Manufacturability with the Design 
Simplicity of Infinera's TROSA 
 
 In today's digital age, businesses require high-performance and cost-effective optical 
networks to meet the ever-increasing demand for bandwidth. Infinera's TROSA, or the 
"Transceiver Rotary-Servo Assembly," provides a simple yet powerful solution to this 
challenge. The TROSA design combines high-performance with ease of manufacturing, 
making it an ideal choice for businesses seeking to increase their network capacity while 
minimising costs. 
What is TROSA?  
TROSA, or Transceiver Rotary-Servo Assembly, is a new type of photonic integrated circuit 
(PIC) that enables high-performance optical networks with a simple and cost-effective 
design. The TROSA integrates several critical components required in optical networks, 
including lasers, detectors, modulators, and multiplexers, onto a single chip. This integration 
provides several benefits, including improved performance, reduced power consumption, 
and lower costs.  
High-Performance and Volume Manufacturability 
One of the primary advantages of TROSA is its high-performance and volume 
manufacturability. The TROSA's compact design allows for easy integration into optical 
modules, reducing the size and complexity of optical networks. Additionally, TROSA's design 
enables a high level of control over critical optical parameters, including wavelength, 
modulation, and polarisation. This level of control results in a high level of performance, 
enabling businesses to deliver the bandwidth needed for today's digital applications.  
 
Furthermore, the TROSA's volume manufacturability enables high-volume production of 
optical modules at a lower cost. The TROSA design simplifies the manufacturing process, 
reducing the number of components required to build optical modules. This simplification 
also reduces the potential for errors, resulting in a higher yield and lower production costs.  
Design Simplicity  
Another key advantage of TROSA is its design simplicity. The TROSA integrates several 
critical optical components onto a single chip, reducing the number of components required 
to build optical modules. This reduction in the number of components also simplifies the 
manufacturing process, reducing the potential for errors and improving the yield. 
Furthermore, the TROSA's design simplicity enables faster product development and 
testing, reducing the time to market for new optical modules.  
 
Applications of TROSA  
TROSA has a wide range of applications in the optical networking industry. One of the 
primary applications of TROSA is in optical transceivers, which are used to convert electrical 
signals into optical signals and vice versa. The TROSA's compact design enables the 
integration of multiple optical components onto a single chip, reducing the size and 
complexity of optical transceivers. This reduction in size also enables the deployment of 
optical transceivers in a wider range of applications, including mobile backhaul, data centre 
interconnects, and metro networks. 
 
Another application of TROSA is in optical amplifiers, which are used to amplify optical 
signals over long distances. The TROSA's design enables the integration of multiple optical 
components, including lasers and detectors, onto a single chip, improving the performance 
of optical amplifiers. This integration also simplifies the manufacturing process, reducing the 
cost of optical amplifiers.  
Conclusion  
Infinera's TROSA provides a simple yet powerful solution for high-performance and volume 
manufacturability in optical networks. The TROSA's design enables the integration of critical 
optical components onto a single chip, reducing the size and complexity of optical modules. 
Additionally, the TROSA's design simplicity enables faster product development and testing, 
reducing the time to market for new optical modules. The TROSA's applications in optical 
transceivers and optical amplifiers make it an ideal choice for businesses seeking to 
increase their network capacity while minimising costs.
