Fujitsu Laboratories Ltd. and Fujitsu Research and Development Center Co., Ltd. of China have been working on an optical technology that can achieve 100Gbps transmission speeds using commercial components intended for 10Gbps networking. The modulation technique they have adopted is Discrete Multi-Tone (DMT), which is widely used in DSL equipment but is not usually applied […]
A slew of optical transceiver announcements are expected in the coming days to coincide with the upcoming OFC/NFOEC conference and exhibition. The first CFP2 products – the CFP MSA’s 40G and 100G optical transceiver form factor that follows on from the CFP – are expected, as is further news of Cisco Systems’ own in-house CPAK […]
Swiss company Huber+Suhner AG says its new LC-XD fibre-optic connector will double the density of optical fibres per rack while also making it easier to manipulate fibres in central offices and data centres. Launched at the FTTH Conference 2013 in London, the new connector is designed to reduce space requirements, control costs and improve operational […]
Silicon photonics start-up Skorpios Technologies is getting close to delivering its first product: a full C-band tunable laser manufactured in a commercial semiconductor foundry. The new device is based on the Skorpios Template Assisted Bonding (STAB) process, which involves bonding a III-V crystalline layer to a CMOS wafer. The laser is fabricated in […]
Start-up Compass-EOS has announced availability of an IP core router based on an electronic chip with a terabit-plus optical interface. Having an optical interface directly to the silicon – which includes a merchant network processor – simplifies the system design and enables the router to incorporate such features as real output queuing, the […]
Fabless semiconductor company Netronome has demonstrated a flow processor chip implementing the OpenFlow protocol, an open standard implementation for software-defined networking (SDN). Operators and content service providers view SDN as a way to address changing traffic requirements in the data centre and the network. With SDN, operators can add their own intelligence to […]
EZchip Semiconductor has announced a class of network processor capable of performing traditional data plane processing as well as higher layer networking tasks. “It [the device family] is designed to provide processing for all the networking layers, from layer two all the way to layer seven,” said Amir Eyal, EZChip’s vice president of […]
ECI Telecom has announced a new family of packet transport platforms for the metro. The Native Packet Transport (NPT) platforms aims to reduce the cost of operating packet networks while supporting traditional TDM traffic. “Building carrier-grade packet transport is proving more costly than anticipated,” said Gil Epshtein, product market manager at ECI Telecom. […]
Cisco has announced new optical capabilities for its Cisco Routing System (CRS) family of core routers. This includes a programmable architecture that enables flexible provisioning of optical links carrying data rates of 100Gbps and above, as well as long-haul coherent 100G optical interfaces. The new technology, called nLight, provides information sharing between the […]
Avago Technologies has unveiled its first family of active optical cables. The company has also developed an optical module for use in the active optical cables (AOCs). The new Atlas 75x optical engine reduces the power consumption and the cost, enabling the AOC to better compete with traditional direct-attach copper cables. The AOC […]
In recent months Cisco Systems has been talking about its upcoming proprietary 100G optical module, dubbed CPAK. The development is expected to reduce the market opportunity for the CFP2 multi-source agreement (MSA) and has caused disquiet in the industry. “The CFP2 has been a bit slow – the MSA has taken longer than […]
The NG-PON2 standard has yet to be finalised, but that hasn’t stopped ZTE Corp. unveiling what it claims is the world’s first standards compliant time- and wavelength-division multiplex passive optical network (TWDM-PON) prototype at Broadband World Forum 2012 (BBWF) in Amsterdam. The Full Service Access Network (FSAN) group reached consensus about what the […]
Infinera is claiming an industry first with the software-enablement of 100G capacity increments. The company has added features to its DTN-X platform that shortens the time to add new capacity in the network from weeks, as is common today, to less than a day.Infinera has developed a DWDM line card that features its […]
MultiPhy has given early details of its 100Gbps coherent chip for metro networks, with samples expected in 2013. The company says it is seeing a market requirement for coherent technology’s deployment in the metro. “Everyone expects to see it [coherent metro] in the next two to three years,” said Avi Shabtai, CEO of […]
Oclaro and 3SPGroup, the former Alcatel Optronics, have established a new multi-source agreement (MSA) industry standard for pump laser packaging. The new MSA delivers a 70% reduction in size compared to legacy formats on the market. The current standard for pump laser packaging is based on a 14-pin format that has changed little […]
