Transceiver Mismatch Issues
- modular transceivers are designed for a specific type of optical fiber
- single mode fiber transceivers use laser diodes
- multimode fiber transceivers use LEDs or VCSEL
- different transceivers work at different wavelengths and support different Ethernet standards and bit rates
- important to use proper fiber patch cords, transceivers, and cables
- 3 ways to deploy fiber:
- duplex
- uses two strands for transmit (Tx) and receive (Rx)
- parallel
- uses multiple strands (8 or 20) to implement Tx and Rx
- WDM
- uses either a single bidirectional strand or dual unidirectional strands to implement multiple channels, distinguished by wavelength
- each type is implemented by a different transceiver
