With the deployment of the fifth generation of mobile networks (5G). 25 and 100 Gb/s directly modulated lasers and modules will become the mainstream optical transmitters. A directly modulated InGaAlAs/InP distributed Bragg reflector (DBR) laser is fabricated by butt-joint technology. A 25 Gb/s data transmission over a single-mode fiber of up to 10 km is demonstrated. https://parisnaturalfoodes.shop/product-category/virgin-coconut-oil/
