From the origin of 10G Ethernet, 10G optical transceivers have been developed along the way to meet the increasing demand for higher-performance servers, storage and interconnects. However, selecting the best type of 10G optical transceivers is not always easy. There are a variety of factors that must be considered. To be able to select a matching transceiver for a given application and hardware, all below stated parameters must be considered.

Transceiver “form-factor” / MSA Type

The transceiver has to mechanically and electrically fit into a given switch, router etc. Transceiver MSAs define mechanical form factors including electric interface as well as power consumption and cable connector types. XENPAK is the first MSA for 10...

Pluggable fiber optic transceivers refer to hot-swappable or hot-pluggable optical transceivers which can be quickly plugged into an interface of fiber optical devices. An optical transceiver can best be described as a device that converts high-speed data from a cable source to an optical signal for communication over optical fiber. Optical transceivers are used to update the communications networks to manage broadband, to update the data center networks to make them manage traffic with higher speeds, and to implement the backbone network for mobile communications.

Pluggable fiber optic transceivers provide connectivity options for Ethernet over twisted pair copper and fiber optic cables with transition speeds from 100 Megabits per...

In order to cut down the costs on the expensive SFP transceiver modules, many users are seeking for a compatible SFP to use. For example, if your network contains HP routers, firewalls, and switches, you might think that only HP SFP branded transceivers will ensure your equipment functions optimally. However, that seemingly reasonable assumption could cost your company thousands of dollars. Compared to the compatible SFP transceiver produced by third-party companies, HP SFP transceiver comes with dramatically inflated price tags while a third-party compatible one is roughly 80 percent less expensive than HP branded SFP transceiver. Although price isn't everything, it's important to know that you're getting your money's worth. That calls...

From the origin of 10G Ethernet, optical transceivers have been developed along the way to meet the increasing demand for higher-performance servers, storage and interconnects. SFP+ transceiver is an enhanced version of SFP that supports data rates up to 10 Gbit/s. 10G SFP+ transceiver is a popular industry format supported by many network component vendors. In comparison to earlier XENPAK or XFP module, SFP+ transceiver is more compact and leaves more circuitry to be implemented on the host board instead of inside the module. This article will introduce the 10GbE optical standards and the most common types of 10G SFP+ transceivers.

In the 10 Gigabit Ethernet world, fiber optical transceiver modules have been developed to meet the increasing demand for higher-performance servers, storage and interconnects. XENPAK was the first MSA for 10GE and had the largest form factor. X2 became the later competing standard with smaller form factor, among which there are X2-10GB-SR, X2-10GB-LR, X2-10GB-ER and X2-10GB-ZR series. XFP came after X2. Then smaller SFP (small form-factor pluggable) enabling greater port density followed the XFP. The newest module standard is SFP+ transceiver (the enhanced small form-factor pluggable transceiver) which has become the most popular socket on 10GE systems.

1000BASE is a term describing various technologies for transmitting Ethernet frames at a rate of a 1,000,000,000 bits per second, as defined by the IEEE 802.3-2008 standard. 1000BASE SFP transceiver is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber optic network. It can be intermixed in combinations of IEEE 802.3z- compliant 1000BASE-SX, 1000BASE-LX/LH (GLC-LH-SM or GLC-LH-SMD), or 1000BASE-ZX interfaces on a port-by-port basis. Here are the most common types of 1000BASE SFP transceiver modules.

1000BASE-LX SFP Transceiver

LX stands for long wavelength. 1000BASE-LX is a physical layer specification for Gigabit Ethernet over fiber optic cabling as defined in 802.3z....

In order to cut down the costs on the expensive SFP transceiver modules, many companies are seeking for Cisco SFP alternatives to use. When choosing SFP transceivers, many people often run into several frequently asked questions involving the Cisco Catalyst line of switches, and whether we can use a Cisco compatible SFP (a 3rd party SFP) with them. Here are some common questions we might have when using a 3rd party SFP transceiver. And from the answers, we might have a deeper understanding of using these 3rd party SFP transceivers.
