As Japan accelerates its Digital Transformation (DX), the demand for high-density networking in metropolitan areas like Tokyo (Minato-ku, Koto-ku) and Osaka has reached unprecedented levels. The 2xN stacked configuration is critical for maximizing port density in space-constrained Japanese data centers.
With the rollout of 5G by NTT Docomo, KDDI, and SoftBank, edge computing nodes require SFP28 (25G) and QSFP+ (40G/100G) 2xN stacked cages that can handle high thermal loads while maintaining signal integrity in compact outdoor enclosures.
The Japanese market mandates strict adherence to VCCI Class B EMI standards. Our 2xN stacked ports feature enhanced 360-degree EMI shielding gaskets and optimized press-fit pins to ensure zero interference in sensitive industrial IoT environments.
The evolution of interconnect systems from 10G to 112G PAM4 has fundamentally changed the requirements for 2xN stacked port designs. In the Japanese telecommunications sector, where reliability is the non-negotiable benchmark, Deltavox Optics provides a technical roadmap that bridges the gap between legacy systems and future-ready infrastructure.
Deltavox Optics Technologies Co., Ltd. is a professional optical communication solutions provider specializing in the design, manufacturing, and global supply of high-performance optical transceivers, fiber optic modules, and networking components. Established in 2016, the company operates from a modern manufacturing facility with a building area of 18,500㎡ and has developed strong expertise in optical communication technologies.
With an annual export revenue of approximately US$18 million, Deltavox Optics has accumulated 7 years of export experience and 12 years of industry experience, serving customers across telecom, data center, enterprise networking, and industrial communication sectors worldwide.
The company maintains strict quality management systems and performs comprehensive quality inspections, including automated optical testing, transmission performance verification, temperature cycling tests, aging tests, compatibility testing, and reliability evaluations. A professional quality control team of 56 inspectors ensures every product meets international standards and customer requirements.
2024-2025: Transitioning from SFP+ to zSFP+ and zQSFP+. Integration of multi-stage light pipes for real-time status monitoring in dark-room data centers.
2026+: Adoption of Co-packaged Optics (CPO) compatible cages. High-performance EMI shielding using liquid metal gaskets for hyper-scale cloud providers in Japan.
Q: Are your 2xN stacked ports compliant with Japan's VCCI regulations?
A: Yes, all our SFP+ and QSFP+ stacked cages are designed with advanced EMI shielding gaskets and are tested to meet VCCI Class B requirements, ensuring they are suitable for both industrial and commercial environments in Japan.
Q: Do you offer local technical support in Japan?
A: We partner with major distributors in the Kanto and Kansai regions to provide rapid localized support, including customized FAE (Field Application Engineering) services for large-scale infrastructure projects.
Q: Can you provide customized firmware for optical module compatibility?
A: Absolutely. Our R&D team of 126 engineers specializes in firmware customization to ensure 100% compatibility with Japanese OEM equipment from NEC, Fujitsu, and Mitsubishi Electric.
Q: What is the typical lead time for a bulk order to Yokohama port?
A: For standard 2xN stacked port configurations, our typical lead time is 2-3 weeks, with efficient sea or air freight options directly to major Japanese ports.
