Today, as the digitalization process continues to accelerate, although IP networks have become the mainstream direction of communication development, in many key industry application scenarios, traditional TDM networks still play an irreplaceable role with their high stability and strong real-time performance. Especially in the fields of power dispatching, rail transit, petrochemicals, public security private networks, etc., PDH (Plesiochronous Digital Hierarchy, quasi-synchronous digital system) optical terminal still plays an important role as an efficient and reliable transmission equipment. Shandong Oriental Communication Technology Co., Ltd. has been deeply involved in the optical communication industry for many years. With its strong R&D capabilities and manufacturing advantages, it has launched a series of high-performance and cost-effective PDH optical terminal products, which continue to enable global customers' private network communication system upgrades and stable operation.
PDH optical terminal is an optical fiber communication device based on the E1 interface, which supports long-distance transmission of multiple E1 channels through a single optical fiber. It has the characteristics of simple structure, stable transmission, and strong anti-interference ability. Compared with IP bearer mode, PDH equipment has lower requirements for network bandwidth and more flexible deployment, especially suitable for high-reliability scenarios such as remote site communication, industrial control, and emergency dispatch. Shandong Oriental Communication's PDH optical transceivers are widely used in many key projects at home and abroad. The products are exported to more than 30 countries and regions such as Germany, India, Saudi Arabia, and South America, winning a good reputation and wide recognition.
High-performance PDH optical transceivers to meet various communication needs
Shandong Oriental Communication's PDH series products cover multiple models from 1E1, 2E1, 4E1 to 16E1, 32E1, etc., supporting single-fiber bidirectional and dual-fiber unidirectional transmission modes. Some models integrate multiple service interfaces such as Ethernet, voice, and serial ports to meet customers' diverse application needs. The equipment adopts a fully digital design, supports automatic compensation of optical power, real-time monitoring of transmission status, power-off protection and other functions to ensure high stability and reliability of data transmission.
In addition, the company's products generally support industrial-grade working environments, have earthquake-resistant, lightning-proof, and moisture-proof designs, and can operate stably in a wide temperature range of -40℃ to +85℃, suitable for complex and harsh environments such as outdoor base stations, substations, and traffic tunnels. Some models are also equipped with dual power supply redundancy, DIN rail installation and SNMP remote management functions, which facilitates rapid deployment and remote maintenance on site.
Rich application scenarios, adaptable to multi-industry private network communication systems
Typical application scenarios of PDH optical transceivers include but are not limited to:
Power system dispatching communication:Transmit the voice and SCADA data of each substation back to the main control center through PDH equipment to achieve high-reliability transmission and delay guarantee;
Railway/subway signal communication:E1 channel remote connection between signal machines and train control equipment to ensure the real-time transmission of traffic instructions;
Petrochemical monitoring system:Realize remote data collection and dispatch information transmission of oil field sites, gas stations, etc.;
Public security and emergency communication network:As a voice dispatch and control signal transmission channel, build a stable and reliable secure private network;
Enterprise remote office/factory area connection:Provide E1 dedicated line long-distance interconnection for group companies to reduce operating costs.
Shandong Oriental Communication tailors PDH optical transceiver solutions for different customers by combining standardized products with customized services. Whether customers have special requirements for the number of interfaces, power supply methods or shell structure, the company can provide flexible customization, including rack-mounted, wall-mounted, portable and other forms, as well as AC220V, DC48V, dual power supply redundancy and other power supply methods, to fully meet the deployment requirements of various application scenarios.
Technology and quality are equally important to win the trust of global customers
Shandong Oriental Communications strictly implements the ISO9001 quality management system in the design and manufacturing process of PDH optical terminals. All products undergo 100% aging test, optical power test, bit error rate test, electrical port signal integrity test and other processes before leaving the factory to ensure the long-term stable operation of the products. The company's products comply with many international certification standards such as CE, FCC, RoHS, etc., and can meet the compliance requirements of the export market for electromagnetic compatibility, safety and environmental protection.
Against the background of increasingly fierce competition in the global communication equipment market, Shandong Oriental Communications has always adhered to the development concept of "quality-oriented, service-oriented, win-win cooperation", and is committed to providing customers with communication equipment solutions with superior performance, reasonable structure and flexible deployment. At present, the company has established long-term cooperative relationships with many communication operators, system integrators, and engineering contractors, providing one-stop support from project consulting, technology selection, solution design to after-sales service, truly realizing the product value of "delivery is application".
Looking to the future, building a more intelligent and integrated transmission system
Although the communication industry is accelerating towards IP and optical networking, PDH optical terminals will still play an important role in terminal access, edge transmission and special industry private networks. Shandong Oriental Communications will continue to promote the technical upgrade and management function expansion of PDH products, and actively integrate into the communication needs of emerging fields such as industrial automation, smart grid, and urban security. At the same time, the company will also accelerate the pace of product internationalization, expand overseas market layout, and create a globally competitive optical communication brand.
Through continuous innovation and service optimization, Shandong Oriental Communications Technology Co., Ltd. will use high-quality PDH optical terminals and a full range of optical communication equipment to help customers build a more stable, efficient and secure communication network infrastructure, and continue to empower global information interconnection and industrial digital transformation.
