How does the XFP transceiver differ from the protocol converter?
2017-09-08
The XFP transceiver is only used for photoelectric signal conversion, and protocol converters are used to convert a protocol to another. XFP transceiver is a physical layer device, is the fiber into twisted pair device, there are 10/100 / 1000M conversion.

Protocol converter there are many, most of which is basically a two-tier equipment, often encountered a RAD protocol converter is 2M E1 line into V.35 data lines connected to the router equipment, of course, 2M turn Twisted pair Ethernet, with 2M communication lines can be achieved within the scope of remote access and expansion.

These two kinds of equipment on its maintenance is not much, as long as not burned generally not bad.

A router is a three-tier device, and you need to master the knowledge of many router configurations. Different brands use different methods, you need to have targeted learning.

XFP transceiver is a short distance twisted pair electrical signals and long distance optical signal interchangeable Ethernet transmission media conversion unit, in many places also known as photoelectric converter or fiber converter (Fiber Converter ).

XFP transceivers are generally used in the actual network environment where Ethernet cables can not be overwritten and must be used to extend the transmission distance, while also helping to connect the fiber's last mile line to the metro and more outer networks The role of. With the XFP transceiver, but also for the need to upgrade the system from copper to fiber, but the lack of funds, manpower or time to provide users with a cheap program. XFP Transceiver products must be in strict compliance with 10Base-T, 100Base-TX, 100Base-FX, IEEE802.3 and IEEE802.3u Ethernet, in order to ensure complete compatibility with network equipment such as network cards, repeaters, hubs and switches, Network standard. In addition, it should comply with FCC Part15 in EMC anti-electromagnetic radiation. Nowadays, as the major domestic carriers are building the community network, campus network and enterprise network, the amount of XFP transceiver products is also increasing to meet the needs of the access network.

XFP transceivers typically have the following basic features:
1. Provides ultra low latency data transmission.
2. Fully transparent to network protocols.
3. Using special ASIC chip to achieve data wire-speed forwarding. Programmable ASIC to a number of functions focused on a chip, with a simple design, high reliability, low power consumption, etc., can make the equipment get higher performance and lower cost.
4. Rackmount devices provide hot-swappable features for easy maintenance and uninterrupted upgrades.
5. Network management equipment can provide network diagnostics, upgrades, status reports, abnormal report and control functions, can provide a complete operation log and alarm log.
6. The device uses 1 + 1 power supply design, support ultra-wide power supply voltage, to achieve power protection and automatic switching.
7. Supports ultra wide operating temperature range.
8. Support complete transmission distance (0 ~ 120 km)

Simply put, the XFP transceiver is a converter that uses fiber as a physical medium and converts an Ethernet signal to an optical signal.
