1. Market Background The global optical communication market is expanding rapidly driven by surging high-speed data transmission demand, especially in fast-growing emerging markets like India. With the large-scale rollout of 5G networks, fiber broadband upgrades and DWDM (Dense Wavelength Division Multiplexing) infrastructure construction, telecom operators and equipment integrators are in urgent need of high-performance, cost-effective passive optical components to enhance network capacity and signal stability. As core DWDM components, Athermal Arrayed Waveguide Grating (AAWG) modules play a pivotal role in optimizing fiber resource utilization and supporting large-capacity data transmission, fueling consistent growth in demand for high-channel-count standardized AAWG solutions. 2. Client & Application Scenario Our client is a well-established telecom equipment integrator in India, providing solutions for local telecom carriers and data center operators. The customer required a bulk order of optical multiplexing/demultiplexing modules to upgrade metro optical transmission networks and data center interconnection systems. They placed top priority on stable performance, on-time delivery and consistent product quality to support large-scale network deployment, avoid project delays and achieve seamless DWDM transmission link upgrades. 3. Our Solution & Key Technical Parameters We delivered a customized bulk order of 1500 units of 96-Channel AAWG Modules tailored to the client’s network architecture and deployment requirements. Designed for C-band DWDM applications, this athermal AWG module features ITU-T standard 50GHz channel spacing, fully passive operation (no external power or temperature control needed), low insertion loss, high channel isolation and superior long-term stability. Key specs include 96 optical channels, compact form factor, Telcordia GR-1209-CORE compliance and wide operating temperature range for harsh indoor/outdoor telecom environments. We also honored a strict 1.5-month delivery lead time, with full-process quality inspection to guarantee batch consistency. 4. Client Feedback After receiving and deploying the 96-Channel AAWG Modules, the Indian client shared highly positive feedback, confirming excellent in-field performance across all units. The modules delivered stable signal transmission, minimal signal attenuation and perfect compatibility with the client’s existing DWDM systems, fully meeting and exceeding performance expectations.

2~18CH CWDM MUX/DEMUX Module from GEZHI Photonics The key components in a WDM system are the optical wavelength multiplexer (MUX), and the de-multiplexer (DEMUX). In general, a CWDM (coarse WDM) MUX/DEMUX deals with small numbers of wavelengths, typically eight, but with large spans between wavelengths (spaced typically at around 20nm). A DWDM (dense WDM) MUX/DEMUX deals with narrower wavelength spans (as small as 0.8nm, 0.4nm or even 0.2nm), and can accommodate 40, 80, or even 160 wavelengths. The one kind of GEZHI Photonics LGX CWDM MUX/DEMUX modules are bi-directional passive optical multiplexers and de-multiplexers, allowing multiple optical signals at different wavelengths to pass through a single optical fiber strand. The second GEZHI Photonics ABS CWDM MUX/DEMUX modules are duplex fiber link bi-directional multiplexers and de-multiplexers, allowing multiple optical signals’ at different wavelengths to pass through duplex optical fiber. The last one kind is simplex directional CWDM MUX only or CWDM DEMUX only. The kind of mux and demux must be used with each other. CWDM MUX/DEMUX solution lets operators make full use of available fiber bandwidth in local loop and enterprise architectures. Our CWDM MUX/DEMUX modules split up to 18 channels (20 nm spaced) to a single fiber. The standard packages are ABS Plastic Box, 19″ Rack Mount Chassis CWDM Mux/Demux and LGX Metal Box Mux/Demux. No matter what kinds of connectors (such as FC, ST, SC, LC, etc.) are all available and we can also mix connectors on one device. CWDM MUX+DEMUX 8 Channels (Dual Fiber) Module GEZHI Photonics offers a wide range of WDM (Wavelength Division Multiplexing) optical networking products that allow transport of any mix of services from 2Mbps up to 100Gbe over dark fiber and WDM networks providing for the entire set of the most demanding CWDM and DWDM network infrastructure needs.
