KODENSHI KCX-T46-85DA

NEW PRODUCT
Single mode 850 VCSEL KCx-T46-85DA
Description
The KCx-T46-85DA consist of a single mode VCSEL of a high speed
and PIN Photodiode in the tilted window package. The power monitor
PD can be used with appropriate feedback control circuitry to set a
constant power level for each VCSEL. The VCSEL is actively aligned
with can sealing process. The VCSEL has a high coupling
efficiency, high slope efficiency, low operating current and low
tracking error and provides high optical performance.
