What's the Difference Between Transceiver & Transponder? Computers Articles | March 4 Jared Goff Youth Jersey , 2015

Transceiver and transponder are devices which play important role in fiber optic transmission. They are similar but there are some difference between them. What's difference? We will tell you in the article.



In a fiber optic communication network, there are many equipment and facilities to support the normal operation of the system. Fiber optic transponder and fiber optic transceiver are the one of these devices. Literally, both of them are with a prefix "trans". It seems to imply that there is a similarity between them. Actually, they are not the same. So, what's the difference between them, something difference on principle or applications? Today Cooper Kupp Youth Jersey , we are going to have a discussion on this topic.


First, in order to better understand the difference between a fiber optic transceiver and a fiber optic transponder, we need to define what each one does.


Fiber Optic Transceiver Most systems use a "transceiver" which includes both transmission and receiver in a single module. Its purpose, in broad terms, is to transmit and receive data. In fiber optic communication, the commonly used transceiver modules are hot-swappable IO (inputoutput) devices which plug into module sockets. The transceiver acts to connect the electrical circuitry of the module with the optical or copper network. Devices such as routers or network interface cards provide one or more transceiver module slot (e.g GBIC Gerald Everett Youth Jersey , SFP, XFP), into which you can insert a transceiver module which is appropriate for that connection. The optical fiber, or wire, plugs into a connector on the transceiver module. There are multiple types of transceiver module available for use with different types of wire, fiber Todd Gurley II Youth Jersey , different wavelengths within a fiber, and for communication over different distances. The most commonly used fiber optic transceivers include GBIC, SFP, SFP+, XFP, CFP Aaron Donald Youth Jersey , QSFP etc. They are widely used for different application, eg. 10G, 40G fiber optic transmission.


Fiber Optic Transponder?"Transponder" includes a transmitter and a responder. It is a similar device with transceiver. In optical fiber communications, a transponder is the element that sends and receives the optical signal from a fiber. A transponder is typically characterized by its data rate and the maximum distance the signal can travel. According to its specific applications, it is also known as wavelength-converting transponder, WDM transponder or fiber to fiber media converter. Fiber optic Transponders extend network distance by converting wavelengths (1310 to 1550) Eric Dickerson Youth Jersey , amplifying optical power and can support the “Three Rs” to Retime, Regenerate and Reshape the optical signal. In general, there is an O-E-O (optical-electrical-optical) function with this device. Fiber optic transponders and optical multiplexers are usually present in the terminal multiplexer as an important component for WDM (Wavelength Division Multiplexing) system. In addition, in nowadays market, many transponders are designed as protocol and rate-transparent fiber media converters that support SFP, SFP+ and XFP transceivers with data rates up to 11.32 Gpbs Greg Gaines Womens Jersey , and with seamless integration of different fiber types by converting multi-mode fiber to single-mode fiber, and dual fiber to single-fiber.


Fiber Optic Transceiver vs Fiber Optic Transponder A transponder and transceiver are both functionally similar devices that convert a full-duplex electrical signal in a full-duplex optical signal. The difference between the two is that fiber transceivers interface electrically with the host system using a serial interface, whereas transponders use a parallel interface. So transponders are easier to handle lower-rate parallel signals, but are bulkier and consume more power than transceivers. In addition, transceivers are limited to providing an electrical-optical function only (not differentiating between serial or parallel electrical interfaces), whereas transponders convert an optical signal at one wavelength to an optical signal at another wavelength.
