CHAPTER 4: CONNECTING TO DEVICES AND NETWORKS
Fiber optic serial connections
For devices located some distance from the D400, they may be connected using glass or
plastic optical fiber cables. Fiber optic cabling also offers superior performance in
electrically noisy environments.
Glass optical fiber
You can use the following glass optical fiber (GOF) cabling with the D400 Glass Optical
Fiber Serial adapter:
•
50/125 µm core/cladding multi-mode (gradient index) cable
•
62.5/125 µm core cladding multi-mode (gradient index) cable
•
100/140 µm core/cladding multi-mode (gradient index) cable
•
200 m core Hard-Clad Silica (HCS) multi-mode (step index) cable
You can use the following fiber optic terminations for D400 cabling:
•
ST Connectors
When calculating cable length, consider the following optical power levels:
•
Glass optical fiber transmitter power is –19.0 ± 2 dBm
•
Glass optical fiber receiver sensitivity is typically –31.0 dBm over life of our product.
LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class
1M. Class 1M devices are considered eye safe to the unaided eye. Do not view directly
with optical instruments.

Plastic optical fiber
You can use 1 mm plastic optical fiber (POF) cabling with the D400 Plastic Optical Fiber
Serial adapter. The recommended termination is the Agilent Versatile Link Simplex
Connector.
When calculating cable length, consider the following optical power levels:
•
Plastic optical fiber transmitter power is –9.0 ± 4.5 dBm
•
Plastic optical fiber receiver sensitivity is typically –39 dBm
LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class
1M. Class 1M devices are considered eye safe to the unaided eye. Do not view directly
with optical instruments.
