Entering Telcordia Optical Devices
When a Telcordia model is selected for the calculation, the parameters that you must enter for an optical device vary based on subcategories. Telcordia Issue 1 and prior Bellcore models support the following subcategories of optical devices:
Coupler / Splitter
Detector, Isolator, Emitter
Laser Module
Other Optical Module or Device
Wavelength Division Multiplexer
Telcordia Issue 2 supports all of the subcategories listed below.
Amplifier
Coupler / Splitter
Detector, Isolator, Emitter
Dispersion Compensating Module
Laser Diode
Laser Module
Modulator
Optical Wavelength Locker
Other Optical Module or Device
Power Coupler / Divider (Tap)
Transceiver
Transponder
