How to Check SFP Module Optical Signal Strength?

SFP optical transceiver is a hot-swappable, compact component that provides fiber connectivity for optical networking. They support various applications like Fibre Channel (FC) switches, SONET/SDH network, Gigabit Ethernet, high-speed computer links, and CWDM and DWDM interfaces. When connected to switches, the optical signal strength of SFP modules is a critical parameter to ensure the normal working of the whole connections. This article will introduce the method of SFP module signals measurem...

Understanding of 10GBASE-T SFP+ Copper Transceiver Modules

With the broad adoption of network function virtualization (NFV) and unified data and storage networking toady, servers are now seeing increased I/O demands. To keep pace with the increased I/O demand, network access line rates have migrated from 1Gb/s to 10Gb/s. Several connectivity solutions exist to service these network access needs including direct attach cables (DAC), optical transceiver modules and 10gbase-t sfp+ transceiver. Each comes with its own set of distinct advantages and disadvan...

Choose 10GBASE-T Copper Over SFP+ for 10G Ethernet

With the increase in server consolidation through virtualization in the data center, the resulting data demand has exceeded the traditional 1Gb/s throughput capability. 10G Ethernet, which can simplify network infrastructure by consolidating multiple gigabit ports into a single 10GbE connection, is considered to be an ideal solution to overcome the aforesaid bandwidth limitation. Generally, 10GbE network can be achieved both by 10GBASE-T copper and SFP+ cabling. This post will discuss why to cho...

10 Gigabit Ethernet Overview

10 Gigabit Ethernet, known as IEEE 802, was first ratified in 2002. With the increasing bandwidth requirements, numbers of large enterprises have started deploying 10GbE in their corporate backbones, data centers and server rooms to support high-bandwidth mission-critical applications. Over the years, improvements in 10GbE technology is extending its reach beyond enterprise data centers to broader market. However, do you really get to know what 10 Gigabit Ethernet means? What Is 10 Gigabit ...

A Quick Overview of Cisco GLC-LH-SM SFP Module

GLC-LH-SM is the Cisco 1000Base LX/LH SFP transceiver module, which is one of the most commonly used SFP module. It is hot-swappable and designed to plug directly into SFP/GBIC interface port or slot in your router and switch for Ethernet & Fibre Channel network applications. But in Match, 2013, Cisco announced the end-of-sale for GLC-LH-SM and substituted it with GLC-LH-SMD. But nowadays, there are still third party suppliers providing GLC-LH-SM SFP module, and there are still research resu...

How Many Types of SFP Transceivers Do You Know

Gigabit Ethernet (GE) came into use in 1999 and has been gradually supplanting Fast Ethernet (FE) in wired local networks, due to the fact of being considerably faster. The transmission hardware used for connecting GE supported devices retains the compact Small Form-factor Pluggable (SFP) package. SFP is often called mini-GBIC (Gigabit Interface Converter). Because it is smaller size and has replaced GBIC modules in most 1Gb applications. The initial Gigabit Ethernet hardware standard was produc...
