Study Notes
- Media converters are used to convert signals of one media type to another at OSI layer 1.
- Can be used to extend copper connections over long distances by converting them to fiber, and vice versa.
- Media converters have a power connector on the back.
- In a switch with five copper interfaces, a media converter is used to connect to a fiber connection.
- Media converters can be stacked together in larger implementations, allowing for modular interface conversions.
- Transceivers, which contain both transmitter and receiver, allow for plugging in specific connection types.
- Transceivers come in various types and form factors, such as SFP, SFP plus, QSFP, and QSFP plus.
- SFP is a common connector for 1-gigabit fiber connections, while SFP plus supports increased throughput of up to 16 gigabits per second.
- QSFP fits four times the amount of information as an SFP, supporting four 1-gigabit connections or a total of 4 gigabits of throughput through a single QSFP.
- Bidirectional transceivers, such as BiDi transceivers, allow for both sending and receiving traffic over a single strand of fiber.
- QSFP plus supports four channels of increased throughput, making it ideal for 10-gig Ethernet links.
- Efficiency is increased by using larger form factor transceivers and bidirectional transceivers, effectively doubling throughput through a single connection.
