Optical Transceiver Fiber Coupling

The datacom market is dominated by the explosive growth in cloud data centers mostly belonging to internet giants such as Amazon, Microsoft and Google. This growth is required to meet consumer expectations of on-demand, high quality and real-time access to content via a multitude of applications across a wide range of devices such as smartphones, tablets, laptops, PCs and smart televisions. Data centers now represent >65% of the overall telecom and datacom market for optical transceivers.

The combined requirements from data center operators for ever higher bandwidths, reduced footprints and lower costs, demands new ways to address the classic challenges and constraints inherent in transceiver fiber coupling solutions.

Optoscribe’s unique 3D glass based photonic integrated circuit platform is ideally suited for creating custom transceiver fiber coupling and attaching solutions designed to specifically address the challenges of individual transceiver architectures and configurations. These include the following components:

  • Waveguides with full 3D flexibility (Single mode fiber) (Multimode fiber)
  • Mirrors for 90o light turn
  • "V" grooves for precise passive alignment of fiber
  • Precise fiducial markers 

Challenges with Optical Transceiver Assembly

It is widely accepted that the assembly of optics inside transceiver packages remains largely at best a semi-manual task not ideally suited to high volume product ramping.

The demands being exerted on transceiver manufacturers call for imaginative monolithic, solid state solutions to the fiber coupling challenge to facilitate high volume manufacturing while maintaining consistent, high quality finished product.

Transceivers, particularly those based on single mode fiber, are difficult and therefore expensive to assemble and package, dominating the overall cost of the final module. This is precisely what Optoscribe’s glass-based 3D photonic integrated circuit platform is targeted at reducing assembly costs in optical transceiver manufacturing.
