Definition:A gigabit interface converter (GBIC) is a standard for transceivers, commonly used with Gigabit Ethernet and fibre channel in the 2000s. By offering a standard, hot swappable electrical interface, one gigabit port can support a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of hundreds of kilometers.The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the SFF Committee. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fibre optic or copper networking cable. It is a popular industry format jointly developed and supported by many network component vendors. SFP transceivers are designed to support SONET, gigabit Ethernet, Fibre Channel, and other communicati..
The word GBIC is an IT industry term which stands for Gigabit Interface Converter. A GBIC is a variety of Optical Transceiver, which is designed to convert serial electric signals into serial optical signals. GBIC modules are typically inserted into a network switch in order to connect a Fiber Optic system with an Ethernet system. The most common applications where GBIC modules are used include Fibre Channel and Gigabit Ethernet.The GBIC is fully hot swappable, which adds to its flexibility and ease of installation. It has become a standard form factor for optical transceivers, and can support a variety of physical media, from legacy copper to long wave single mode fiber up to lengths of hundreds of kilometers. Cisco GBIC modules and 3rd party equivalent, MSA (Multi Source Agreement) compliant modules can be interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-CWDM, or 1000BASE-DWDM..
DefinitionXENPAK is a multi source agreement (MSA), that defines a fiber-optic or wired transceiver module which conforms to the 10 Gigabit Ethernet(10GbE) standard of the Institute of Electrical and Electronics Engineers (IEEE) 802.3 working group. The MSA group received input from both transceiver and equipment manufacturers during the definition process. XENPAK has been replaced by more compact devices providing the same functionality.“GBIC” stands for “Gigabit Interface Converter” and was quite popular in the 1990s. It served as a standard way of connecting to different media like copper and fiber optic cables. The main difference between GBIC and XENPAK is their size. SFP is considerably smaller than GBIC.The difference in size is very desirable for many people, especially for those who deal with lots of them, because it will take up a lot less space. Nowadays, GBIC is considered to be obsolete, and you would be hard pressed to find vendors that still carry equipment t..
Understanding Cisco GBIC and SFP ModulesCisco GBIC (GigaStack Gigabit Interface Converter) is a general-purpose, low-cost Gigabit Ethernet stacking module provides high-speed connectivity between the Cisco switches, either the establishment of high-density port stacking, but also with the server or thousandsmegabit connection to the backone for fast Ethernet to Gigabit Ethernet transition, providing a low-cost, high-performance alternative. In addition, by means of the optical fiber, but also with remote high-speed backone network connection. GBIC module is divided into two categories, one is the ordinary cascade using GBIC module, and another is stacked special GBIC module.Cascading GBIC moduleCascade using GBIC module is divided into four kinds:1000Base-T GBIC module, suitable for five or six super twisted pair, the maximum transmission distance of 100 meters.1000Base-SX GBIC module for multimode fiber (MMF), the maximum transmission distance of 500 meters.1000Base-LX/LH GBIC module ..
