| HL1326CF/CN/SN/PF GaAlAs Laser Diodes Description The HL1326CF/CN/SN/PF are 1.3 m 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. Features * Wide operating temperature range: Topr = -40 to +85C * High output power: 3 mW (Pulse) 2 mW (CW) Low operating current: Iop (Pf = 2.0 mW) = 18 mA (Typ @TC = 25C) Iop (Pf = 2.0 mW) = 38 mA (Typ @TC = 85C) Fiber Specifications * * * * * * Mode field diameter: 9.5 1.0 m Cutoff wavelength: 1.10 to 1.27 m Outer diameter: 125 m Jacket diameter: 900 m Fiber minimum Bend Radius: 25mm Fiber length: More than 1000 mm 194 HL1326CF/CN/SN/PF 195 HL1326CF/CN/SN/PF Absolute Maximum Ratings (TC = 25C) Item Fiber optical output power Symbol Pf (Pulse) Pf (CW) LD reverse voltage PD reverse voltage PD forward current Operating temperature Storage temperature Note: VR (LD) VR (PD) I F (PD) Topr Tstg Rated Value 3* 2 2 15 1 -40 to +85 -40 to +85 1 Unit mW mW V V mA C C 1.
