Technological Iteration and Upgrade | Yinxun Communications’ M10XE16H and ZMUX-10XE16H series SDH optical-electrical cross‑connect transmission equipment have been deployed in a project for a certain unit in Sichuan Province.
Release time:
2026-07-08
To meet the requirements of standardized SDH transmission network construction for government and enterprise private networks, and to comprehensively enhance equipment optical-port capacity expansion and cross-device interoperability, Guangzhou Yinxun Comm.Tech.Co..Ltd. (official website: www.gzyinxun.com) has completed a technological upgrade of its core optical transmission equipment, launching the new M10XE16H series and ZMUX-108X16H series of standardized optical transmission devices. Currently, these upgraded devices have undergone full-unit commissioning, network testing, and on-site deployment, successfully being implemented in a private network communication project at a certain institution in Sichuan, providing highly compatible and highly stable optoelectronic integrated transmission support for the establishment of local standardized optical transmission networks and the upgrading and renovation of legacy communication systems.
This equipment upgrade is an iterative development based on the company’s mature M10XE16G and ZMUX-10XE16G hardware platforms. Leveraging the robust hardware foundation of the existing devices, it introduces three core enhancements—FPGA‑based hardware optimization, crystal oscillator parameter tuning, and recompilation and reprogramming of the firmware—resulting in a new family of differentiated models with multiple specifications. The newly launched M10XE16H and ZMUX-10XE16H series are precisely tailored to accommodate optical‑port expansion, ring‑network deployments, and multi‑service transmission across varying scales. While maintaining a high degree of hardware versatility, these solutions significantly reduce both equipment procurement costs and subsequent operational maintenance burdens for government and enterprise private‑network projects.
In terms of model and specification configuration, this iteration has established a full‑range product portfolio that comprehensively covers 2‑port, 4‑port, and 8‑port optical interface requirements, with a standard configuration of 16 E1 interfaces. The models are further segmented to suit different network deployment scales:
I. New optical transmission equipment in the M10XE16H series
The M10XE16H series comprises three standardized model variants, namely:
M102E16H (2 optical ports + 16 E1 ports),
M104E16H (4 optical ports + 16 E1 ports),
M108E16H (8 optical channels + 16 E1 channels).
II. New Optical Transmission Equipment of the ZMUX-10XE16H Series
The ZMUX-10XE16H series comprises three standardized model variants, namely:
ZMUX-102E16H (2 optical ports + 16 E1 ports),
ZMUX-104E16H (4 optical channels + 16 E1 channels),
ZMUX-108E16H (8 optical channels + 16 E1 channels).
To ensure the stability and compatibility of upgraded equipment, the company employs a modular, universal design approach, enabling high‑level hardware reuse and precise, differentiated upgrades. The new‑generation motherboards for the M10XE16H and ZMUX‑10XE16H series, along with the E1 interface modules, are fully interchangeable; only the FPGA daughter boards are selectively configured to accommodate 2‑optic, 4‑optic, or 8‑optic setups. This significantly streamlines inventory management, equipment maintenance and replacement, and large‑scale capacity expansion efforts.
With respect to core hardware parameters, the technical team has carried out meticulous tuning and optimization: the M102E16H, M104E16H, ZMUX-102E16H, and ZMUX-104E16H models continue to employ industry‑standard, widely adopted FPGA daughter cards that are fully compatible with the M6536xG equipment; meanwhile, the high‑end 8‑port optical models, M108E16H and ZMUX-108E16H, are equipped with higher‑performance FPGA daughter cards to meet the data‑carrying requirements of large‑scale ring‑network deployments. In addition, the timing of the core FPGA daughter boards has been standardized and upgraded by replacing it with a standard reference clock source compliant with SDH specifications, thereby aligning the hardware at the lowest level with the SDH STM‑1 transmission‑clock standards. This effectively mitigates transmission faults such as optical‑path synchronization issues, bit errors, and transient link interruptions, ensuring temporal stability in long‑distance, multi‑node network configurations.
At the software‑level, standardized and unified iteration ensures seamless adaptation to the batch deployment and centralized operations‑and‑maintenance requirements of government and enterprise private networks. For the entire M10E16H and ZMUX‑10E16H product lines, the microcontroller bootloader and the main application firmware are common across all models, enabling batch project debugging, unified upgrades, and remote maintenance, thereby significantly boosting O&M efficiency. FPGA firmware is tiered and tailored to specific hardware configurations: the 2‑optic and 4‑optic variants—M102E16H, M104E16H, ZMUX‑102E16H, and ZMUX‑104E16H—share a single, unified FPGA firmware version; meanwhile, the high‑end 8‑optic models—M108E16H and ZMUX‑108E16H—deploy a dedicated, optimized firmware. After multiple rounds of full‑load stress testing, high‑ and low‑temperature aging tests, and field network validation, these devices demonstrate stable and reliable operation, fully meeting the 7×24‑hour continuous‑operation demands of private networks.
The new M10XE16H and ZMUX‑10XE16H series devices highlight their core advantages through standardized optical interfaces and fully compatible service ports. The “H” suffix indicates that the equipment supports the standard SDH STM‑1 optical transmission format, enabling seamless optical‑path interconnection with the company’s mainstream products—M6536xG, ZMUX‑6536xG, and ZMUX‑3038GE—thus perfectly accommodating new deployments in standardized SDH private‑network architectures. In addition, the devices feature non‑framed E1 interfaces, ensuring seamless E1‑service interoperability with the company’s entire legacy transmission portfolio. This capability supports mixed‑generation network deployments, reuse of existing links, and high‑level adaptation to scenarios such as upgrading aging PDH equipment, transforming government and enterprise private networks, and integrating new and legacy infrastructures. As a result, these solutions effectively address industry‑wide pain points associated with traditional private‑network upgrades, including protocol incompatibility, lack of device interoperability, and inefficient utilization of existing resources.
The successful deployment of this project at a Sichuan-based organization has thoroughly demonstrated the reliability and practicality of the M10XE16H and ZMUX‑10XE16H series SDH optical transmission equipment in scenarios such as standardized private network construction, flexible multi‑specification capacity expansion, and the compatibility‑based upgrade of legacy networks. This milestone further strengthens Yinxun Communications’ technical capabilities in government and enterprise private networks, as well as in the integration and modernization of new and existing systems. With years of deep expertise in optical communication transmission, Yinxun Communications has consistently addressed the pain points of industry‑specific private networks—particularly in civil aviation, power, government and enterprise sectors—by pursuing independent R&D and iterative innovation, continuously enhancing product compatibility, stability, and adaptability. The company delivers cost‑effective, highly available private‑network transmission solutions to industry customers.
Going forward, the company will remain focused on upgrading domestically developed communication transmission technologies, deeply addressing industry‑specific networking needs, and continuously expanding its core product portfolio—including optical transport, multi‑service access, and link protection switching. By delivering more specialized products, more mature solutions, and highly practical project services, we will provide robust technical and equipment support for nationwide customers’ communication network upgrades and new network‑deployment initiatives.
