Racks & Cables

Network Server Cabinets
Network Racks are manufactured for applications that requires large no. of network equipment’s like hub, switches, routers & bundles of cable s to cascade down either side or both sides of rack rails and still maintain the security and manageability.
The vertical rack rails are mounted on a channel that allows them to slide left to right and front to back . Our design facilitates 4”-6’extra space for bulk cabling , which is good for SUN & Cisco switches that have bulk cables coming of the the front toward one or both sides.
With Information Technology gaining prominence across all walks of business, reliable Network infrastructure has become a critical issue for all organizations. Large businesses like Banking and Finance, FMCG Companies, Pharmaceutical companies, Manufacturing Facilities and Distribution networks depend largely on their Local and Wide Area Networks to achieve global competitiveness and supreme operational efficiency.
In networking racks we offer following :
Network Cables
Anyone who has plugged their computer into a broadband Internet connection such as cable or DSL has used an Ethernet cable. Ethernet cables are the standard cables commonly used to connect a modem to a router, and, likewise, to connect a router to a computer’s network interface card (NIC). These thick, flexible cables are all practically indistinguishable to the untrained eye, but not all Ethernet cables are the same.
The Major Categories of Ethernet Cables
Ethernet cables have been evolving since the beginning of the Ethernet standard in 1985. Many different categories of Ethernet cable have been developed, and each category has different specifications as far as shielding from electromagnetic interference, data transmission speed, and the possible bandwidth frequency range required to achieve that speed. It is understandable that some confusion can arise when looking at all the available options for Ethernet cabling. Luckily, the category of cable is usually clearly printed on the cable’s sheath, so there can be no doubt as to the type of cable being used. There are also certain types of cables recognized as common industry standards. This guide will describe a few of the most common categories of Ethernet cable that are used in modern networks.
Category 3
Category 3 Ethernet cable, also known as Cat 3 or station wire, is one of the oldest forms of Ethernet cable still in use today. It is an unshielded twisted pair (UTP) cable that is capable of carrying 10 megabits per second (Mbps) of data or voice transmissions. Its maximum possible bandwidth is 16 MHz. Cat 3 cable reached the peak of its popularity in the early 1990s, as it was then the industry standard for computer networks.
With the debut of the faster Category 5 cable, however, Cat 3 fell out of favor. It still can be seen in use in two-line telephone systems and older 10BASE-T Ethernet installations.
Category 5
Category 5 (Cat 5) Ethernet cable is the successor to the earlier Category 3. Like Cat 3, it is a UTP cable, but it is able to carry data at a higher transfer rate. Cat 5 cables introduced the 10/100Mbps speed to the Ethernet, which means that the cables can support either 10 Mbps or 100 Mbps speeds. A 100 Mbps speed is also known as Fast Ethernet, and Cat 5 cables were the first Fast Ethernet-capable cables to be introduced. They also can be used for telephone signals and video, in addition to Ethernet data. This category has been superseded by the newer Category 5e cables.
Category 5e
The Category 5e standard is an enhanced version of Cat 5 cable, which is optimized to reduce crosstalk, or the unwanted transmission of signals between data channels. This category works for 10/100 Mbps and 1000 Mbps (Gigabit) Ethernet, and it has become the most widely used category of Ethernet cable available on the market. While Cat 5 is common in existing installations, Cat 5e has completely replaced it in new installations. While both Cat 5 and Cat 5e cables contain four twisted pairs of wires, Cat 5 only utilizes two of these pairs for Fast Ethernet, while Cat 5e uses all four, enabling Gigabit Ethernet speeds. Bandwidth is also increased with Cat 5e cables, which can support a maximum bandwidth of 100 MHz. Cat 5e cables are backward compatible with Cat 5 cables, and can be used in any modern network installation.
Category 6
One of the major differences between Category 5e and the newer Category 6 is in transmission performance. While Cat 5e cables can handle Gigabit Ethernet speeds, Cat 6 cables are certified to handle Gigabit Ethernet with a bandwidth of up to 250 MHz. Cat 6 cables have several improvements, including better insulation and thinner wires, that provide a higher signal-to-noise ratio, and are better suited for environments in which there may be higher electromagnetic interference. Some Cat 6 cables are available in shielded twisted pair (STP) forms or UTP forms. However, for most applications, Cat 5e cable is adequate for gigabit Ethernet, and it is much less expensive than Cat 6 cable. Cat 6 cable is also backwards compatible with Cat 5 and 5e cables.
Category 6a
Category 6 a cable, or augmented Category 6 cable, improves upon the basic Cat 6 cable by allowing 10,000 Mbps data transmission rates and effectively doubling the maximum bandwidth to 500 MHz. Category 6a cables are usually available in STP form, and, as a result, must have specialized connectors that ground the cable.
Category 7
Category 7 cable, also known as Class F, is a fully shielded cable that supports speeds of up to 10 Gbps (10,000 Mbps) and bandwidths of up to 600 Mhz. Cat 7 cables consist of a screened, shielded twisted pair (SSTP) of wires, and the layers of insulation and shielding contained within them are even more extensive than that of Cat 6 cables. Because of this shielding, they are thicker, more bulky, and more difficult to bend. Additionally, each of the shielding layers must be grounded, or else performance may be reduced to the point that there will be no improvement over Cat 6, and performance may be worse than Cat 5. For this reason, it’s very important to understand the type of connectors at the ends of a Cat 7 cable.
The following table summarizes the most common types of Ethernet cables, including their maximum data transmission speeds and maximum bandwidths.
Category Cable Type Maximum Data Transmission Speed Maximum Bandwidth
Category 3 UTP 10 Mbps 16 MHz
Category 5 UTP 10/100 Mbps 100 MHz
Category 5 e UTP 1000 Mbps 100 MHz
Category 6 UTP or STP 1000 Mbps 250 MHz
Category 6 a STP 10,000 Mbps 500 MHz
Category 7 SSTP 10,000 Mbps 600 MHz
