Product Overview:

1450nm, 15mW CW and 45mW Pulsed, Narrow Linewidth DFB Laser

LD4B-1450-DFB-2.5G-15-COAXB-2-SM1-FA-CW-1.0 is an InGaAsP MQW laser diode coupled to an optical fiber. The special feature of the LDS technology is the increased thermal stability of optical power.
    • Wavelength 1450 nm
    • Cavity type DFB
    • Linewidth < 500 kHz
    • Data rate up to 2.5 Gbps
    • Optical power up to 15 mW in CW mode and up to 45 mW in pulse mode in the single-mode fiber G.657.A1
    • Typical thermal stability of optical power (tracking error) 0.15 dB
    • Package type fiber-coupled coaxial
    • Built-in monitor photodiode

Proper Handling and Operation of Diode Lasers

Diode lasers are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
