| MITSUBISHI (OPTICAL DEVICES) FU-427SLD-F1 1.3 mm LD MODULE WITH SINGLEMODE FIBER PIGTAIL DESCRIPTION Mod ule type FU-427SLD-F1 has been developed for coupling a sin glemode optical fib er and a 1.3 mm wavelength InGaAsP LD (Laser diode). FU-427SLD-F1 is suitable to light source for highspeed long haul digital optical communicatio n systems and measuring instruments. FEATURES High-speed response Emission wavelength is in 1.3 mm band Low threshold current (7mA typ.) With photodiode for optical output monitor MQW* active layer FSBH** structure fabricated by all MOCVD process *Multiple quantum well **Facet selective-growth buried heterostructure APPLICATION Trunk Line,FitL ABSOLUTE MAXIMUM RATINGS Parameter Laser diode (Tc=25 C) Symbol Conditions CW Rating 3 Unit mW Optical output Pf power from fib er end Reverse voltage Vrl Vrd Ifd Tc Tstg Reverse voltage Forward current - 2 15 2 -20~+75 -40~+85 V V mA C C Photodiode for monitoring Operating case temperature Storage temperature MITSUBISHI (OPTICAL DEVICES) FU-427SLD-F1 1.3 mm LD MODULE WITH SINGLEMODE FIBER PIGTAIL ELECTRICAL/OPTICAL CHARACTERISTICS Parameter Threshold current Operating current Operating Voltage Symbol Ith Iop Vop CW CW CW,If=Iop (Note 1) CW,If=Iop CW,If=Iop CW,If=Iop Ib=Ith,10~90% (Note 2) Tc=0~75 C,APC CW,If=Iop,Vrd=3V Vrd=5V Vrd=5V,f=1MHz (Tc=25 C, unless otherwise noted) Test Conditions Min. 3 1.0 1285 0.1 Limits Typ. 7 20 1.1 2 1300 1.2 0.3 0.4 0.15 0.6 0.1 Max. 15 40 1.5 1330 4 1 1.5 0.5 20 mA mA V mW nm nm ns dB mW/m A mA mA pF Unit Optical output power from fib er Pf end Center wavelength Spectral (Note 3) bandwidth lc (RMS) Dl tr, tf (Note 4) Er h Imon Id Ct Rise and fall times Tracking error Differential efficiency Monitor current Dark current (Photodiode) Capacitance (Photodiode) Note 1.
