BOARD EVALUATION
Make sure the power is off when making electrical
connections. The operators should be grounded before
touching the board to minimize the threat of Electro Static
Discharge (ESD). Power is applied after all the connections
have been made. Normal operation and initialization
process begins at power up.
The following items are useful for testing and evaluating the
ML6651 Evaluation Board:
•
Either of the two most popular optical fiber cable sizes,
50/125 micron or 62.5/125 micron multi mode fiber
cable can be used as the fiber link
•
Fiber optic power meters (850/1300nm wave length)
such as the Fotec Power meter
•
Fiber optic attenuators
•
An optical to electrical converter. Micro Linear uses
the BCP waveform receiver model 300
•
Network Interface Cards (NIC’s) or Netcom’s Fast
Ethernet (Smart Bits 2000) testers
•
Twisted-pair cables of various lengths (100m Ethernet
Standard: max 100m) with crossover wiring
•
The jumpers are installed as pre-configured
