CWDM boosts G.653 fiber capacity by up to 16x with low cost, fast deployment, and seamless compatibility for modern optical networks.

Impact of form factor on performance   The performance of a 400GZR module depends heavily on its form factor, including power consumption, cooling requirements, and compatibility with current infrastructure. Typically, this is achieved by using standard form factors such as QSFP-DD (quad small form-factor pluggable double density) or OSFP (octal small form-factor pluggable), which are… Continue reading What are the key factors to consider when selecting a 400G ZR module?

CWDM equipment powers 5G networks with affordable, seamless base station-to-core connectivity. Discover its role in optical communication

Optical transmission mechanism   Information is transmitted through optical transmission via light waves in optical fibers. The main idea is to transmit and modulate optical signals to carry data. It first generates a laser-driven optical signal and then connects it into an optical fiber. As it moves along the fiber, it undergoes total internal reflection,… Continue reading How does a 400G ZR optical transceiver work?

High-speed optical transmission equipment is 400G transceivers, which allow data centers to send and receive data at speeds of 400 gigabits per second. These systems utilize PAM4 (quad-level pulse amplitude modulation) as one of the advanced modulation formats or technologies to double the existing data capacity on optical fiber without the need for additional cables.… Continue reading What are 400G ZR transceivers?

Computing power is growing at a rate of 10 times per year. Under Moore’s Law, the computing power of a single chip can no longer bear this speed alone. Therefore, a more efficient interconnection structure and protocol mechanism need to be introduced at the system design level. The existing network architecture faces bottlenecks. Scale-up and… Continue reading AI computing demand is exploding, how should optical communications respond?
