QUESTION: Design an optical transceiver system to transmit a 2Gbit/s data over a 5000 km path. The line coding technique used is Return to Zero (RZ) and the error rate must be 10-9 or better.

You need to choose and list down in detail the main important components used in your design such as optical sources, fiber cable types and optical detectors. The parameter values for these components should be the actual values which can be obtained from any textbook or online datasheets.

NEED TO get these two answers: 1) Design Specification

2) Optical Sources (Give multiple choices of Optical Sources with its specification such as input power, rise time, wavelength and state its reference)

Summary in a table

- Rise time must below 0.1ns

Example:

Source Type	Pi = Mean Input Power Launched into Fiber	Risetime (ns)	Wavelenth (nm)	Reference
Laser
