3.1.3 - Transceiver Mismatch Issues

Flashcards about Duplex, Parallel, and Wavelength Division Multiplexing transmissions, as well as transceiver mismatch issues.

How does Duplex transmission work?

Duplex uses two strands for transmit (Tx) and receive (Rx).

How does Parallel transmission work?

Parallel uses multiple strands (typically eight or twenty) to implement Tx and Rx channels.

How does Wavelength Division Multiplexing work?

Wavelength Division Multiplexing uses either a single bidirectional strand or dual unidirectional strands to implement multiple channels, distinguished by wavelengths.

What is the purpose of modular transceivers?

Modular transceivers are designed to be used with a specific type of optical fiber.

What type of light source do single mode fiber transceivers use?

Laser diodes.

What type of light source do multimode fiber transceivers use?

LEDs or a different type of laser (VCSEL).

What are some common optical wavelengths used by transceivers?

850 nm, 1300 nm, or 1550 nm.

Why is it important to check the manufacturer's documentation for the interface?

To ensure the correct fiber type is used, not only for the fiber optic cable, but also for the fiber patch cords used to connect to it at each end.

What can mismatches between cable, patch cords, and interfaces lead to?

Significant signal loss.

When using BiDi transceivers, what must be considered?

The Tx wavelength used by one transceiver must connect through to the same wavelength on the other transceiver's Rx port.
