The Quad Small Form Factor Pluggable Double Density (QSFP-DD) MSA Group (Multi Source Agreement Group) announced the release of an updated 4.0 Hardware specification for the QSFP-DD form factor at September 18, 2018. The latest hardware specification to address the industry need for an improved high-density, high-speed networking solution. Other notable features to the updated […]
Cable Size and Cable Weight: Controlling noise and crosstalk at higher frequencies has required Category 6A cables up to 50% larger than their Category 6 predecessors. While many available Category 6A options remain significantly larger and heavier, the newest Category 6A cables are only about 15% larger than Category 6. Installation Complexity Most Category 6A […]
Permanent Link Certification When is permanent link testing appropriate? The permanent link test is used to certify the permanent cabling infrastructure and is typically conducted during the installation phase of the network. Adapter Required: Permanent Link Adapters Patch Cord Certification When is patch cord testing appropriate? Patch cord testing is used to quickly verify whether […]
Do not placing the multiple bundles or over-bunding the cables, it might increase the loss of the cable, or damage the jacekt. Avoid over bending the fiber cable, it is not copper cable, and considering to use bending insensitive cable to avoide bending loss Avoid mounting cabling components in locations that block access to other […]
TIP 1: Transmission Speed and Transmission Distance As for Fiber, there are Single Mode fiber and Multimode Fiber, the single mode fiber is for long distance transmission. while for Multimode fiber, it is usually used for intra-racks or short distance area cabling, however, when you are choosing MMF as the installation cable, be sure you […]
OTAP splitters (MTP/MPO interface) are hardware tools that allow you to monitor your network. The Optical TAP with 50:50, 60:40 or with a customized splitting ratio, which could 100% copy your network data to the monitoring site. The Fiber TAPs are passive (non-powered), that will not cause the live network devices to lose the link […]
As networking equipment becomes denser and port counts in the data center increase to hundreds and thousands of ports, managing cables connected to these devices become a difficult challenge. Traditionally, connecting cables directly to individual ports on low port-count equipment was considered manageable. Applying the same principles to high port-count equipment made the task more […]
For each of the required TIA and ISO structured cabling measurements, you will find troubleshooting tips to help quickly pinpoint the cause of failures when they occur. In some examples, you will find suggested reasons why the measurement does not fail in cases you would expect to see a failure. Wiremap Test Result Possible Cause […]
The following table helps you to understand more clearly about the categories of Ethernet cable. Items Category 5 / cat5 Category 5e / cat5e Category 6 / cat6 Category 6a / cat6a Category 7 / cat7 Category 8 / cat8 Applicable for Phone YES YES YES YES NO NO Applicable for Office Network YES YES […]
What will the 400G BiDi MSA group define? The MSA group is dedicated to defining optical data link specifications based on a dual wavelength bidirectional transmission technology on multimode fiber (MMF) that enables a reduction in fiber count relative to other solutions. The 400 Gbps BiDi solution leverages both the widely adopted 40 Gbps and […]
