A transceiver boom is coming: Production lines optimization is the key to success

Maximum efficiency for optical transceiver makers will be the key to profitability as price competitiveness is expected on the client-side

Mobile communications have become so widespread that our lifestyles and changing beyond recognition. The 5G deployment is underway to prepare for the explosion of data traffic led by the evolution of services such as automated driving and big data. In this context, technological competition for upstream optical transceivers is intensifying due to digital coherent technology for higher speeds, greater capacity, and longer distances. In the meantime, the client-side optical transceivers, which are predominantly driven by demand within data centers are growing rapidly at a CAGR of 39.8% for shipment volume for the time period from 2018-25. Client-side optical transceivers are expected to be lower in cost, smaller in size, more integrated,


and lower in power consumption. Yet, with demand shifting from telecom-related applications to cloud service providers, the market structure is undergoing a major shift where the competition is fierce over the prices as well as alignment, assembly time reduction and space saving factors rather than the purely technological aspects.

A 70% improvement in alignment time, leading to maximum productivity 

As the SiPh market has begun to take off as a switch connection technology that enables lower cost, smaller integration and lower power consumption, the integration of modulators, waveguides, and photodetectors is progressing. Still, the hybrid type or existing discrete type, which requires the LD alignment mounting seems to remain as the mainstream for the time being. In order to reduce production costs, it’s important to have equipment with high production efficiency that can shorten the alignment time between the LDs and lenses (or optical waveguides), which require a long time for assembly. At the same time, manufacturers must be able to quickly set up a production system in response to the expansion of 5G infrastructure in the market. 

What is high-speed Peak Search Technology? 

Autocollimator technology, which leads the market share in the camera module and optical pickup markets, can be applied to the optical communication market to drastically reduce alignment time. The core of single-mode fiber (SMF) is small in size (5 to 10 μm in diameter) with a peak search adjustment tolerance of +/-0.1 to +/-1 μm. If the initial position for alignment is off by several tens to several hundreds of micrometers, it makes it difficult to easily detect the light. By using the lens optical axis detection technology developed by Suruga Seiki, we have succeeded in reducing the alignment time of optical communication devices and SMFs by instantly finding the light and leading it to the fiber core 70% faster than ever before. 
  • Quicker centering and assembly (70% less time than before) 
  • Space-saving equipment (1/3 of the equivalent production ratio achieved by shortening the production time) 
  • Fine drive for high coupling (2.5 times higher than conventional models due to technical innovations in the fine motion mechanism) 
  • Short delivery time for mass production (60% shorter than before based on the “misinterpretation time” strategy)
