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.

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 –5ºC to +75ºC 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.

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.

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.
