What is an APD detector?
Dec 03 , 2025
The full name of an APD detector is Avalanche Photodiode detector. It is a high-sensitivity photoelectric detection device whose core function is to convert weak optical signals into measurable electrical signals. It is widely used in fields such as optical communication, laser ranging, and low-light imaging. Compared with ordinary photodiodes, its biggest advantage lies in its signal am...

Energy Efficiency vs. Transmission Distance: A Comprehensive Analysis of Core Features of 100G SFP-DD (DR1/FR1/LR1)
Mar 10 , 2026
With the ever-growing demand for data center interconnection, single-wavelength optical transceivers compliant with the 100G Lambda MSA standard have become the mainstream choice due to their advantages of high density, low power consumption and low cost. Based on our company's three SFP56-DD packaged optical transceivers – the 100G SFP-DD DR1 (RSD-100G-DR1), 100G SFP-DD FR1 (RSD-100G-FR1) a...

Central Equipment Room – Pole-Mounted Multi-Site CWDM/DWDM Cascading Network Solution
Jun 15 , 2026
Scheme Overview This scheme is designed for the chain cascading transmission scenario from the central equipment room to multiple pole-mounted sites. Leveraging CWDM/DWDM wavelength division multiplexing technology, it enables multi-site and multi-service signal transmission over a single fiber or a pair of fibers through the coordinated deployment of passive multiplexer/demultiplexer devic...
