4.5Fiber Optic 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 µm 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 –25.4 dBm

Warning: 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
