Fiber Mall Announces High Performance 400G DR4 Silicon Photonics Optical Transceiver Solution

Fiber Mall has launched a high-performance 400G DR4 silicon photonics optical transceiver solution. The solution uses silicon photonics chip, combined with low-cost COB package, optimized high-frequency and power signal integrity design, effectively solving the silicon photonics optical transceiver packaging and photoelectric crosstalk problems, to achieve the industry’s leading performance of 400G DR4 silicon photonics optical transceiver solutions. The solution will be demonstrated site at CIOE in Shenzhen. For the company’s silicon photonics optical chip customers can open 400G module technology solutions, and provide optical engine OEM services.
The overall power consumption of 400G DR4 silicon photonics optical module based on this solution is lower than 8.5W, and it can support 10km single-mode optical fiber transmission. The TDECQ index of the four-channel eye diagram at the transmitter end using a silicon photonics optical chip is less than 1.5dB, the output optical power is more than 0.5dbm, and the receiver’s sensitivity (AOP) is higher than -9dbm. Technical indicators are at the industry-leading level.
