Key Product Review

Commercial 100GHz & 50GHz DWDM TFF and DWDM Wavelength Division Devices

Yongding Optoelectronics 100GHz and 50GHz DWDM TFF are the core chips in DWDM transmission networks and are widely used in OTN backbone, metropolitan area and 5G fronthaul networks, and the next generation 50G-PON. Yongding Optoelectronics pioneered its own core technology in China, invested heavily in multiple coating machines and auxiliary production and testing equipment, and adopted advanced ion-assisted deposition IAD technology to achieve ultra-smooth polishing and extremely small wavelength temperature drift, reaching the international first-class level. Simultaneous supply of various packages including 100GHz and 50GHz DWDM devices and modules.

athermal arrayed waveguide grating Athermal AWG

The athermal array waveguide grating (AAWG) introduced by Yongding Optoelectronics is based on planar optical waveguide PLC technology, independent core technology, from AWG chip design flow sheet, sealing test, to module design, coupling, sealing test, to achieve the whole process of core technology localization. At present, it has been mass produced at 100GHz, 150GHz and 50GHz on a single chip for multiplexing/demultiplexing of dense wavelength division multiplexing system (DWDM). The product has the characteristics of low loss, high channel isolation, convenient use, long-term stability and reliability, compact size (Nano,Mini optional), etc., and has been widely used in 5G fronthaul and optical transmission networks worldwide.

TFF Thin Film Filters for Biomedical and Automotive Radar Applications

Yongding Optoelectronics introduced TFF film filters, including biomedical and automotive radar market applications. 400 ~ 850nm high transmittance and high reverse filter for biomedical applications, used for laser emission or reception, spectral separation and other applications, and EM 540nm/20 filter. 850nm, 905nm, 1550nm bandpass filters for automotive radar applications. The product has the characteristics of low loss, high channel isolation, commercial reliability, flexible customization and so on.

100G QSFP28 ER1 Optical Module

Yongding Guangtong's 100G ER1 optical module is based on 100G Ethernet rate and is packaged in QSFP28. The HOST electrical interface side supports 4*25.78 Gb/s rate. The laser adopts EML PAM4 modulation mode of 53GBaud Rate with TEC and supports four wavelengths of 1295.56/1300.05/1304.58 and 1309.14 in the LAN-WDM band. The detector adopts APD scheme with 53G baud rate. Support up to 40km single-mode fiber (G.652) transmission distance. The module comes with 100G RS FEC mode, 24-hour traffic frame service hangs up without frame loss, and adopts unique heat dissipation design to meet the power consumption of less than 4.0W in the commercial temperature range.

5G communication photoelectric composite cable

Yongding 5G communication photoelectric composite cable in the structure of the transmission copper wire and optical fiber combined into one, can choose the pipeline directly buried, overhead and other construction methods. Its specific advantages are mainly manifested in the following points: First, the cable has small outer diameter, light weight, and good structural optimization; Second, the cost is relatively low, the construction is simple, and the construction cost is low; Third, it has good lateral pressure resistance and outstanding bending performance, and has strong applicability; Fourth, one-time laying can provide multiple cable transmission performance such as communication and power at the same time, and has strong applicability and scalability with equipment; five, can provide relatively large broadband access; Six, can simply solve the problem of equipment power supply in the process of network construction; Seven, if you don't need one of the functions, you can do alternative reservation function to avoid secondary construction costs; Eight, can be prefabricated according to user requirements.

Focused programme review

Based on self-made core coating technology and advanced industrial device technology, Yongding Optoelectronics has introduced a series of PON wavelength division products with low insertion loss, high isolation and high reliability, which can decompose and reuse various PON networks such as EPON, GPON, NGPON, 50G PON, etc. to meet different customized requirements.

With regard to 50G PON, there are widespread technical difficulties in the industry at present: the upstream wavelength interval between 50G-PON and G-PON is only 2nm, and it is very difficult to realize wavelength division multiplexing with 30dB isolation. Yongding has been the first to achieve technological breakthroughs, with reliable technical solutions and support for mass production.

In this exhibition, Yongding further demonstrated the industrial layout from "optical chip-device-module-system integration" and "rod fiber cable. Dream with light, build light with core. Yongding will continue to uphold the enterprise spirit of "carrying letters with sincerity, never ending", take innovation as the driving force, continuously improve the core competitiveness of enterprises, and contribute to the development of the industry.
