As telecom technology advances in the past few decades, the size of transceiver modules has become smaller and smaller. Meanwhile, the rate of optical transceiver also becomes faster and faster, for it is ranging from 1.25 G, 2.5 G, 4 G to 10G, 40G and 100G, etc. However, when it comes to 10G, people found that the encapsulation is too small to keep many components. Thus, XFP modules were launched in 2002 as a new standard to solve this problem. Next, this article will introduce the 10G XFP optical transceivers in great details.

Introduction of XFP Transceiver

In fact, XFP is not the first 10G transceiver in the market. The 10G transceiver market has gone through 300Pin and XENPAK/XPAK/X2 before XFP came out. As these types of...

In order to better satisfy the demands for high speed, wide bandwidth and high density, changes are taking place in the data center. Driven by the cloud services, the hyperscale/cloud data centers are becoming larger, more modular, more homogeneous with an architecture change from traditional 3-tier to flattened 2-tier topology. To deal with these changes and challenges, what will we need for optical interconnection a few years down the road? Here are the key trends to watch in 2016 which give you some guides to the roadmap.

Significant Increase in 100G & 25G Port Density

For easy understanding, we divide the data center into three parts—intra-rack, inter-rack and long span/inter-building. Within the data center rack, 10 GbE is...

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...

Since March 1999, 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 illustrate both the copper and fiber connectivity options for 10 Gigabit Ethernet.

Transceivers

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

DDM which stands for digital diagnostics monitoring is specified by the industry-standard SFF-8472. Modern optical SFP transceivers can support standard digital diagnostics monitoring (DDM) functions.which is also known as digital optical monitoring (DOM). What makes these transceivers with DDM/DOM function different from the traditional modules? This article will give you the answer.

What is Digital Diagnostic Monitoring (DDM)?

Very often, we can see GLC-LH-SMD, or on the label of modern transceivers. Actually, the “D” in GLC-LH-SMD represents the DDM function we are talking about today. When choosing fiber optical transceivers in the market, you may have the option with or without DDM/DOM. At present, most of high-end switches...

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...
