenon (10Gbit Ethernet for optical networks) family of clock recovery and concatenated PHY/framer devices designed to enable the convergence of WAN-based OC-192 ATM/POS, Gigabit Ethernet (GE) and 10Gbit Ethernet (10GE) services in the metro Xenon devices are compatible with multiple ITU, IEEE, OIF and ATM Forum standards offering broad support for 10Gbit optical modules and protocol framing modes

Hardware interoperability accelerates optical nets
PMC-Sierra and Altera Corp have announced the successful interoperability of PMC-Sierra's Xenon family of devices and Altera's POS-PHY Level 4-compatible Apex II devices.
It is the first family to use the Saturn Development Group's highly optimised 10Gbit POS-PHY Level 4 standard system interface to terminate traffic running over 10GE WAN, 10GE LAN, 10-port GE, OC-192c ATM/POS and four-channel OC-48c ATM/POS fibre links.
The highly integrated Xenon family represents PMC-Sierra's fourth phase of a comprehensive 10Gbit strategy for PMC-Sierra which includes the Chess-II channelised crossconnect chipset architecture, the multigigabit SERDES interconnect family and the 10Gbit strategic alliance with MultiLink Technology Corp.
The Xenon device family enables 10Gbit metro equipment to support the necessary optical module standard interfaces with a single port card design.

The SFI-4 (SERDES-to-framer interface level 4) 16bit, 622Mbit/s optical module interface, standardised by the OIF, is widely deployed in all the current OC-192 SONET/SDH, ATM and POS systems using optics from very short reach (VSR) to long haul.
10-port GE applications require a bank of ten small-form-factor 1.25Gbit/s optics.
Additionally, the IEEE P802.3ae 10 Gigabit Ethernet Working Group has standardised the XSBI (10Gbit sixteen-bit interface) 16bit, 645Mbit/s optical module interface.
It is a slightly faster version of SFI-4 designed for current 10GE LAN PHY and 10GE WAN PHY applications using serial 10Gbit optics.
PMC-Sierra pioneered the XSBI optical module interface standard within IEEE P802.3ae.
The S PM5390 S/UNI-9953 (10 GE LAN/WAN PHY and OC-192 POS/ATM concatenated PL4 framer) is the Xenon flagship product.
It is the industry's only framer device integrating six different 10Gbit standard PHY/framing modes.
The S/UNI-9953 supports the SFI-4 and XSBI 10Gbit standard optical module interfaces.
All PMC-Sierra's 10Gbit S/UNI PHY/framers incorporate the POS-PHY Level 4 system-side interface.
For SONET/SDH applications, the S/UNI-9953 provides both ATM and POS functionality at both single-channel OC-192c and quad-channel OC-48c port densities.
For 10GE applications it provides both 10GE LAN PHY and 10GE WAN PHY functionality with embedded 10Gbit media access controller (10GMAC), physical coding sublayer (PCS) and WAN interface sublayer (WIS).
PMC-Sierra is the editor for the IEEE P802.3ae WIS (clause 50).
The S PM5392 S/UNI-9953-POS (OC-192 POS/ATM concatenated PL4 framer) is the industry's highest density concatenated POS-PHY Level 4 framer for SONET/SDH applications.
It provides both ATM and POS functionality at both single-channel OC-192c and quad-channel OC-48c port densities.
A complete quad-channel OC-48c port card design can be achieved with only two chips by using either the S/UNI-9953 or S/UNI-9953-POS with PM5395 CRSU-4x2488, the industry's highest density SONET/SDH clock recovery synthesis and SERDES device.
The S PM3392 S/UNI-1x10 GE (10 GE LAN PHY with PL4) is the industry's first cost- and board-space optimised single-channel 10GE LAN PHY device with embedded 10GMAC, PCS and POS-PHY Level 4 functionality.
It is ideal for edge/core router, enterprise switch and multiservice provisioning platform applications where standard or proprietary processing of higher layers is required.
And the S PM3388 S/UNI-10xGE (10-port GE PHY with PL4) is the industry's first high-density 10-port Gigabit Ethernet PHY device with embedded standard Gigabit MAC, PCS, serialiser/deserialiser, and POS-PHY Level 4 functionality for edge router and POP switch applications.
All Xenon devices offer industrial temperature range operation from -40 to +85C along with complete access to SONET/SDH overhead bytes.
Comprehensive statistics for GE and both 10GE LAN PHY (RMON, SNMP) and 10GE WAN PHY (SONET OAM) applications provide for highly increased network management support.
To bring a more stringent and dynamic level of service provisioning not traditionally characteristic with Ethernet, the Xenon 10Gbit family integrates highly differentiated GMACs and 10GMACs supporting larger packet sizes such as 9.6Kbyte jumbo frames.
Enhanced on-chip buffering is provided allowing for up to 5km of lossless flow control per link to prevent packet drop due to network congestion.
