April 16, 2025, Shenzhen, China. – The SVIAZ 2025 International Communications Exhibition will take place from April 22nd to 25th at the Expocentre Fairgrounds in Moscow. GIGALIGHT will participate in the event, presenting innovative optical interconnect products and solutions at Booth 22F40, Pavilion 2 Hall 2. Global customers and partners are invited to visit for in-depth discussions.
At the exhibition, GIGALIGHT will highlight six key technological solutions and demonstrate multiple new product demos, showcasing its expertise in data centers, AI computing networks, 5G communications, DWDM systems, and liquid cooling interconnects.

Featured Solutions and Product Demos:
Incoherent Color ZR+ 100G DWDM Solution
New Product Demo: 100G QSFP28 PSM DWDM4 (C-BAND)
The GIGALIGHT four-carrier Color ZR+ C-BAND 100G QSFP28 PSM DWDM4 optical transceiver features an MPO-12 interface (12-core) paired with an external wavelength division multiplexer/demultiplexer. Powered by DCM dispersion compensation and EDFA amplification, it supports transmission distances of at least 80km. The transmitter employs 4x25G C-band 100GHz DWDM EML lasers, while the receiver uses PIN detectors, offering 48CH wavelengths. With total power consumption below 5W, it delivers 1200G bandwidth over dual-fiber or 400G over single-fiber. This transceiver plugs directly into 100G QSFP28 switch ports, eliminating the need for traditional DWDM electrical layer equipment. GIGALIGHT also provides a one-stop solution with its proprietary intelligent 1U optical layer device, integrating DWDM EDFA, AAWG, and tunable TDM or fixed DCM for rapid deployment.

Incoherent Color X O-BAND DWDM Solution
New Product Demo: 100G QSFP28 DWDM1 (O-BAND)
The GIGALIGHT Color X O-BAND series 100G QSFP28 DWDM1 silicon photonic transceiver utilizes a 200GHz O-BAND DWDM Grid and single-wave 100G PAM4 silicon photonic modulation technology. Equipped with a Duplex LC interface, it offers 16 selectable wavelengths, achieving 1600G total bandwidth over dual-fiber single-mode fiber for DCI interconnects. Paired with an SOA optical amplifier, it supports 30km transmission (10km without SOA) and eliminates the need for dispersion compensation DCM modules. With power consumption below 3.5W, this solution outperforms coherent DWDM in cost, latency, power efficiency, and ease of deployment.
