The enterprise and data center markets are going through what some experts call a “once in a decade transition.” Driven by the insatiable demand for ever-increasing bandwidth, these industries are rapidly moving from 40G to 100G networks while also upgrading from shorter-reach multi-mode fiber to longer-reach, single-mode fiber mesh architectures.
This is good news for the optical components companies and network equipment manufacturers because the anticipated volumes should represent a very healthy industry for many years to come, with demand likely outstripping supply at some point.
However, the question that remains unanswered is whether we can continue this rapid pace of innovation? Here we are set to deploy 100G in the second half of 2016, and the industry is already talking about 400G. The amount of money that will need to be spent in R&D to enable 400G is going to be substantial and it’s not clear the industry is set up in a way that will naturally allow that to happen. Component and module manufacturers are already investing tens of millions of dollars in manufacturing capital to support data center volumes, and when this does not get amortized, it has a negative financial impact on these companies.
This is further compounded by the fact that the industry wants these innovations faster than ever, placing enormous pressure on the entire distribution chain to unrealistically shorten time-to-market schedules for new data rate equipment. As hyperscale data center operators and cloud providers own both ends of the network, there has been a rapid proliferation in the number of optical interfaces and connection choices, as they can use non-standard interfaces. At 10G, there were two and at 100Gb, this has increased to eight. From a component supplier, this makes leveraging economies of scale across operations much more difficult.
To better understand this issue, let’s take a look at where the innovation in the data center is now being driven from and what needs to happen to maintain that innovation so we can continue achieving higher data rates in the future.
New Architectures Need New Technologies
Getting to higher speeds such as 100G, 200G or 400G require new, more complex network architectures in the data center. Core optics are essential elements to transition to these higher speed networks, and they are also critical for enabling the move from multi-mode networks to single-mode networks. Optical transceivers are no longer optional features in the data center. Rather, they are absolutely critical components for delivering increased faceplate density, higher bandwidth, lower power consumption and longer reach.
Just take a look at today’s mega data centers. These can house over 100,000 servers, all of which are inter-linked to function as a flexible, parallel computation engine. To realize efficient and powerful computing, interconnects between servers and switches in these data centers must operate continuously at high speeds (40G-100G); with negligible latency (nanosecond delays); low power (<35mW/G); and over long distances (10m-10km). The only way to meet these requirements is through optical fiber interconnects. When 100G is deployed, it will be driven by the availability of core optical components and modules – from the Jericho and Tomahawk ICs now available to the QSFP28 and CFP2-ACO transceivers needed to achieve the density that supports the I/O speeds on those chips.
Challenges Ahead
With 100G in sight, the industry still wants better, faster, cheaper and lower power – and they want it quicker in terms of faster time-to-market. This is going to place enormous pressure on the core optical components industry, which has been undergoing significant changes itself. Below are the key challenges and issues that the industry needs to address to keep moving forward:
A Path to Good Heath
Core optics are going to be critical components in the data center and enterprise for decades to come. As a result, it is going to be extremely important for optical component companies to stay ahead of the curve with smart R&D investments and business models that not only deliver the required high speed optical innovations, but long-term, profitable growth. To this end, the entire industry must evolve so the wealth is better allocated across the entire supply chain. This means changing relationships from optical component companies being solely viewed as suppliers to instead being joint partners. By working closely together to create new technologies, scalable operations and profitable business models we can raise all boats. The result will bring to market some of the most revolutionary solutions that deliver the speed, performance and value that data centers of the future need while enabling our industry to thrive and prosper.
