When Good Networks Go Bad, Part II

Last month my blog addressed, “ Why Good Networks Go Bad”, from a Layer 1, hardware perspective. I discussed why it is easy to jump to a higher layer of troubleshooting---especially when managed end devices such as Ethernet switches are installed- but Layer 1 is the right place to start. Many times an Ethernet network problem can easily be resolved. However, once you have tested cables, checked LED status, and other hardware-related steps, it is time to move up to the next steps for troubleshooting. BBAdmin | 12/19/2016 11:48:46 AM | 1 comments

When Good Networks Go Bad

Problems can occur anywhere in the network.  In this article I am going to focus on just a few of the issues that could be slowing a network down, creating instability, or actually crashing the network.

Loopback Tests and Media Converters

We often receive a desperate call at the end of a business day, after an installer has spent all day trying to figure out what is wrong with a network installation. The first product he will look at is the Ethernet media converter. By following  the simple steps lin this article, he can find out whether the media converter is a problem at the physical level.

OM3/OM4 Fiber

Fiber is shaped by the speed it has to support. The greater the speed, the less the distance is covered.  So while OM4 can support up to 550m at 10G, it is reduced to 150m for 40G and 100G. The typical protocols, FibreChannel and Ethernet, are shown below for speed to distance values

Troubleshooting Features on Media Converters

B+B SmartWorx offers an updated White Paper on the troubleshooting features for our media converter product lines; while there are various troubleshooting  features, they are product-specific; to ensure the features are available and set up properly, please refer to the product manuals located on the website.

Link Fault Pass-Through

Link Fault Pass Through, LFPT,  is a troubleshooting feature that combines TX LinkLoss (Twisted Pair, copper interface) and FX LinkLoss (Fiber, fiber interface) from both the local and remote IMC Networks media converters, when used in pairs.  This feature, when enabled, will pass a link fault through the device at each segment.  If a link fails on one interface of the media converter, the media converter will force the link down on its link partner and then forward it to the next interface.  The fault will be carried onto the local end.  LFPT can be enabled via DIP Switches or through SNMP management (if the product supports it).

The Case for Carrier Ethernet

Carrier Ethernet is necessary, given our local, continental and global connectivity. Last night I was at a baseball game, and saw people chronically on their cell phones and one even reading a Kindle. Meanwhile, digital signage displayed the player at bat and all his personal statistics. Clearly there was no interruption of services at the stadium!  Carrier Ethernet’s promise is to ensure that all services, no matter the type, will be consistently delivered.  Susan Stanley | 9/15/2014 12:20:54 PM | 1 comments

Advantages of Using Managed and Manageable Media Converters

B&B Electronics offers an array of Fiber Optic media converters, both in a managed and unmanaged form factor.  Media converters generally live in Layers 1 and 2 within the 7 OSI Layers. But media converters have evolved in the last 15 years, and their capabilities can contribute to the overall supervision of a network.   Susan Stanley | 7/7/2014 1:37:55 PM | 0 comments

Testing and Troubleshooting Media Converters

Installers and integrators often test media converters and other network equipment,  to ensure the equipment functions properly, before installing them at the end customer’s site.  Having invested in bench test equipment, integrators and installers  test the media converters for valid link and passing data.  If the equipment is not linking/passing data, it’s a lot easier to troubleshoot  in a lab. Generally, when new equipment is tested, 85% of the time problems occur due to a mismatch of speed, duplex, protocol, or fiber type. Susan Stanley | 5/13/2014 3:18:38 PM | 7 comments

Fiber Optics in Networks

Fiber optics is commonly used to connect network equipment between endpoints. Unlike copper, which covers no more than 100m, fiber can support up to 130Km of distance between endpoints. Some of the attributes of fiber are:  immunity from EMI, security (hack-proof, unlike copper) for transmission of data, wide bandwidth (up to 10G), and in the case of fiber optic transceivers for network equipment, Class I, Eye-safe laser certification.

Weather Impact on Fiber Optics

This first week of January, 2014 has shown how record-breaking cold temperatures affect people, equipment, schedules and life in general. The fans at the Green Bay NFL game defied odds by sitting through 4 quarters of exceptional cold temperatures.

OSI Layers 1 and 2

In the world of networking, the OSI layers are the foundation on which the networks are built. But what exactly are the OSI layers? And how do they impact the devices that interconnect to make a network happen?

The Importance of Updating Software and Firmware for Managed Network Equipment

Simple Network Management Protocol (SNMP) is a beautiful thing…..when it functions properly. An SNMP application can be supported by a Graphical User Interface (GUI), and displayed via a desktop, web browser-based or web server-based software. The software is often fee-based, and provides critical information to the network administrator. Critical information such as whether a linked interface is active or dead, if one of two power supplies has died, whether the speed has dropped from gigabit to 100Mbps, for example. All these conditions cause the network administrator a lot of heartburn, and antacids are just not going to help. Susan Stanley | 10/15/2013 2:49:23 PM | 1 comments

NEBS, UL/FCC and Network Equipment

The convergence of equipment installed in Ethernet networks and Telecoms has often presented expectations and subsequent issues regarding the standards and certifications the equipment meets. For years, Ethernet equipment was, and continues to be, designed to meet standards based on certifications of UL (Underwriters Labs) and FCC Federal Communications Commission). On the other hand, the Telecom industry expects product designs based on the NEBS standard (Network Equipment-Building System). BBAdmin | 8/20/2013 12:59:28 PM | 1 comments

Classifications of Fiber & Safety

Fiber Optic lasers fall into classifications based on the specifications by the IEC 60825-1 standard. The old standard was based on Roman numerals (I-IV) in the US and Arabic numerals (1-4) in the EU. Today the revised system uses Arabic numerals in all jurisdictions.

The Summer of Fiber, Part III

In our next installation of The Summer of Fiber, we cover what XFP is all about. The small form-factor pluggable, XFP, is a compact, hot-pluggable transceiver used for the typical applications such as data centers, enterprise wiring closets and service provider transport applications.

The Summer of Fiber, Part II

The small form-factor pluggable (SFP+) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. SFP+ supports 10G, cannot support lower rates of speed, and is in compliance with the protocol of IEEE802.3ae, SFF-8431, SFF-8432; whereas the SFP and XFP fall under the MSA agreement (Multi-Source Agreement).

Misconceptions about MTBF

“Mean time between failures (MTBF) is an important element when considering the purchase of any product. This is particularly true with network equipment, as reliability is very important. Many companies have to quantify the performance and longevity of a product as part of the bid process,” says Susan Stanley, Senior Technical Support Engineer Susan Stanley | 2/20/2011 12:05:15 PM | 0 comments
