Edge router for video
Targeting the service provider network edge, the Aggregation Services Router 9000 Series (ASR 9000) is designed to deliver massive scale, non–stop video experience, and a reduced carbon footprint. The series will include 10– and 6–slot versions and is designed to eventually accommodate 400 gigabits per slot. Along with the existing CRS–1, XR–1200, and 7600 Series routers, the new platform enables the company to extend its IP–over–DWDM strategy from the core to the edge. The larger version of the router is engineered to provide up to 6.4 Tbps of total capacity. The router design is optimized for video services support and features the company's Advanced Video Services Module, which is designed to enable terabytes of streaming capacity for edge aggregation applications. It also supports content caching, ad insertion, fast channel change, and error correction.

The 7300 Metro Ethernet Switching series is targeted at operators looking to build scalable networks to deliver Carrier Ethernet services for business Ethernet access, carrier infrastructure projects like DSLAM aggregation, and wireless backhaul applications. The first in the series, the 7345 Ethernet Aggregation Switch, provides aggregation of up to forty–eight 10/100/1000–Mbps optical or electrical interfaces into 10–Gigabit Ethernet uplinks in a 2RU shelf configuration. It is temperature–hardened for deployment in uncontrolled environments and provides flexible support for redundant port interfaces, redundant power supply, and redundant control plane processors to satisfy a range of operators' deployment needs. In addition, its Ethernet feature set supports both traditional switched Ethernet applications and emerging connection–oriented applications.
Unlike traditional ROADM systems, the CoreBridge3200 does not use a wavelength–selective switch (WSS) or wavelength blocker; instead, it relies on a conventional arrayed waveguide grating (AWG) and coupler combination to achieve ROADM functionality. The approach provides capex savings versus the traditional approach, the company asserts. In addition to the full set of ROADM features such as non–blocking switching, remote reconfiguring, and automatic one–click path searching, the CoreBridge3200 provides interfaces from 100 Mbps to 40 Gbps, enabling a range of services such as Fast Ethernet, Gigabit Ethernet, 10–Gigabit Ethernet, SONET, etc. The maximum capacity of transport is 1.28 Tbps (32 wavelengths Ã� 40 Gbps), and the maximum reach without 3R is up to 560 km over conventional fiber.

TOSAs for 40GBase–LR4
A series of new 10–Gbps transmit optical subassemblies (TOSAs) operate on the ITU–T CWDM grid at 1271, 1291, 1311, and 1331 nm and meet the emerging 40–Gigabit Ethernet requirements for 40GBase–LR4, as standardized by the IEEE 802.3ba Task Force in support of 10–km transmission over singlemode fiber. Based on a buried hetero–structure DFB laser chip design, the TOSAs incorporate an integrated InGaAsP monitor photodiode and are packaged in a TO–header with receptacle, compatible with the 10–Gbps XMD MSA, for uncooled use over an operating temperature range of –5ÂºC to +75ÂºC and transmission rates of up to 10.7 Gbps. The new TOSA series, including the TX1270, TX1290, TX1310, and TX1330, will be available in full production quantities in 2Q09.

The GN2406 quad 10–Gbps clock and data recovery (CDR) device is aimed at optical modules, backplanes, line cards, and active copper cable assemblies. Used to restore and clean digital signals at extremely high data rates, the new CDR provides a retimed interface for InfiniBand quad data rate (QDR), 40–Gigabit Ethernet (XLAUI), and 100–Gigabit Ethernet (CAUI) applications. The GN2406 also features output de–emphasis, which is a form of transmit equalization that compensates for the loss of the transmission medium. Using the GN2406, backplane trace losses of up to 25 dB can be compensated, thus enabling backplane link lengths greater than 1 m. Each channel in the GN2406 independently locks to data rates from 9.95 to 11.3 Gbps. To support legacy data rates, half–rate (5 Gbps) and quarter–rate (2.5 Gbps) operation is also supported.
Combining low–cost bidirectional optics packaging with high–speed optical device technology, this new fully SFF–8431 compliant SFP+ module transmits and receives on a single fiber, improving the efficiency of telecommunication networks by reducing fiber cost and simplifying fiber management. The optical specifications are modeled after the 10–km 10GBase–LR interface, but use two different wavelengths in the 1300–nm window for upstream and downstream transmission. Based on the manufacturer's existing 10–Gbps SFP+ platform, the bidirectional modules have a power dissipation of <1 W, which is consistent with high–density applications. The 10–Gbps bi–directional transceivers will also be offered in the XFP form factor.

Quadwire is a parallel active optical cable that provides a 40–Gbps aggregate link via four 10–Gbps full–duplex channels. Based on the industry–standard QSFP form factor, the cable uses fiber–optic technology to transmit parallel high–speed data over ribbon multimode fiber. It is based on the company's vertical–cavity surface–emitting laser (VCSEL) array technology. The cable's small diameter supports large port count architectures, enabling simpler installations and fiber management.

The OPTICOM FRME–U fiber rack–mount enclosures provide a flexible system for managing fiber terminations, connections, and patching in all types of telecommunications room and work area applications. They combine simple installation and high patch–field density with integral cable management features to ensure end–to–end signal integrity for increased network reliability. FRME–U enclosures are available in 1–RU and 2–RU versions and are compatible with the company's OPTICOM Fiber Adapter Panel based field termination or field splicing installations for greater system versatility.
The FIBERLIGN Center–Lock Aerial Slack (CLAS) storage bracket for in–span cable storage features a “Center–Lock Hinge” that allows the bracket halves to swing open, rest onto the main cable, and close into storage position (a butterfly motion), thus eliminating excess attachment components and metal fasteners. Heavy–duty cable straps simplify attachment to the main cable and simultaneously lock the bracket while securing slack cable. The FIBERLIGN CLAS Storage bracket provides in–span storage for ADSS cables up to 1 inch (25 mm) in diameter. Expansion tabs allow 20–inch (508 mm) maximum loop diameter storage and multi–cable storage for butt splice applications. The CLAS bracket halves can be separated at the center–lock hinge for efficient storage.

40G/43G tester for lab settings
The STT 40G is a 40/43–Gbps test system designed to verify the performance of new, high–bandwidth SONET/SDH and OTN networks and is the newest member of the company's existing STT product family. A multipurpose tester, the STT 40G enables users to test a range of Ethernet traffic streams up to 10GbE, SONET/SDH, xWDM, and ROADM technologies in a single platform to reduce capex. The optional 10/10.7–Gbps drop feature gives technicians the ability to drop test signals to lower–rate instruments and perform complementary tests. The company says this feature is especially valuable in lab settings where technicians often need to map lower–rate signals coming from a network element, simulator, or analyzer to 40/43–Gbps links. The STT 40 should also see use in central offices and in the field.
