Nearly 190,000 visitors attended the exhibition, and more than 3,000 upstream and downstream enterprises from the global optoelectronic industry chain gathered here, focusing on displaying materials, equipment, technology and complete sets of solutions, sharing and exchanging new technologies and new modes in the industry.

Etern brought its optical passive components, chips and assemblies, transceivers, fiber optic cables and other series of products, as well as 50G PON three-generation coexistence solutions to the exhibition. Etern team actively answered technical, product and other related questions for visiting customers and friends, shared insights on new technologies, products and solutions, and gradually established new contacts and partnerships in enthusiastic communication.

Key Products Review

Commercial 100GHz & 50GHz DWDM TFF and DWDM WDM Assembly

Etern Optoelectronics 100GHz & 50GHz DWDM TFF is the core chip in dense wavelength division multiplexing (DWDM) transmission network, which is widely used in OTN backbone, metro and 5G front-haul network, and the next-generation 50G-PON.Etern Optoelectronics is the first one who creates its own core technology in China, and invests heavily in multiple coating machines and auxiliary production and testing equipment. With the advanced ion-assisted deposition (IAD) technology, Etern Optoelectronics achieves ultra-smooth polishing and extremely small wavelength temperature drift, reaching the international first-class level, and can synchronously supply a variety of packages such as 100GHz and 50GHz DWDM assembly and modules.

Athermal AWG

Athermal Arrayed Waveguide Grating (AAWG) launched by Etern Optoelectronics is based on planar optical waveguide PLC technology, independent core technology, from AWG chip design, wafer flow, sealing and testing, to the module design, coupling, sealing and testing, to achieve the whole process of localization of core technology. At present, we have mass production of 100GHz, 150GHz, single chip 50GHz for Dense Wavelength Division Multiplexing (DWDM) multiplexing/demultiplexing system, which is characterized by low loss, high channel isolation, easy to use, long term stability and reliability, and compact size (Nano,Mini optional), and it has been widely used in global 5G front-haul and optical transmission networks.

Thin Film Filters(TFF ) for Biomedical and Automotive Radar Applications

Etern Optoelectronics has launched TFF for biomedical and automotive radar applications. The 400~850nm high transmission and high reflection filters for biomedical applications are used for laser transmission or reception, spectral and color separation applications, and EM 540nm/20 filters. 850nm, 905nm, 1550nm bandpass filters for automotive radar applications. The product features low loss, high channel isolation, commercial reliability, and flexible customization.

100G QSFP28 ER1 Optical Transceiver

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

5G communication optoelectronic composite cable

Etern 5G communication optoelectronic composite cable combines power transmission copper wire and optical fiber into one in its structure, and it can choose construction methods such as direct burial in pipeline and overhead. Its specific advantages are mainly manifested in the following points:

small cable outer diameter, light weight, and good structural optimization;

• relatively low cost, easy construction, and low construction cost;
• good lateral pressure resistance and outstanding bending performance, and strong applicability;
• one laying can simultaneously provide communication and power and other cable transmission performance, and the applicability of the equipment is strong, and the scalability is strong;
• it can provide relatively Huge broadband access;
• it can be a simple solution to the process of network construction, equipment power supply problems;
• if you don't need one of the functions, you can do the alternative reserved functions, to avoid the secondary construction spending;
• it can be prefabricated into the end in accordance with user requirements.

Based on self-manufactured core coating technology and advanced industry component process, Etern optoelectronics has launched a series of low insertion loss, high isolation and high reliability PON WDM products, which can multiplex and demultiplex various PON networks such as EPON, GPON, NGPON, 50G PON, etc., and can meet different customized demands.

Regarding 50G PON, the technical difficulty that exists more widely in the industry at present: the uplink wavelength interval between 50G-PON and G-PON is only 2nm, and it is very difficult to realize WDM with 30dB isolation. Etern has taken the lead in realizing technical breakthroughs, possessing reliable technical solutions and supporting batch production.

In this exhibition, Etern further demonstrated its industrial layout from "Chip - Assembly - Module - System Integration" and "Optical Rod & Fiber & Cable". Carrying dreams with light, building light with chip. Etern will continue to uphold the enterprise spirit of "Stay in Integrity, Pursue the Limitless", take innovation as the driving force, continuously improve the core competitiveness of enterprises, and contribute to the development of the industry.
