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 […]
A new project being funded under the European Union’s Seventh Framework Programme (FP7) aims to develop a new field-installable fibre-optic connector with performance comparable to factory pre-connectorized cables. The aim is to speed up the roll out of fibre-to-the-home (FTTH) networks across Europe. Going under the moniker “Versatile Easy installable Connector implementing new […]
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 […]
ZTE claims to have set a new world record for 400G high-speed optical transmission based on single-carrier DWDM. The Chinese vendor presented a paper about its work at ECOC in Amsterdam. In the experiment, ZTE successfully transmitted 40 channels, each carrying 400Gbps, over 2800km of standard singlemode fibre arranged in 35 spans, with […]
Team members of MODE-GAP, an European collaborative R&D project that is part of the EU 7th Framework Programme on next-generation internet infrastructure, presented no fewer than three post-deadline papers at the ECOC 2012 conference in Amsterdam. Now half-way through its four year programme, the MODE-GAP project is exploring ways to increase the capacity […]
NeoPhotonics has announced a multiport mode coupling receiver (MCR) transceiver that enables operators to boost the efficiency of their fibre-to-the-home (FTTH) networks by connecting up to four times as many homes to each existing OLT slot in a central office. One common approach to reduce the cost of FTTH installation is to keep […]
Teraxion has adopted silicon photonics technology for its latest compact 40- and 100-Gbps coherent receivers. The Canadian optical component company, better known for its fibre Bragg gratings and tunable dispersion compensation products, has spent the last three years developing expertise in silicon photonics. At the recent ECOC exhibition it announced its first products based […]
JDSU will soon bring to market its tunable SFP+ pluggable module, and has already delivered to equipment makers samples of the compact tunable laser design. The company, which demonstrated the tunable SFP+ at the recent ECOC exhibition, has not given a date when it will start production. “It won’t be long,” said Brandon Collings, […]
