With the increasing demand for higher bandwidth and better performance, the world’s leading Internet Exchange (IX) operators DE-CIX, LINX, AMS-IX & BCIX, will be introducing a new generation of optical transceivers, the 100G LR-1 (referred to as LR), to their platforms, starting in Frankfurt, London, Amsterdam, and Berlin.
While the existing 100G LR-4 uses four lasers, each carrying a signal of 25 Gbps, the new 100G LR technology uses only a single laser and uses pulse amplitude modulation (PAM4) to transmit data at 100 Gbps. The reduction in transceiver design complexity of the increasingly deployed 100G LR technology will result in power savings as well as better transceiver pricing. These advances not only provide advantages in the short to mid-term, but will also unlock new transceiver form factors that open up the potential for even greater performance and efficiency improvements in the future. The 100G LR technology is already available with a wide range of compatible routers from all major vendors and is compatible with current fiber technology. In order to satisfy today’s customer demand for 100G LR, DE-CIX, LINX, AMS-IX, and BCIX will provide support in the upcoming months.
Ruben van den Brink, CTO at AMS-IX says, “Offering 100G LR makes perfect sense, both for AMS-IX and for its customers. The lab tests proved that the new optics can be used for all the switches that are currently deployed in our Amsterdam PoPs. I appreciate the fact that we were able to collaborate with our partners in pushing this new standard. When Internet Exchanges join efforts, customers benefit, so I hope many more exchanges will start offering 100G LR soon.”
“With the new 100G LR technology, we are paving the way for the next generation of transceiver technology that will dominate the market for years to come. The future design of our DE-CIX interconnection platform will not only bring better programmability and higher scalability, commercial flexibility, and wider geographical reach, it will also make interconnection even easier for our customers through simplified technical processes,” says Dr. Thomas King, Chief Technology Officer at DE-CIX.
Richard Petrie, CTO at LINX stated, “For LINX, we will be enabling our London locations first after approving the solution in our lab. We will roll out as demand grows and as we see that LINX members need support in the shift to the improved optics. This will realise both benefits in cost and power for us and the LINX member base.”
“After testing 100G LR and other 100G single-lambda standards in our lab, we have already introduced this new technology into our production network. By doing so we have built a very cost-efficient interconnection between data centers on the same campus. Offering the same benefits to our peers is just the next logical step,” says André Grüneberg, CTO at BCIX.
