| TZ7-01-192B (1/5) Aug 16, 2001 Preliminary APPROVED APPROVED APPROVED A.Adachi T.Onodera Preliminary specification of 10Gb/s EML module Type No.=FU-641SEA-1M5 (Dispersion=1200ps/nm) Type No.=FU-641SEA-1M6 (Dispersion=1600ps/nm) B x DATE 18,Aug.'01 A C D Approved T.Nambara MITSUBISHI ELECTRIC CORPORATION TZ7-01-192B (2/5) FEATURES Input impedance is 50 Integrated Electro-absorption Modulator Distributed feed-back(DFB) Laser Diode Emission wavelength is 1.55m band Single mode optical fiber pigtail Built-in optical isolator Built-in thermoelectric cooler 7-pin Butterfly package with K connector 1. Absolute maximum ratings Parameter Laser diode Optical output power Forward current Reverse voltage Modulator Reverse voltage Forward voltage Photodiode for Reverse voltage monitoring Forward current Thermoelectric Current cooler(Note1) Voltage Operating case temperature Storage temperature Symbol Pf If Vrl Vrm Vfm Vrd Ifd Ipe Vpe Tc Tstg Condition CW CW CW Rating 6 200 2 5 1 20 2 1.5 3 -2070 -4085 Unit mW mA V V V V mA A V C C Note1 Even if the thermoelectric cooler (TEC) is operated within the rated conditions, uncontrolled current loading or operation without heat sink may easily damage the module by exceeding the storage temperature range. Thermistor resistance should be properly monitored by the feedback circuit during TEC operation to avoid the catastrophic damage. MITSUBISHI ELECTRIC CORPORATION TZ7-01-192B (3/5) 2.
