The ML9XX45 series are InGaAsP laser diodes that provide stable, single transverse mode oscillation with an emission wavelength of 1550nm and a standard continuous light output of 5mW. The ML9XX45 is a hermetically sealed device with a photodiode for optical output monitoring. This is suitable for applications such as FTTH (Fiber to the Home) systems.
The ML9xx45 series are InGaAsP Fabry‑Perot laser diodes offering typical emission wavelengths of 1550 nm or 1520 nm, low threshold current, and stable single‑mode operation. They are hermetically sealed and include a photo‑ball lens cap for optical output monitoring, making them suitable for FTTH (Fiber to the Home) systems.
Key specifications include a continuous‑wave output power of about 6 mW, operating voltage around 1.5 V, reverse voltage ratings of 2 V (laser) and 20 V (photodiode), and an operating temperature range from –40 °C to +85 °C. Outline drawings for the various package types (ML920J45S, ML925B45F, etc.) are provided.
