1550nm PWDM with PD and WDM filter for CATV Receiver and Channel Monitoring

General DescriptionLW-TPD302M is based on a key technology that integrates thin film filter and mini-TO packaged photodiode. It is possible for a small single device to tap off optical signal and detect its power. Its body is electrically isolated from the two leads (electrodes), which prevents electrical shortage when assembled as an array. It drastically minimizes the general size of optical sub-systems that require high dense multiple tap-PD modules assembly.
The special technology used in the integration guarantees good optical characteristics and low deviation over a wide operating temperature range (-40 ~+85 )
With qualification of various and actual ESD threshold test methods, WPTS302M-SSNCN can improve your product quality while saving money and your company's reputation.
