Product Overview

AFBR-POL2120 is a high-power laser module (HPLM) specifically designed to be used with the Broadcom optical power converter, AFBR-POC20xL. The AFBR-POL2120 is equipped with a pigtail fibre and an FC/PC optical connector. It consists of a laser chip, operating typically at 808 nm wavelength at a case temperature of 25°C. The hermetically sealed package protects the laser chip from any harsh environment. Applications include sensor applications: provide isolated power for various sensors, electric power utilities: deliver isolated power to protect sensor devices, lightning: protect key circuits, RF power electronics circuits: reduce capacitive coupling and interference, oil and gas industry: eliminate the risk of sparks, chemical plants: use PoF in corrosive areas where metal wires can be attacked, aerospace: reduce weight, EMI and the risk of sparks, medical instrumentation: magnetic resonance imaging (MRI) and security: trigger and power sources unaffected by EMI-RFI.
  • 808nm high-power 2W laser module
  • Hermetically sealed package
  • Average optical output power of 2W at room temperature
  • FC/PC port with a pigtailed 0.22 NA fibre
  • Designed for Broadcom optical power converter products for Power over Fibre (PoF) applications
  • Small footprint board mounting package
  • 2 electrical pins (anode and cathode)
  • Operating case temperature range from +15 to 45°C, typical operating current of 2.4A
  • Typical CW output power of 2W, centroid wavelength of 808nm typical
  • Typical forward voltage of 1.85V, wavelength shift vs. temp is 0.3nm/°C


A proper heat sink for thermal dissipation of device is highly recommended and can greatly enhance lifetime. Heat dissipation mounts with thermal resistance of lower than 0.3°C/W are recommended.


Invisible laser light from this device can be very harmful to the human eye. Use dedicated Laser class 4 safety eye protection glasses during operation.
