The Knowledge About Underground Wire Tracer


Why need the underground cable locator in our life. Because more and more underground cable as for the load was increased, their own aging and barbaric construction lead cable often fails is not the normal power supply, thus affecting the living and plant shutdowns, immeasurable loss is caused by the mining and other research units.Now an underground cable locator tester can help you to find the question cable.

FiberStore Underground Wire Tracer NF-816 can be used for testing different types of faults in cables like continuity, dislocation, open circuit, short circuit, cable pairing faults, or indications like shielding indication, straight cable/ cross over cable indication, etc. It can help us quickly to find the questions of the fiber optic cable.

About Underground Wire Locator:

The Underground Wire Tracer/Underground Cable Locator is designed to locate the path of non-energized wires behind walls and underground. The 816 is also capable of locating a specific circuit breaker, pinpointing wires before drilling and verifying dig sites underground. The effective range is up to 3 feet deep and up to 1000 feet in length.

Since its development, the unit consists of a transmitter, model 816T, is equipped with a thumb wheel switch for turning the unit on and adjusting the output level on the front of the unit for use with the large alligator clip leads. Push the switch to select to test”Cable Scan” or”Battery Test” The transmitter is constructed of high impact plastic and is powered by one 9V battery.

The receiver, model 816R, is equipped with a thumb wheel switch for turning the unit on and adjusting the receiver gain. The tracking antenna is attached to the receiver with a 3-foot long cable(such as Cat 7 patch cable). Also is equipped with a White LED light and a external earphone, The receiver has been designed to filter AC power related noise. The receiver is constructed of high impact plastic and is powered by one 9V battery.

The alligator clip leads are available to connect the transmitter to electrical wire, CATV coax, telephone drops, irrigation control wires or metallic pipes.

This locating system is packaged in a toolkit & box with extra batteries, external earphone and has operating instructions in the behind of the toolkit.

Everything You Should Know About Cat7 Patch Cable


Network Cable increasingly welcomed by the people. However, the rapid development of network applications increasing demand for bandwidth. As technology continues to progress, here comes a higher level of Cat7 patch cable to meet most commercial applications.

Cat7 Patch Cable Definition

Cat7 patch cable is referred to as Category 7 patch cable, Cat7 network cabling is used as a cabling infrastructure for 1000BASE-T (Gigabit Ethernet, or GbE) and 10GBASE-T (10-Gigabit Ethernet, or 10 GbE) networks.  The Cat7 standard provides performance of up to 600 MHz and can be used up to a maximum length of 100 meters.

Cat7 patch cable

Category 7 cable is able to achieve higher performance than preceding Ethernet standards such as Cat5, Cat5e and Cat6 by requiring each of its twisted wire pairs to be fully shielded.  This is known as Screen Shielded Twisted Pair (SSTP) or Screened Foiled Twisted Pair (SFTP) wiring, and it almost completely eliminates alien crosstalk while significantly improving noise resistance.

The Cat7 standard was published in 2002 by the International Organization for Standardization (ISO) and is also known as Class F cabling.  While more expensive than Cat 5e and Cat 6 cabling, Cat 7 cabling does have a 15-year lifecycle (compared to estimated 10-year lifecycles for Cat5e and Cat6), which helps improve its overall return on investment (ROI).

Cat 7 cable was developed with strict specifications on crosstalk and EMI protection. Cat 7 cable features four individually shielded pairs as well as an overall cable shield to protect the signals from crosstalk and EMI. Cat7 cable provides a copper solution for 10-Gigabit Ethernet at 100 meters.

Category 7 and fiber connectorCat7 cable is commonly terminated using a GG45 connector, which is a connector that it backwards compatible with the 8p8c RJ45 connectors used on Cat6 or Cat5e cable. The GG45 connector has four additional conductors that provide support for frequencies of up to 600MHz. The higher frequencies allow Cat7 patch cable to support 10-Gigabit Ethernet. Cat7 cable may also be terminated using TERA connectors, which were developed by Siemon™. The TERA connector has a unique footprint and is not compatible with a standard 8p8c (RJ45) connector. The TERA connector is also capable of supporting frequencies of up to 600MHz. The ability to support the higher frequencies allows Cat7 patch cable to carry more data. This allows Cat 7 patch cable to support Ethernet applications up to 10-Gigabit Ethernet.

What is the application for a data center?

Cat7 cabling will be used for backbone connections between servers within a data center. This provides a high-speed  interconnect used for data transfer within the network.

Does this replace fiber?
This provides an alternative to using fiber optic cabling within the data center. Cat7 cabling will provide similar performance to some fiber solutions. The cost of equipment that supports copper cabling is typically less than equipment that supports fiber cabling. Another advantage is that the copper cabling is not as fragile as fiber cabling.

What’s the practical performance difference with Cat5e/6?
Cat7 patch cable is designed to support much higher frequency signals than Cat5e and Cat6.This allows Cat7 cabling to carry a larger amount of information. Cat7 cable is also able to better protect the signals traveling over the cable. The shielding as well as the tighter twists of the pairs in Cat7 cable lessens the effects of crosstalk and EMI.

Is Cat 7 widely used?
Currently, Cat7 Patch Cable is not widely adopted. Cat5e and Cat6 solutions sufficiently support the bandwidth requirements of today’s data centers, networks, and end users. Using Cat7 for a connection to a desktop would be unnecessary because the bandwidth would not be utilized. It may also be an unnecessary expense for many data center applications for the same reason. However, as technology advances and requirements increase, Cat7 cable will become more relevant in the data center and desktop connections.
