Finisar introduces 25G optics for high-speed data centres
Finisar has released two new products for 25Gb/s data centre applications including an SFP28 eSR (extended short reach) optical transceiver enabling 300m links over existing OM3 multimode fibre, and 25G SFPwire, an active optical cable (AOC) with embedded diagnostics technology that provides visual indicators of data centre connectivity. Built using in-house optics and ICs, the SFP28 eSR transceiver targets 25 Gigabit Ethernet (GbE) data centre applications. The new optical module extends links from 70m to 300m over existing OM3 multimode fibre, and interoperates with current 25 GbE SFP28 SR and QSFP28 SR4 modules. By using this product with their existing fibre infrastructure, customers can increase network bandwidth by 2.5x compared to 10 GbE networks. The 25G SFPwire AOC is the ideal solution for intra- and inter-rack high-speed data centre interconnections, Finisar claims. Designed for ease-of-use, the new AOCs are lighter, more flexible and lower in power consumption than comparable direct-attached copper cables. Finisar’s laser and IC technology deliver high signal integrity and reliable performance for error-free 25G connectivity. This allows customers the option to by-pass the host forward-error correction (FEC), to create non- standard, low-latency connections. The 25G SFPwire AOC also includes embedded Connectivity Diagnostics technology to provide data centre operators with real-time performance monitoring, through both a host- software interface and visual indicators on the AOC pull-tabs. The only technology of its kind in the industry, Connectivity Diagnostics provides critical information used for troubleshooting, link performance monitoring and port-connectivity mapping. For instance, the pull-tab lights up when one end of the cable isn’t plugged in correctly, allowing data centre operators to locate and fix the problem far more quickly. The 25G SFP28 eSR will be available in the first quarter of 2017; with the 25G SFPwire AOCs available late 2016.

Nistica expands WSS line-up for next- generation architectures
Nistica has announced two new wavelength- selective switch (WSS) modules designed for next-generation high-capacity route-and-select architectures. The first product is an L-band twin WSS module optimised for transmission in the long- wavelength band for operators that are interested in using the additional spectrum. The second offering is a twin MxN WSS that allows system integrators

FOC releases comprehensive industry glossary
Fiber Optic Center (FOC), a supplier of all equipment needed for the automated production of fibre-optic cable assemblies, has added a comprehensive industry glossary to its website. Containing more than 3,600 entries and more than 2,000 abbreviations, the FOC glossary includes military specifications for connectors in addition to general terms and definitions. The resource covers fibre, cable, wire, optics, assembly, connectors, electrical, data communications and testing terms, as well as the FOC ancillary expert areas of polymers, chemicals, lapping film, adhesives and epoxies.
MACOM introduces 64GBd quad- channel modulator driver
Semiconductor supplier M/A-COM Technology Solutions has introduced the MAOM-006428, a 64GBd quad-channel linear Mach-Zehnder modulator driver. This device will support data rates of 400Gb/s and beyond on a single wavelength for long-haul coherent transmission. By increasing the data rate on a single wavelength, operators can increase capacity and reduce the overall cost-per-bit. Metro networks can use higher-order modulation formats at 32GBd to achieve this, but these higher-order modulation formats such as 32- and 64-QAM have very limited
OFS unveils TeraWave SCUBA Ocean optical fibre
OFS used the OFC exhibition in Anaheim, California, to introduce TeraWave SCUBA Ocean Fibre, which is optimised for 100Gb/s optical transmission and above in submarine cable systems. TeraWave SCUBA can support transoceanic distances of up to 12,000km, where extreme distances between shore end terminals place extreme demands on the optical signal-to- noise ratio for DWDM transmission. Compared to earlier generations of submarine optical fibres, TeraWave SCUBA reduces the performance limitations introduced by fibre

The goal is to make it easier to both reference and understand common industry terms and definitions, as well as encourage a dialogue with the industry. FOC plans to expand the resource with more standards, processes, edits, and additions.

reach due to signal-to-noise requirements. Long- haul networks therefore require the use of higher baud rates up to 64G to achieve data rates of 400G on a single wavelength. MACOM’s MAOM-006428 modulator driver
features surface mount inputs and G3PO outputs to mate with the next-generation high-bandwidth modulator, which is currently being standardised by the Optical Internetworking Forum (OIF). The device has linear performance to support higher order modulation formats with low power consumption, and a compact form factor of 275mm2

nonlinearities and amplifier noise. The fibre has large effective area of 153μm2 to reduce nonlinearities, and ultra-low attenuation of 0.155 dB/km at 1550nm to reduce signal loss. These properties allow higher signal powers to be launched into the span and reduce amplifier noise. Applications without repeaters, such as coastal festoons and deep-water crossings, can also take advantage of the large effective area of TeraWave SCUBA Ocean Fiber, which permits higher power handling capacity without additional distortion, meaning more channels at higher speeds over longer distances before amplification is required.

to offer multi-directional connectivity in mesh networks.
The L-band WSS is offered in twin 1x9 and twin 1x20 port options, while the twin MxN WSS is software programmable to configure M inputs and N outputs, where M + N = 21. Available as a stand alone WSS module, or as part of one of Nistica’s high-density single-slot reconfigurable optical add drop multiplexer (ROADM) line card designs, the new arrivals are currently being integrated
into products by Tier-1 network equipment manufacturers as they develop the first high- capacity, multi-directional, flexible-grid network solutions.
Both new products have the same form factor as Nistica’s current switches and can be driven via similar software interfaces, thereby streamlining the process of integration into new line cards and reducing development cycle times for customers.
