Within the optical communication marketplace, there are several sorts of fiber optic transceivers which are SFP, GBIC, X2 and so on. Cisco is really a brand that has great overall performance on fiber optic products.

As among the fundamental fiber optic transceivers, Cisco SFP is generally utilized in many locations. The inexpensive price and the higher performance, would be the benefits of Cisco SFP. As all recognized, the little form-factor pluggable (SFP) is really a compact, hot-pluggable transceiver utilized for each telecommunication and data communications applications. The type aspect and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It’s a popular industry format jointly created and supported by many network component vendors. Cisco SFP transceivers are designed to assistance SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Because of its smaller sized size, Cisco 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 within the MSAs.

So what’s GBIC? From the above paragraph we have known that GBIC is short for gigabit interface converter, which is a standard for transceivers, generally used with Gigabit Ethernet and fibre channel within the 1990s. By providing a regular, hot swappable electrical interface, 1 gigabit port can assistance a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of a huge selection of kilometers. Cisco GBIC is really a transceiver that converts serial electric signals to serial optical signals and vice versa. In networking, a GBIC is utilized to interface a fiber optic system with an Ethernet method, such as Fibre Channel and Gigabit Ethernet. Cisco GBIC enables designers to design one kind of device that can be adapted for either optical or copper applications. Cisco GBICs also are hot-swappable, which adds towards the ease of upgrading electro-optical communication networks.

To supply larger capacity, we require a Cisco X2 transceiver. Cisco X2 transceiver will be the 10G fiber optic transceiver, whose improvement was primarily based on former XENPAK standards. Cisco X2 10GB transceiver inner function is almost similar with XENPAK, and X2 also can use one transceiver to fulfill all 10G Ethernet optical port function. Cisco X2 transceiver is about half size of Xenpak, this enable it suit for density installations. Cisco X2-10GB-SR is one of the most well-liked Cisco X2 transceivers. Cisco X2-10GB-SR module is really a multimode transceiver target in the 10G applications. It works with 850nm multimode fiber and also the optical interface is duplex SC. Cisco X2-10GB-SR modules can hyperlink the equipment to fiber optic networks, max transmission distance is 300 meters and support a hyperlink of max 300 meters via multimode fiber. It is utilized in 10Gigabit applications including Ethernet and Fibre channel.

Except SFP, GBIC, X2, there are aslo other Cisco fiber optic transceivers with various use. Such as XENPAK transceiver which we’ve refered within the introduction of Cisco X2. For more information, you are able to go to Cozlink, who’s the very best fiber optic products supplier from China.

XENPAK

Overview

The range of Cisco 10GBASE XENPAK modules offers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.

Main features of Cisco 10GBASE XENPAK modules include:

• Supports 10GBASE Ethernet
  
• Hot-swappable input/output device plugs into an Ethernet XENPAK port of a Cisco switch or router to link the port with the network
  
• Provides flexibility of interface choice
  
• Supports “pay-as-you-populate” model
  
• Supports the Cisco quality identification feature that enables a Cisco switch or router to identify whether the module is a Cisco certified and tested XENPAK module
  
• Interoperable with respective Cisco 10-Gigabit X2, XFP and SFP+ modules on the same link.
