Using Pre-terminated Cat6 Cable For Signal Extension

图片
Thanks to the complexity of the fiber optic installation and audio video system, the need for sending multiple signal types and control over long distances has increasingly become intense. Ethernet cables like Cat 5e, Cat 6 and Cat 7, is an indispensable component for home or small business. Nowadays most manufacturers will recommend the use of solid shielded Cat 6 cable with shielded connectors other than using the HDBASE-T chipset for signal extension. This type of cable can be terminated in the field or purchased in specific lengths already terminated. The following article provides a brief introduction to the reasons why we should use Pre-terminated Cat 6 cables for the signal extension. Figure 1 shows the UTP Cat6 cables, Pre-terminated trunk cables, FS optical switches, cable manager wire duct. Brief Outlook: Cat 6 Over Cat5 Cable Cat5 and Cat6 copper Ethernet cables are the commonly used types for 1G/10G networks. So, what is the benefit of using Cat 6 cable instead of Cat 5? I…

How to Understand PoE and PoE+ Switches

图片
Power-over-Ethernet (PoE) is the technology that allows network switches to transmit power and data through an Ethernet cable at the same time. PoE switch streamlines both of the processes of powering and providing data to the device, which makes it a straightforward and reliable device for home network and small enterprise application. This article describes two types of PoE (PoE and PoE+) that are commonly used and provides information on what types of PoE can be used according to different applications. PoE Versus non-PoE Technology Power over Ethernet technology facilitates powering a device (such as an IP phone, IP Surveillance Camera, or NVR recorder) over the same Ethernet cable as the data traffic. Figure 1 shows an Ethernet Network with IP camera, PoE Switch, NVR recorder and Wireless router. Compared to non-PoE devices, PoE devices feature with flexibility that allow you to easily place endpoints anywhere in the business, even places where it might be difficult to run a powe…

What Are OM1, OM2, OM3 and OM4 Fiber Patch Cable?

图片
Fiber optic cable can be divided into several types. Usually we see single-mode and multimode fiber types available on the market. Multimode fibers are described by their core and cladding diameters. The diameter of the multi-mode fiber is either 50/125 µm or 62.5/125 µm. At present, there are four commonly used OM (multimode) fibers: OM1, OM2, OM3 and OM4. Each type of them has different characteristics. The picture above shows the development of OM multimode fibers. The Lime Green OM5 fibers are newly released and sure to be the mainstream transmission media in the near future. For more information about OM5 fibers, please turn to: OM5 Fiber Cable – Is It Worthwhile for 40G/100G SWDM4 Cabling Solution OM Multimode Fiber Standard Each “OM” has a minimum Modal Bandwidth (MBW) requirement. OM1, OM2, and OM3 are determined by the ISO 11801 standard, which is based on the modal bandwidth of the multi-mode fiber. In August of 2009, TIA/EIA approved and released 492AAAD, which defines the …

Why Third-party 40G QSFP+ Transceiver, Instead of OEM QSFP Module?

图片
For the data center or network upgrade, 40G network is a trending choice. Then where do you buy the 40G QSFP transceiver? Will you choose an OEM one or a third-party one? There are some differences between third-party 40G QSFP transceiver and OEM 40G QSFP transceiver, which will be shown below. Features of OEM 40G QSFP Transceiver Modules As we know, the OEM 40G QSFP transceiver from name brand like Cisco, Juniper and Brocade is widely used in data center and enterprise network. They all have some great features. The Cisco 40G QSFP transceiver offers a wide variety of high-density and low-power 40 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider applications. Here are some benefits of Cisco 40 Gbps transceiver: Hot-swappable input/output device that plugs into a 40 Gigabit Ethernet Cisco QSFP portFlexibility of interface choice (for different reach requirements and fiber types)Inter…

Introduction to Semiconductor Optical Amplifier (SOA)

图片
Optical amplifier, with the introduction in 1990s, conquered the regenerator technology and opened doors to the WDM technology. It is mainly used to amplify an optical signal directly, without the need to first convert it to an electrical signal. There are many types of optical amplifiers, namely Raman amplifiers, erbium doped-fiber amplifiers (EDFAs), and semiconductor optical amplifier (SOA). This article will make a clearer introduction to SOA amplifier, and analyze its advantages and disadvantages. The Basics of Semiconductor Optical Amplifier (SOA) SOA optical amplifiers use the semiconductor as the gain medium, which are designed to be used in general applications to increase optical launch power to compensate for loss of other optical devices. Semiconductor optical amplifiers are often adopted in telecommunication systems in the form of fiber-pigtailed components, operating at signal wavelengths between 0.85 µm and 1.6 µm and generating gains of up to 30 dB. Semiconductor optic…

Cisco Vs Huawei – Which One is the better Choice for Ethernet Switches?

图片
Cisco, as the big brother in the telecom industry, has dominated the market of networking devices (like routers and switches) for a long time. No one can compete with him. Huawei, however, is the rising star in Chinese market. It ranked 83rd in the latest Fortune 500 list on July 23, 2017. Many people assume that in the near future, Huawei will lead the world instead of Cisco. Thus, in this article, we are going to analyze the strength of Cisco and Huawei, along with the differences between Cisco and Huawei switches. Cisco Vs Huawei — Brand Awareness and Market Share Both Cisco and Huawei are the relatively young enterprises, which are founded in 1980s. With 30 years’ development, Cisco was at the top of respondent edge/core router and CES manufacturer leadership scores. Cisco systems mainly offers networking devices, networking management, Cisco IoS/NX-OS software, storage area networks, wireless equipment, data center devices, and interface & modules, etc. The above table shows …

Mikrotik Vs Ubiquiti – Which One is Better for Home Network?

图片
Ubiquiti Networks and Mikrotik were the rising stars in telecom field for the past year and a half, I have heard various fiber optic technicians telling me that Ubiquiti is better suited wireless applications while Mikrotik is excellent at what it does best—routers. As the cheap and reliable alternative to Cisco expensive equipment, Mikrotik has a learning curve not many can endure and Uniquiti, famous for its 1G/10G Unifi Switches, also has its limits. So, how to make a choice between them? This article will offer detailed information about Ubiquiti and Mikrotik in terms of target markets, price point as well as their pros and cons, from the perspective of a long-time Ubiquiti and Mikrotik user. Target Markets After looking around at their website, You must admit the Ubiquiti website is a bit better than the Mikrotik site. But, there is no way to say witch one is better? Each of them are making some unique products. Founded in 1996, MikroTik is a Latvian company aimed to develop rout…
