LT3Dxx series Coaxial Laser use InGaAsP/InP MQW chip. The DFB laser integrated an InGaAs monitor PD, it can be used with appropriate feedback control circuitry to set optical power level for the DFB laser, As the current changed above the threshold, the optical power will change accordingly.

They are widely used in CATV or CDMA system. The laser diode is mounted into a coaxial package with single mode fiber pigtail. FC/UPC, FC/APC, SC/UPC or SC/APC connector can be selected.

Features

• 1310 nm transmitter with uncooled DFB-LD
• Low noise, low distortion, high linearity
• Coaxial Pigtail Package
• operating temperature range: -20°C to 80°C

Application

• CDMA/GSM transmission system
• WDM system
• Other analog transmission system
