June, 10 2023
The optical transceivers are used for transmitting and receiving optical signals in high-capacity data centers. Generally, the data centers feature a hierarchy type of Ethernet network. These networks can be copper-based, fiber-based, or hybrid (copper-fiber). In the modern network, upgrading all devices to fiber-based components may not be convenient. Optical transceivers are used in certain cases to convert an electric signal into an optical signal. These signals are further transferred through fiber optic cables. The transceivers consist of pairs of transmitters and receivers which play an important role in the electro-optical and reverse conversion of signals.
Since in high-capacity data centers, multiple copper-fiber connections are required, multiple numbers of optical transceivers are used. Each optical transceiver is exposed to a high volume of data packets and therefore, the need for upgradation and performance enhancement of optical transceivers is a constant requirement.
Network engineers for high-capacity data centers often face challenges for optical transceivers due to the increasing demand for performance efficiency.
Let’s Discuss Key Trends in the Optical Transceiver Market –
The demand for higher data rates in modern applications is driving the need for more advanced optical transceivers
Higher data rates required for applications such as cloud computing, video streaming, and high-performance computing are set to provide significant opportunities to manufacturers.
The deployment of 5G networks is expected to drive the demand for optical transceivers, as these networks require high-speed, reliable, and low-latency data transmission.
The adoption of fiber optic technology across several industries, such as telecommunications, healthcare, and transportation is expected to drive the demand for optical transceivers since they are essential components of fiber optic networks.
The demand for energy-efficient solutions is increasing in several industries, including data centers and telecommunications, which are driving the development of optical transceivers that consume less power and generate less heat.
Challenges for Optical Transceivers in Data Center Networks
The challenges for optical transceivers are generally related to the design and deployment of the transceivers in the network. The challenges are discussed below.
* Device Compatibility: Often the optical transceivers are integrated with laser diodes and signal decoders. The operation of the transceiver takes place between the transmitter and receiver based on the optical pulses generated by laser diodes and electric signals decoded by the signal decoders. This phenomenon is compatible with fiber optic cables and devices. However, in many data centers, the networking devices are copper-based and therefore are not compatible with fiber optics transmission. In certain cases, the optical transceivers should be integrated strategically. This is where the major challenge for optical transceivers is seen.
* Network Design and Layout: Data center networks consist of multiple layers like core, spine (distribution layer), leaf (access layer), etc. The transceivers are spread across these layers. Often the switches in these layers are inundated with data traffic and therefore the receiver units of transceivers may suffer delayed delivery of data packets.
* Sustainability: The sustainability of optical transceivers is a challenge due to the complexity and high-temperature generation in data center networks. The optical transceivers are sensitive to dust particles, moisture, and high temperatures, so must be designed to resist these parameters. Therefore, a lack of sustainability may cause abrupt network failure.
* Transmission Capabilities: As the optical transceivers only transmit signals in the formal optical pulses. The capability of this optical transmission depends on factors like transmission bandwidth, mode of transmission, etc. If these capabilities of an optical transceiver are not sufficient for the working of a data center, then it becomes challenging to enhance efficiency.
Despite all the challenges, optical transceivers are used in the data center networks by deploying smart, calculated solutions to overcome these challenges. Owing to the same, the demand for optical transceivers remains high. The next section introduces you to some forecasted optical transceiver trends.
Optical Transceiver Trends in Data Center Networks
The following optical transceiver trends have been reported and forecasted by industry experts.
Important operational Parameters of Optical Transceivers to Consider when choosing them.
The fiber optic transceivers are essential for electrical to optical data conversion and vice-versa. When buying them, you need to consider several factors such as the type of data converted, data speeds, distance to be covered, equipment used for plugging these transceivers, etc. In addition, these transceivers can transmit different wavelengths, and signal attenuation is less in long wavelengths. So, if you consider fiber optical transceivers like SFP transceivers for your high-speed network, ensure to invest in MSA-compliant transceivers, which are compatible with most switches and router platforms. Many transceiver manufacturers also provide switches and routers, which helps reduce your incompatibility issues.
Flexibility is the name of the game in a digital-first world, which is transforming data centers as we’ve known them for decades. Depending on the latest industry analyst report or news cycle, some experts assert the future of data centers is hyperscale while others believe processing power will be delivered locally, in the cloud, and at the network’s edge. Regardless of technologies, topologies, and terminologies, here’s one thing everyone agrees on next-generation data centers must be agile, adaptable, distributed, efficient and intelligent.
According to Gartner, spending on global data center infrastructure was expected to reach $200 billion by the end of 2020. This represents a 6% increase after spotty spending in 2020, as many enterprises put infrastructure investments on hold while relying more on public cloud providers to address pandemic-related business shifts and disruptions.
Cloud adoption, which was growing steadily before COVID-19, gained major momentum during the pandemic. According to Flexera’s “2021: State of the Cloud Report,” more than 92% of the 750 enterprises surveyed currently have a multi-cloud strategy while 90% expect their cloud use to exceed plans due to the pandemic, an increasingly remote workforce and a surge in videoconferencing. The report also reinforces the evolution of public and private cloud adoption, with 43% of those polled leveraging a hybrid strategy to meet business needs.
As companies move from monolithic data center designs to distributed and disaggregated architectures, myriad new challenges emerge. Enterprises of all shapes and sizes are seeking ways to ease transitions to new heterogeneous environments. The goal: Choose from a menu of computing, storage, and networking options to best meet business needs while only paying for what is used.
