Mux-VOA moduleThis integrated multiplexer and variable optical attenuator (VOA) module combines 80 optical functions on a single silicon chip, reducing system complexity and cutting space requirements. Manufactured using the company's ASOC technology, the product combines a 40-channel arrayed-waveguide-grating multiplexer with a 40-channel VOA. This combination gives full control of the power level in each optical channel, allowing network designers and integrators to achieve maximum unrepeated link lengths. The module comes with full internal electronics, including a microprocessor control function, offering customers the opportunity to rapidly integrate the device into end equipment.Bookham Technology, Abingdon, Oxfordshire, UK

Fiber-optic link
A 10-Gbit/sec very-short-reach optical interconnect IC, the VSC7166 integrates transmitter and receiver functions onto a single IC. The device is used to interface SONET OC-192 framers with parallel optical modules, allowing designers to connect networking equipment located in close proximity. This IC converts 16-bit, 622-MHz SONET-framed data to 12 1.244-Gbit/sec serial data. The VSC7166 provides error detection and correction for a robust link in the presence of errors. To enhance system reliability, the device is capable of recovering data transmission in the case of a down channel. In addition, integrated simulation of error conditions enables the designer to verify robustness against such conditions during link operation.

Systems & Subsystems

Mini hub
The SC78 mini hub is a fiber-optic eight-port unmanaged hub that provides flexible node bypass capability for SCRAMNet SC78 networks. Individual nodes or subrings may be switched in or out of the system without disabling the entire network. Each of the product's fiber-optic ports can be attached to an individual SC78 network node, to another SC78 mini hub, or to a complete subring of SC78 nodes. For additional capacity, two hubs can be cascaded together to increase the number of available ports. The SC78 mini hub monitors all nodes for proper operation with a negligible effect on network latency. Large networks with multiple rings can be integrated since port-card signals are reclocked, ensuring the stability and integrity of the remaining network.
Systran Corp., Dayton, OH

SNMP-integrated chassis
The iMediaCenter platform features two-, eight-, and 18-slot chassis with a Simple-Network-Management-Protocol (SNMP) agent embedded directly on the chassis backplane. The innovation eliminates the need for separate management modules to be purchased, installed, and configured, according to the company. The SNMP agent enables network managers to monitor copper and fiber-link status information as well as chassis environmental statistics, including temperature and voltage level.

Multiservice switch router
A next-generation service-provider solution, the BXR-48000 is a 480-Gbit/sec switch router that advances the company's IP and multiservice infrastructure solutions. The router allows operators to decrease their annual operating costs by reducing overlay networks, migrating numerous legacy and emerging IP services onto one common network and optimizing bandwidth utilization for more efficient use of optical infrastructures. Because the BXR-48000 routes and switches numerous protocols across the backbone concurrently on a per-node or a per-port basis, Internet Protocol, frame relay, private-line, and ATM services can be engineered end-to-end over one scalable network.
Marconi, Pittsburgh

SAN gateway solution
SCSI over Internet Protocol (IP) capability has been added to the company's DiskLink SAN interconnect gateway. The new Gigabit Ethernet interface added to DiskLink as an alternative to existing ATM OC-3 and OC-12 wide-area interfaces, allows customers to build storage networks over IP backbone networks such as intranets and virtual private networks. SCSI over IP allows business-critical SAN applications, such as data replication and remote tape backup, to operate on existing IP networks, potentially saving the costs of wide-are connectivity. DiskLink is able to combine storage traffic from local Fibre Channel SANs and SCSI-based storage devices for transmission to remote sites over ATM or broadband IP networks.

Components Optical cordThis optical fan-out cord (FOC) is created without splicing, which provides users with loss-free routing. Because of its small size, loss from microbending is reduced. With a DAM 20 mm long and 3.2 mm in diameter, the FOC fits up to 192 port into a 19-in rack. The 0.9-mm FOC is wrapped in Kevlar, making it strong enough to endure increasing connector load, according to the company. Fiber ribbons are bound in a central package, which "fans out" where the plugs enter the unit. Both ribbon and cable fiber are incorporated, and standard connectors may be used to connect or disconnect the product. Singlemode and multimode fiber types can be customized to rack size and spacing.SENKO Advanced Components Inc., Southboro, MA

OC-48 framer technology
The Danube is a highly integrated OC-48 SONET/SDH framing-and-pointer processor device with on-chip features for next-generation optical-networking equipment. Danube provides an integrated solution, enabling customers to collapse multiple functions down to one chip, including aggregation, pointer processing, and grooming functions. The device enables the aggregation of 16 OC-3s, four OC-12s, or other logical combinations of OC-3 and OC-12 asynchronous interfaces into a larger OC-48 signal. The product can transparently remap the incoming OC-3 and OC-12 signals' transport overhead across time domains and into the outgoing higher rate signal.
