TDR - TDR (time-domain-reflectometry) and transmission measurements. A TDR oscilloscope and TDR-based software-modeling tools become a powerful system for interconnect-impedance measurements, signal-integrity Spice and IBIS modeling, and prelayout and field-solver model validation. System Integrity with TDR measurements.

Temperature Rating - Maximum temperature at which a material may be used in continuous operation safely.

Temper - Measurement of the degree of hardness or strength of a metal.

Terminal - A part of a component which provides a reusable connection.

Terminal Block - An assembly of terminals in a housing or body of insulating material to facilitate interconnection between multiple conductors. Also called terminal strip or barrier blocks if the terminals are separated by an insulation barrier. Terminal Block Overview and Catalog

Threaded Coupling - Method for coupling mating connectors that engages threads in a coupling ring with threads on a receptacle shell.

Throughput - Ethernet Throughput is a measurement similar to utilization. Throughput, however, measures the number of packets sent versus the number of packets received. It is very much a quality of service metric. If 100 packets are sent and 90 of them arrive at the far end, then the throughput of the system is 90%.

TIA/EIA 568-A and T568-B - The pins on the RJ45 plug are numbered 1 to 8. If you are holding a CAT 5 patch cable in your hand, as if inserting into a jack, with the contacts facing in the up position, pin 1 will be on the far left. Pin 8 will be the pin on the far right. This is the orientation used when defining the wiring assignments in the RJ45 plug

TIA-1096-A - The technical requirements outlined in ANSI/TIA-1096-A specify physical dimensions, mechanical
characteristics, and contact requirements for:

1. Carrier-installed jacks used at the demarcation point in accordance with 47 CFR 68.105(a);
2. Plugs and jacks used with inside wiring in accordance with 47 CFR 68.213(b); and
3. Plugs and jacks used to connect terminal equipment to wireline carrier networks in accordance with ANSI/TIA- 968-B. TIA-1096-A Information.

TIA-1096-A Declaration of Conformity - The Declaration of Conformity for ANSI/TIA-1096-A. Declaration for XRJS Connector Series. Please contact Xmultiple Technical Support for Declarations for other product series.

Tight Buffer - Material used to secure a fiber in place within a fiber optic cable.

Tinning - Process used to coat iron or steel terminals with tin to improve soldering and protect against rust.

Tin-Based Plating for Lead-Free Products - Using Tin-Based plating is a customers requirement for improving their assembly of our products to their PCB. Xmultipleˇ¦s use of tin alloys on the solderable termination is based on the materialˇ¦s excellent properties of solderability and resistance to corrosion. Tin-Based Plating Statement.

Tin Whiskers - Tin deposits which form on a printed circuit board. Tin whiskers can occur when ˇ§pureˇ¨ tin plating is used on connectors. This ia rare for this condition to occur. Tin Whiskers Application Note.

Total Internal Reflection - Light rays reflected at the core-clad boundary of an optical fiber, allowing transmission along the length of the fiber.

Transceiver - Combination device that acts as both a transmitter and a receiver.

Transformer - Transformers are a passive device which transforms alternative (AC) electrical energy from one circuit into another through electonmagnetic induciton. In general, transformers transfer all energy instantaneously form one winding to another while storing no or little energy in the process.

Transmission - Transfer of electric energy by use of conductors, radiation or induction fields.Transformer and inductors are important parts of any power supply circuit design.

Triaxial - Cable with 3 concentric conductors.

Tubing - Extruded non-supported material.A device that contains more than one locator that can be indexed by rotating a circular barrel, and when attached to a crimping tool, positions the contact.

Turret Head - A device that contains more than one locator that can be indexed by rotating a circular barrel. Once attached to a crimping tool it positions the contact.

Twinaxial Cable - Twinaxial cabling, or "Twinax", is a type of cable similar to coaxial cable, but with two inner conductors instead of one. Due to cost efficiency it is becoming common in modern (2013) very-short-range high-speed differential signaling applications.

Twisted Pair - Pair of wires twisted together, most often used for low-speed communication wire cables.


UCC - The Uniform Commercial Code (UCC or the Code), first published in 1952, is one of a number of uniform acts that have been promulgated in conjunction with efforts to harmonize the law of sales and other commercial transactions in all 50 states within the United States of Americ

UG - Standard abbreviation for Universal Government; precedes the number on coaxial cable connectors.

UL - Underwriters Laboratories, Inc. safety standards mark. (UL) is one of the world's leading providers of product safety and certification testing services, performing more than 90,000 evaluations each year. Products that successfully navigate through its stringent tests are registered with the lab and can bear the UL Mark - a widely trusted symbol for product safety and assurance. Xmultiple UL Documents.

Ultrajax - Dual RJ45 Connectors which are emerging for high density Connectors and Cable Devices An RJ Style connector which expands the port count of this connectivity and results in a space savings. In addition, one version of the UltraJAX are designed for harsh environments. RJ11 and RJ45 Connectors functionality can be combined into on UltraJAX connector.

Ultraviolet - Range of electromagnetic waves in the non-visible spectrum, with wavelengths from 10 to 400 nm (shorter than visible light).

UG Symbol - Used to indicate a connector made to US government spec.

USB - Acronym for Universal Serial Bus ˇV Was designed to standardize hardware interface connection computer peripherals such as the MP3 player, iPod, iPhone, iPad, keyboard, mouse, joystick, scanner, printer, telephony devices and any device with a USB port or connector. There 3 USB standards, USB 1.1, USB 2.0 and USB 3.0. USB 1.1 can transfer data speed up to 1.5 Mbit/s (low-bandwidth) and 12 Mbit/s (full-bandwidth), USB 2.0 also called Hi-Speed can transfer rate up to 480 Mbit/s (60MB/s) and USB 3.0 has a blazing transmission speed up to 5 Gbit/s which is 10 times faster USB 2.0.

USB Type-C Connectors - USB Type-C Overview. The Type-C is the next generation of USB connectors and cables which will be easier to use and able to push more data faster. USB connectors have become the connector of choice for some manufacturers of smartphones, tablets and other mobile devices.

USB Power Delivery - from a data interface capable of supplying limited power to a primary provider of power with a data interface.
