Miniature Laser Diode Driver PCB boards

New PCB boards are now available from Access Pacific as part of an expanding series of low cost, versatile, time saving, and essential drivers for laser diodes. These new pcb types are small, but complete and ready to use. They can be utilised either as a stand alone unit for each LD that is powered up, or can be built into a general purpose driver in a small box or suitable housing.

Units now available include:

  • Type: K2D - 6.25mm x 20mm 60mA capability for N type Laser Diodes
  • Type: W01 - 7mm x 11 mm 70mA capability for N type Laser Diodes
  • Type: 200/P01 - 14mm diameter 200mA capability for N type Laser Diodes

These driver boards can be powered by batteries or the usual bench power supply. Ideal for experimental setups, or low cost evaluation. They are not intended to be a substitute for our more fully equipped bench driver/power supplies, but are capable of invaluable work in quite advanced systems.

New Product, Optical transceivers for most applications.

Typical specification:

  • Data rate 1.25Gbps
  • 850, 1310, 1550nm CWDM/WDM
  • Transmission distance up to 120km
  • Duplex LC receptacle
  • Compatible with SONET OC-24-LR-1
  • Digital diagnostic monitor
  • Internal/External calibration
  • 500m with 50/125 MMF
  • 300m with 62.5/125 MMF
  • ROHS
