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. Features - 850㎚ Wavelength Range - High Data Rate ≥ 2.5Gbps - High Reliability - Low Current and Voltage - Single mode - Other Configurations Available on Request Applications - High speed Data Communications - Gigabit Ethernet - Fiber Channel Characteristics Parameter Symbol Ith Min.
