China has achieved a significant breakthrough in optical communication technology, with the world's first three-band ultra-low-loss multi-core optical fiber cable line officially entering service.

The world's first ultra-low-loss multi-core optical fiber cable line supporting the S+C+L triple-band (short band + conventional communication band + long band) has recently been officially completed and commissioned in Qingdao, Shandong. This new optical fiber line surpasses the transmission capacity limits of traditional fibers, marking a new commercialization phase for China's space-division multiplexing fiber and multi-band integration technology, and offering an innovative technical solution for computing interconnectivity and ultra-high-bandwidth transmission in the intelligent era. The triple-band refers to the S-band (short band), C-band (conventional communication band), and L-band (long band) of optical communication signals, representing a core upgrade direction for AI computing power, all-optical networks, and 5G-A/6G.

High-speed optical modules ramp up production; optical filters may become the new bottleneck component in photonic devices

① The Z-BLOCK component forms a wavelength separation module by sequentially bonding filters with different center wavelengths onto a single glass substrate, enabling spectral splitting and combining at the transceiver ends of optical modules. ② Guosheng Securities noted that demand elasticity for optical filters has significantly increased with the ramp-up of 800G/1.6T high-speed optical modules.
