Two 10G EPON reference designs, the PAS8001 OLT and PAS9001 ONT, have been created for central office optical line terminals (OLTs) and premises optical network units (ONUs). The chip functions in each design will reside on a pair of FPGAs and will support asymmetric (10-Gbit/sec downstream, 1-Gbit/sec upstream) transmission along the lines of the specifications expected to be contained in the 10G EPON standard. The chips also support the XFI interface used with XFP optical transceivers. The devices offer auto-detect, standard encryption, and backwards-compatible dynamic bandwidth allocation and include optical transceivers.

The Radian System processes bare optical fibers and allows fibers to be polished at user-selectable angles for R&D applications and production. A real-time video system actively monitors the polishing process from start to finish. The inspection module permits in-line viewing of the polished fibers to ensure surface quality. Adapters are available for a variety of fiber types and diameters. PM fiber can also be aligned and polished in the system.

New network interface devices (NIDs) are carrier-grade, Metro Ethernet Forum certified components designed for use in telco, cable, and utility networks to support copper-to-fiber, fiber-to-fiber, and copper-to-copper demarcation with fixed copper, fiber, or small-form-pluggable ports. The product line includes the 10/100M2 for 10/100 UTP to 100Fx fiber applications; 2FXM2 for 100Fx fiber-to-fiber applications; GX/TM2 for 10/100/1000 UTP to UTP and UTP to Gigabit Fiber applications; and 2GXM2 for Gigabit fiber-to-fiber applications. All four models provide fiber access for Carrier Ethernet services with MEF 9 and MEF 14 certified compliant demarcation and support IEEE 802.3ah specifications. The devices also support Iometrix cNode end-to-end fault detection and performance monitoring.Omnitron Systems Technology Inc., www.omnitron-systems.com
The Layered Services Management tool addresses the challenges of managing metro and regional networks. Its features were developed to augment the SN 9000 intelligent multiservice switch, a carrier-grade platform that integrates multiple functions, including low-order and high-order switching, add/drop multiplexing, advanced Ethernet services, and integrated optical transport, in a single system. The tool features flexible, partitioned views of pertinent multilayer service information, proactive alarming through intelligent correlation of network and service layer information, simplified troubleshooting to aid in identifying, diagnosing, and prioritizing performance issues, and improved visibility and control to maximize end-to-end capacity and resource utilization.Sycamore Networks Inc., www.sycamorenet.com
New functionality for the T-BERD/MTS-8000 transport module combines 4G and 10G Fibre Channel test support with traditional transport test capabilities such as SONET/SDH, Ethernet, and OTN. The functionality is engineered to address the growing demands for installation and troubleshooting of Fibre Channel services in metro networks. New features include support for Layer 4 TCP simulation for troubleshooting next-generation Ethernet/IP services, Ethernet client testing capability for 11.05- and 11.1-Gbit/sec OTN networks, and support for the installation and troubleshooting of IPTV networks.

The wavelength blocker is designed for optical add/drop multiplexer (OADM) applications in next-generation optical communication networks. The internal optical block has no moving parts and the package is based on a hermetic sealing structure for high operational stability and long-term reliability. Other features of the subsystem include C-band or L-band operation at 100- or 50-GHz spacing, wide passband with flat-topped channel profile, channel-by-channel attenuation and blocking, and high extinction ratio. In addition to its application for reconfigurable OADMs, the device also can be used for network management (protection and restoration) and dynamic channel power equalization.Santec Corp., www.santec.com
An optical device for FTTH bidirectional transmission has been developed and marketed under the SXT family. Modules include the GPON ONT diplexer, ITU G.984.2 Class B+ (SXT4472); the BOSA, IEEE802.3ah (SXT6030); and the GPON ONU triplexer, ITU G.984.2 Class B+ (SXT9241). The SXT4472 series corresponds with the burst mode signal that is required at GPON OLTs and is equipped with the reset terminal pin for responding to the burst signal within a very short period. The SXT4472 and 9241 series utilize in-house package technology. All of the optical devices are fully RoHS compliant.
