Explore our highly integrated, industrial-grade 1x9 optical modules supporting 155M and 1.25G transmission speeds over single-mode and multi-mode networks.
While modern hyperscale data centers transition rapidly toward pluggable SFP, SFP+, and high-density QSFP architectures, the 1x9 optical transceiver remains an indispensable foundation for mission-critical industrial telecommunications and ruggedized field applications. Characterized by its single-row, 9-pin design, the 1x9 form factor provides superior mechanical stability and secure solder-down connectivity that modern hot-swappable form factors cannot match.
Unlike SFP modules that rely on delicate sliding contact pads, 1x9 transceivers are directly soldered to the printed circuit board (PCB), offering absolute immunity to intense physical vibration, mechanical shock, and long-term contact oxidization.
Our 1x9 transceivers utilize TTL (Transistor-Transistor Logic) or PECL (Emitter-Coupled Logic) signaling interfaces, facilitating direct interface with legacy processing units. This legacy-to-modern bridge prevents full system re-designs in critical public utility, marine, and aviation transport networks, saving millions in infrastructural CapEx.
Ensures zero frame loss in railway signalling, aircraft control systems, and machinery instrumentation where motion is constant.
Withstands standard industrial operating temperature ranges of -40°C to +85°C. Sealed housings prevent entry of airborne dust and humidity.
Perfect for critical infrastructure projects planned with a 15-to-25-year operational lifecycle, eliminating the risk of frequent component end-of-life cycles.
Equip-Link Intelligent Equipment (Shenzhen) Co., Ltd. delivers certified, high-yield optical communication components from the heart of Asia's advanced hardware manufacturing hub.
Founded in 2017, Equip-Link Intelligent Equipment (Shenzhen) Co., Ltd. is a leading manufacturer and supplier of high-performance optical transceivers and fiber optic communication solutions. We specialize in the design, development, production, and global distribution of optical modules for data centers, telecommunications networks, enterprise networking, cloud computing, and AI infrastructure applications.
Our modern manufacturing facility covers an area of 380 square meters and is equipped with advanced production and testing equipment to ensure consistent quality and reliable performance. With an annual export revenue exceeding USD 18 million, Equip-Link has established long-term partnerships with customers in more than 50 countries and regions worldwide.
With 9 years of export experience and 14 years of industry expertise, our team understands the evolving demands of global communication networks and delivers products that meet international standards for performance, compatibility, and reliability.
Quality is at the core of everything we do. We implement a comprehensive quality management system supported by incoming material inspection, in-process quality control, and final product testing. Every product undergoes rigorous testing using advanced optical and network performance analyzers before shipment.
Every step of our production workflow is rigorously monitored by our dedicated QA division, staffed by 36 experienced inspectors who ensure strict adherence to international standard operating procedures (SOP).
Deploying robust 1x9 transceivers across critical industrial sectors to ensure uninterrupted flow of digital assets under hostile conditions.
Substations deploy high-voltage equipment generating massive Electromagnetic Interference (EMI). 1x9 optical modules decouple communication lines from electromagnetic fields, ensuring stable command links between switches and SCADA masters via IEC 61850 protocol standards.
In harsh automation facilities, manufacturing machinery requires deterministic communication over Ethernet. Using soldered 1x9 transceivers prevents structural physical disconnects and data frame latency variations (jitter) caused by physical machine vibrations.
Urban metro railway systems rely on CBTC (Communication-Based Train Control) systems. Dual SC and BiDi 1x9 transceivers form the core backbone of trackside networking cabinets, supporting transmission lengths up to 80km to reliably span outer station boundaries.

Equip-Link utilizes premium optoelectronic components including high-efficiency Distributed Feedback (DFB) lasers, Fabry-Perot (FP) laser transmitters, and high-sensitivity Avalanche Photodiode (APD) receivers or PIN photodetectors. Together with proprietary onboard driver ICs, our modules maintain precise transmission optical power limits while limiting optical back-reflection, which dramatically lowers the Bit Error Rate (BER) across the fiber link lifecycle.
Our dedicated R&D division, comprising 68 professional engineers, performs rigorous testing for compatibility with legacy systems and devices from Cisco, TE, Avago, and many others. We successfully launched 126 new products in the past year, proving our deep commitment to updating and expanding our portfolio. We support custom coding configurations, tailoring the electrical pins, and configuring custom firmware to match the signaling requirements of legacy machinery controllers.
