XFP and SFP are both transceiver standards for fiber optic networking. XFP was defined in 2002 for 10 Gigabit connections and uses an LC connector. It is hot-swappable and supports applications like 10 Gigabit Ethernet and OC-192 SONET. SFP was developed for smaller form factor pluggable transceivers up to 5 Gbps for easy upgrading of networks. It supports standards like Gigabit Ethernet, Fibre Channel, and SONET. Due to its smaller size, SFP replaced the GBIC transceiver standard.
Difference Between XFP & SFP
- 1. Difference Between XFP & SFP
- 2. What is XFP…? The XFP (10 Gigabit Small Form Factor Pluggable) is a standard for transceivers for high- speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other electrical components which is called XFI. A transceiver is a device comprising both a transmitter and a receiver which are combined and share common circuitry or a single housing.
- 3. XFP Detail 1. XFP modules are hot-swappable and protocol- independent. 2. They typically operate at optical wavelengths (colors) of 850 nm, 1310 nm or 1550 nm. 3. Principal applications include 10 Gigabit Ethernet, 10 Gbit /s Fibre Channel, Synchronous optical networking (SONET) at OC-192 rates, Synchronous optical networking STM-64, 10 Gbit /s Optical Transport Network (OTN) OTU-2, and parallel optics links. 4. They can operate over a single wavelength or use dense wavelength-division multiplexing techniques. 5. They include digital diagnostics that provide management that were added to the SFF-8472 standard. 6. XFP modules use an LC fiber connector type to achieve high density.
- 4. What is SFP…? The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. It interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is a popular industry format jointly developed and supported by many network component vendors.
- 5. SFP Detail 1. SFP transceivers are expected to perform at data speeds of up to five gigabits per second (5 Gbps), and possibly higher. 2. Because SFP modules can be easily interchanged, electro-optical or fiber optic networks can be upgraded and maintained more conveniently than has been the case with traditional soldered-in modules. 3. Rather than replacing an entire circuit board containing several soldered-in modules, a single module can be removed and replaced for repair or upgrading. This can result in a substantial cost savings, both in maintenance and in upgrading efforts.
- 6. Count… SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsoletes the formerly ubiquitous gigabit interface converter (GBIC); the SFP is sometimes referred to as a Mini-GBIC although no device with this name has ever been defined in the MSAs.
