Temperature-hardened Athermal AWGs for Extreme Temperature ApplicationsLOS ANGELES and SEOUL, South Korea, June 29, 2017 /PRNewswire/ -- POINTek, Inc., a global leader and provider of high performance athermal AWGs (AAWGs) and optical module packaging services, announced the increasing acceptance of temperature hardened Athermal AWGs that are used for DWDM deployment in the extreme temperature operating environment of -40°C ~ 85°C. Conventional athermal AWGs are designed to support a total of 60pm or larger wavelength drift, which amounts to compensating 0.5pm/°C shift in the operating temperature range of -40°C to 85°C. In POINTek's high-performing AAWG which is based on a new IP-pending optical packaging technology, the refined packaging technique allows only 20pm or less wavelength drift which is equivalent to 0.15pm/°C shift; hence, these high-performing AAWGs can sufficiently withstand the industrial temperature operational range of -40°C ~ 85°C. "POINTek's temperature-hardened AAWG is the result of continuing improvement of POINTek's athermalization technology and packaging process. We have been sharpening our packaging technique as the DWDM user community is getting ready for using a greater DWDM channel support beyond 50 GHz at the rate of 100G as well as an extreme temperature operating environment," according to Dr. TH Rhee, CEO of POINTek. "Our temperature-hardened AAWGs can support 25Ghz C-band DWDM. I label such AAWGs as Super AAWG as no commercial AAWG with this 20pm total, 0.15pm/°C shift performance is available on the markets today," Rhee adds. Since January 2004, POINTek has released its own athermalization IP-based AAWG products, starting from 16 CH AAWG in all type of spectral characteristics. Presently, POINTek manufactures and markets globally all custom type AAWGs in multiple channels (e.g., 40CH, 44CH, 48CH, 80CH, 88CH, and 96CH), spectrum (e.g., Gaussian, Semi-flat, and Flat-top), channel spacing (200GHz, 100GHz, 75GHz, and 50GH), band (C-band, L-band, dual C/L cyclic bands), optional features (e.g., internal or external monitoring TAP port, OSC port, etc.), package configuration (in brick or in chassis), and unique (e.g., comb filters) or special customized requirements (e.g., 1/2 MUX and 1/2DMX in one brick). "POINTek has been selling globally athermal AWG-based filters in different spectrum types and channels including WDM-PON enabling dual-band filters. We are selling not only temperature hardened AAWG for 1G~100 G data transport but also selling ultra-wide super-flat top AAWG capable of supporting up to 400G data transport on any DWDM channel" according to Dr. Donald Yu, CMO of POINTek, who runs global marketing operations in Los Angeles, California. Yu explains that POINTek's broad yet specialized optical packaging technology allows us to manufacture all types of customized AAWGs as POINTek's athermalization technology is good for optimizing temperature-induced wavelength shift up to 25GHz channel spacing. "As a niche vendor in providing Athermal AWG-based DWDM optical MUX/DMX solutions we have been closely following the market trends in DWDM system requirements, which show (a) increasing demand in temperature-hardened industrial temperature coverage AAWG and (b) anticipated demand for ultra-wide band super flat-top AAWG. The former is necessary for extreme temperature applications while the latter, for 400G data transport applications at the 5G telecom provisioning. Now, we have refined our optical packaging know-hows to the Super AAWG capability," Yu adds. POINTek management expressed their continuous commitments to their core AAWG products in the multitudes of the athermal AWG family products, and with refinement of optical packaging technique backed up by its discipline to the level of manufacturing and commercial production, the temperature hardened AAWG with the -40°C extended temperature application will be marketed aggressively through representatives in East Asia (Russia and Mongolia) and EU (Nordic countries in Sweden, Norway, and Finland) after its success in the North America (USA and Canada). About POINTek POINTek (Planar Optical Integration Technology) was launched in 2000 to promote PLC-based optical component and packaging service, and positioned as a niche market player in athermal AWG specialty products. POINTek has become a world leader in athermal AWG though patent-protected athermalization IPs and know-how's about process engineering in optical packaging for delivering high-performance and high-reliability DWDM products. POINTek's continuing R&D made it possible to produce and perfect the temperature-hardened AAWG and ultra-wide super flat-top passive AAWG MUX/DMX modules.
