HL1327CF/CN/SN/PF are 1.3µm InGaAsP Fabry-Perot laser diodes with a multi-quantum well (MQW) structure. They are suitable as light sources in short and medium range fiberoptic communication systems. Laser output is delivered from the coaxial package through an attached single mode fiber. A built-in photodiode provides monitor current output.
The HL1327CF/CN/SN/PF series are 1.3 µm InGaAsP Fabry‑Perot laser diodes with a multi‑quantum‑well structure, intended for short‑ and medium‑range fiber‑optic communication. Light is emitted from a coaxial package into an attached single‑mode fiber, and a built‑in photodiode provides monitor current.
