HYC Showcases Hybrid Series Product at ECOC 2020 Virtual Event

The European Optical Fiber Communication Exhibition ECOC is the largest optical fiber communication exhibition in Europe, which is held in EU countries every year. The event was originally scheduled to take place in Belgium in September, but due to the impact of the epidemic, it was rescheduled to take place online on December 7-9. HYC also participated in this virtual exhibition with the latest products and solutions. At the virtual exposition, visitors will have the opportunity to explore HYC’s high-density cabling solutions, micro-optic solutions, 5G Open-WDM solutions and more.

In recent years, the integrated optical passive devices are smaller in size and more mature in technology, occupying a considerable part of the market share. As one of the key devices of optical communication, erbium-doped fiber amplifier (EDFA) has become the technical focus of competition among many manufacturers due to its integration, miniaturization, multi-function and low cost.  HYC has launched a series of customized small N in 1 integrated high-end devices that can be applied to ultra-small EDFAs to help realize the above-mentioned competitive advantages of EDFAs. The above competitive advantages of EDFA can be realized by integrating optical isolator, wavelength division multiplexing (WDM) devices, optical circulator and test access port (TAP) splitter into a hybrid device.

In addition to the above-mentioned Hybrid components, HYC also demonstrated full-band/dual-window/multimode/polarization-maintaining couplers, fiber optic circulators, MPO/MT-FA, AWG CWDM4 and other micro-optic solutions.

At this exhibition, HYC also highlighted the CEx wavelength coexistence WDM module used in the "Trip-play" network. The CEx WDM module is a transitional product in the evolution of PON technology.  At present, the main PON technologies can be divided into three types: TDM-PON, WDM-PON and OFDM-PON. The original proposal of CEx wavelength coexistence is mainly to allow G/EPON to realize system sharing with NG-PON1 and NG-PON2, so as to achieve a smooth upgrade and save costs.

For 400G transmission applications, HYC is also actively exploring new solutions, and has launched a series of AAWG products such as 50GHz 96CH AAWG and 75GHz 64CH AAWG. Arrayed waveguide gratings (AWGs) are key components of DWDM (Dense Wavelength Division Multiplexing Systems) networks that are rapidly developing. The AWG can obtain a large number of wavelengths and channel numbers, realize multiplexing and de-multiplexing of tens to hundreds of wavelengths, and can flexibly form multifunctional devices and modules with other optical devices. High stability and excellent cost performance are also one of the reasons why AWG has become the technology of choice for DWDM. Based on the array waveguide grating technology, it does not require additional power supply or temperature control, and is a pure passive module. The application of AAWG can greatly improve the propagation efficiency of optical fiber networks.

ECOC's online exhibition will be open until January 15. Customers from all over the world are welcome to visit HYC's online virtual booth to explore new technologies and directions in the optical communications industry.
