10 Gigabit Ethernet (10GbE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10 Gigabit Ethernet defines only full duplex point-to-point links which are generally connected by network switches. 10G connection in telecommunication network is gradually moving from the backbone to layer 2 and layer 3. Both technology and market of 10G optics modules are mature: the 10G optics modules have advanced from XENPAK which is the first generation of 10G transceiver to SFP+ which is now the most popular 10G optics. Besides, the price of 10G modules is becoming lower. Some genius guys even...

Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. Compared with copper cable, fiber optic cable can support longer transmission distance, high speed, high bandwidth, etc. However, not everything is perfect. There are still some factors that may influence the transmission distance over fiber cables. This article will introduce the most common factors that limit the data transmission distance.

Fiber Optic Cable Type

Generally speaking, the maximum transmission distance is limited by dispersion in fiber optic cable. There are two types of dispersion that can affect the optical transmission distance. One is chromatic dispersion, which is the...

In the past few decades, the Ethernet industry has been working on providing solutions to increase the speed of Ethernet from 1 to 10 gigabits per second. For enterprise LAN applications, 10 Gigabit Ethernet enables network managers to scale their Ethernet networks from 10 Mbps to 10,000 Mbps, while leveraging their investments in Ethernet as they increase their network performance. There are various types of cables and transceivers available for making Ethernet connections at speeds of 10 Gigabit per second. This article will introduce both the copper and fiber connectivity options for 10 Gigabit Ethernet.

Transceiver Options

Standards bodies initially offered several options for the 10-Gigabit transceiver. The one that ultimately...

Introduction to SFP+ Transceiver

In the 10 Gigabit Ethernet world, fiber optical transceivers have been developed along the way to meet the increasing usage and demand for higher-performance servers, storage and interconnects. The small form-factor pluggable plus (SFP+) can be referred to as an enhanced version of the SFP that supports data rates up to 16 Gbit/s. SFP+ supports 8Gbit/s Fiber Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format supported by many network component vendors. In order to ensure the high performance of the SFP+ transceivers, one critical point is to deal with the testing issues of them. This article will first illustrate the SFP+ testing challenges in...

Data center has now become one of the most critical and dynamic operations in any business. With all the data processing and transmission, it is only critical that every design aspect and component of your data center is properly optimized, including its fiber optic transceiver technology. The transceiver and other optical components need to meet varied bandwidth requirement for storage, switch, and server applications. Now let’s see how the optical transceivers will promote data centers in the future.


Small Package Makes Sense

Optical transceivers are becoming smaller, but more powerful, which makes them an important piece in server technology. In fact, even though a transceiver is physically small, it can handle a network...

A small form-factor pluggable (SFP) is a type of transceiver device that has been standardized by the MSA (multi-source agreement). The MSA will define the characteristics of the system and is typically an agreement between multiple manufacturers. The agreements guarantee that any SFP or SFP+ device from any vendor will function properly. This article will give you a more comprehensive introduction to the SFP and SFP+MSA.

An Overview of Pluggable Optical Transceiver MSA Standards

Both SFP and SFP+ optical transceivers are standardized by MSA. These documents strictly define sufficient characteristics of an optical transceiver so that system (like Ethernet switch, Router, and media converter) vendors may implement ports on their...

10 Gigabit Ethernet or 10GbE is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. Nowadays, 10 Gigabit Ethernet is gaining broader deployments by the increasing bandwidth requirements and the growth of enterprise applications. In the world of 10 Gigabit Ethernet, selecting the appropriate 10-gigabit physical media is a challenge, because 10GbE is offered in two broad categories: optical and copper. This article will introduce both optical and copper cabling options for 10 Gigabit Ethernet.

Fiber Optical Cabling

Single-mode fiber (SMF), typically with an optical core of approximately 9 μm (microns), has lower modal dispersion than multimode fiber. It is able to support...

Choosing the best type of SFP+ transceivers and cables is not always easy. You can approach the selection process by reviewing the device as a single entity or you can explore the fiber cable separately. In order to select SFP+ modules and cables effectively, it is important to know the standards set forth by the IEEE 802.3 committee. According to the IEEE 802.3 standard, the 10 Gigabit Ethernet has been ratified and is compatible with MMF and SMF transceivers. which means that the signals can maintain their signal integrity when transmitting long distances. This article will give some tips that help you make a good selection for your SFP+ modules and cables.

Ensure They are Interchangeable or Hot-Swappable

Plug-and-play is a technology that allows the operating system to detect and configure internal and external peripherals as well as most adapters. It has the ability to find and configure hardware components without having to reset DIP (dual in-line package) switches and jumpers. Plug-and-play transceivers refer to hot-swappable or hot-pluggable optical transceivers, such as SFP transceivers or XFP transceivers, which can be quickly plugged into an interface of fiber optical devices. Here are the reasons why plug-and-play transceivers play such an important role in data center communications.
