Press Release Summary:
Standard 16-channel Dense Wavelength Division Multiplexer maintains 3 dB insertion loss over operating temperature of 0 to 60 deg C. Passive athermal performance avoids need for several watts of power to drive heaters or other temperature control devices, and for system monitoring and alarms to signal malfunction of temperature control devices.Original Press Release:
APA Optics Announces Limited Availability of Premium Low Loss DWDM Products Operating From 0° to 60° Without Active Thermal Control
Blaine, Minnesota: APA Optics has announced availability of premium low insertion loss (less than 3dB) models of its patented Dense Wavelength Division Multiplexing products.
Insertion loss for APA Optics' standard 16 channel DWDM products is 4dB, considered a high performance DWDM. By comparison, insertion loss for the new premium 16 channel model is less than 3dB, which is maintained at this level over an operating temperature range of 0° to +60° C, positioning APA Optics' device in the top tier of DWDM components available in the marketplace. Early customer feedback on these new low loss DWDM products has been very favorable. APA Optics intends to ramp production capacity in response to customer interest.
APA Optics' passive athermal performance helps reduce overall system cost for its customers because it avoids the need for several watts of power to drive heaters or other temperature control devices and for system monitoring and alarms to signal malfunction of temperature control devices required of high channel count components based on other technologies. "The combination of APA Optics' low insertion loss and passive athermal products supports a key goal of network system designers and users to reduce power consumption," reports Terry VanderWert, APA Optics general manager for fiber optic products.
VanderWert said that its low insertion loss models have been accomplished through improvements in design and assembly of the company's bulk diffraction grating based DWDM components. Improvements in packaging have contributed to demonstrated stability of the components during humidity aging and thermal aging.
