Multi-mode transceivers are less expensive than single-mode transceivers and exactly the reverse for the fibers. What Data Centers are 2 km or 1. Most electronics are made with silicon using complementary metal oxide semiconductor CMOS fabrication techniques. The economies of scale inherent to batch processing cut the price way down. Optoelectronic components represent the biggest cost centers of the optical network. That said, not all capital outlays are equal. Deploying 40GEthernet was as easy as multiplying that by four for a 4x10G architecture. One thing to note: And do they have any difference? Although speed is important in the data-center space, the economics and special constraints make cost and complexity more important than speed. Single-mode fiber is used by the telecom industry and ordered in hundreds of thousands of miles per year — and so it is inexpensive. The best use case is at reaches less than meters. The approach also improves performance, simplifies assembly, reduces footprint, and decreases heat generation. Making the jump to GEthernet was altogether trickier. Each channel has its own fibers and is separated throughout the link. While G PSM4s are fairly new to the market, as the popularity climbs and volume manufacturing efficiencies kick in, the PSM4 has a chance at challenging the G SR4 multi-mode transceiver in similar market prices when the transceiver and fiber link costs are added up. For each channel in the system, the CWDM architectures need a transmitter, a multiplexer, a demultiplexer, a detector, etc. Part of the reason that 10G Ethernet has such a strong installed base of the data center is because the standard clock speed of the electronics used in optical networking was 10G. In summary, the optical communications industry continues to support the data-center market with a number of choices to enable users to develop the best network for their solution. Silicon Photonics — Solves the Manufacturing Problems Silicon Photonics does away with most of these problems and integrates the optical components and waveguides into a silicon wafer — the same basic technology used to build CMOS semiconductor electronic chips. The link length can be up to m. With an optical multiplexer and de-multiplexer, we only need to use a duplex single-mode fiber to connect two G CWDM4 optical transceivers. Still, research work is underway in the laboratory to solve these issues for a near-term implementation. Summary The PSM4 transceiver is the lowest-cost single-mode transceiver available today for use in next-generation data centers as it employs the low-cost and long reach features of single-mode fiber. Meanwhile, data-center operators and service providers need high speed operation now.

Multi-mode transceivers are less expensive than single-mode transceivers and exactly the reverse for the fibers. In , chips with 25GHz clock speeds hit the market. Instead of transmitting over multiple channels on a single fiber, it uses four parallel fibers lanes operating in each direction, with each lane carrying a 25G optical transmission. That means cost savings are a function of distance. The 9-um single-mode fiber is very hard to build and align transceiver components with and requires very expensive alignment equipment. Active Optical Cables AOCs are two transceivers with the fibers permanently attached inside and not removable. There is a tipping point past which PSM4 networks can become more expensive than their CWDM counterparts as a result of cable costs alone see figure 1. Scaling by a factor of 10 without increasing the clock speed significantly increased the number of components involved, which raised cost, complexity, and integration time. NeoPhotonics sells InP lasers that work with silicon photonics chips to support G deployments in the data centers. For example, CWDM architecture requires multiple optical components 4xlasers, 4xlenses, 4xmux, 4xfilters, 4xdetectors, electronics each assembled by semi-automated packaging techniques to align and bond onto a common substrate or package to form an optoelectronic sub-assembly. It uses eight times as much fiber over each link as the CWDM solutions, however. It operates over distances of up to meters. This is similar to needing a very powerful flash light to shine through a dense forest of twigs, branches and leaves in the way even though the distance is relatively short.

  1. Although fiber cost is important, it is a one-time investment for data-center operators. More components also meant more points of failure.

  2. Although speed is important in the data-center space, the economics and special constraints make cost and complexity more important than speed. So what are they?

  3. Single-mode fiber is used by the telecom industry and ordered in hundreds of thousands of miles per year — and so it is inexpensive.

  4. Active Optical Cables AOCs are two transceivers with the fibers permanently attached inside and not removable.
