Black Box Explains...The MPO connector.

MPO stands for multifiber push-on connector. It is a connector for multifiber ribbon cable that generally contains 6, 8, 12, or 24 fibers. It is defined by IEC-61754-7 and TIA-604-5-D,... more/see it nowalso known as FOCIS 5. The MPO connector, combined with lightweight ribbon cable, represents a huge technological advance over traditional multifiber cables. It’s lighter, more compact, easier to install, and less expensive.

A single MPO connector replaces up to 12, 24, or 36 standard connectors. This very high density means lower space requirements and reduced costs for your installation. Traditional, tight-buffered multifiber cable needs to have each fiber individually terminated by a skilled technician. But MPO fiber optic cable, which carries multiple fibers, comes preterminated. Just plug it in and you’re ready to go.

MPO connectors feature an intuitive push-pull latching sleeve mechanism with an audible click upon connection and are easy to use. The MPO connector is similar to the MT-RJ connector. The MPO’s ferrule surface of 2.45 x 6.40 mm is slightly bigger than the MT-RJ’s, and the latching mechanism works with a sliding sleeve latch rather than a push-in latch.

The MPO connector can be either male or female. You can tell the male connector by the two alignment pins protruding from the end of the ferrule. The MPO ferrule is generally flat for multimode applications and angled for single-mode applications.

MPO connectors are also commonly called MTP® connectors, which is a registered trademark of US Conec. The MTP connector is an MPO connector engineered with particular enhancements to improve optical and mechanical performance. The two connectors are compatible. collapse

Black Box Explains...Digital Visual Interface (DVI) connectors.

DVI (Digital Video Interface) is the standard digital interface for transmitting uncompressed high-definition, 1080p video between PCs and monitors and other computer equipment. Because DVI accommodates both analog and digital... more/see it nowinterfaces with a single connector, it is also compatible with the VGA interface. DVI differs from HDMI in that HDMI is more commonly found on HDTVs and consumer electronics.

The DVI standard is based on transition-minimized differential signaling (TMDS). There are two DVI formats: Single-Link and Dual-Link. Single-link cables use one TMDS-165 MHz transmitter and dual-link cables use two. The dual-link cables double the power of the transmission. A single-link cable can transmit a resolution ?of 1920 x 1200 vs. 2560 x 1600 for a dual-link cable.

There are several types of connectors: DVI-D, DVI-I, DVI-A, DFP, and EVC.

DVI-D (digital). This digital-only interface provides a high-quality image and fast transfer rates between a digital video source and monitors. It eliminates analog conversion and improves the display. It can be used when one or both connections are DVI-D.

DVI-I (integrated). This interface supports both digital and analog RGB connections. It can transmit either a digital-to-digital signal or an analog-to-analog signal. It can be used with adapters to enable connectivity to a VGA or DVI-I display or digital connectivity to a DVI-D display. If both connectors are DVI-I, you can use any DVI cable, but DVI-I is recommended.

DVI-A (analog) This interface is used to carry a DVI signal from a computer to an analog VGA device, such as a display. If one connection is DVI and the other is VGA HD15, you need a cable or adapter with both connectors.

DFP (Digital Flat Panel) was an early digital-only connector used on some displays.

EVC (also known as P&D, for Plug & Display), another older connector, handles digital and analog connections.

Black Box Explains... Speaker wire gauge.

Wire gauge (often shown as AWG, for American Wire Gauge) is a measure of the thickness of the wire. The more a wire is drawn or sized, the smaller its... more/see it nowdiameter will be. The lower the wire gauge, the thicker the wire.

For example, a 24 AWG wire is thinner than a 14 AWG wire. A lower AWG means longer transmission distance and better integrity. As a rule of thumb, power loss decreases as the wire size increases.

When it comes to choosing speaker cable, consider a few factors: distance, the type of system and amplifier you have, the frequencies of the signals being handled, and any specifications that the speaker manufacturer recommends.

For most home applications where you simply need to run cable from your stereo to speakers in the same room—or even behind the walls to other rooms—16 AWG cable is usually fine.

If you’re considering runs of more than 40 feet (12.1 m), consider using 14 AWG or even 12 AWG cable. They both offer better transmission and less resistance over longer distances. You should probably choose 12 AWG cable for high-end audio systems with higher power output or for low-frequency subwoofers. As a rule of thumb, power loss decreases as the wire size increases.

To terminate your cable, choose gold connectors. Because gold resists oxidation over time, gold connectors wear better and offer better peformance than other connectors do. collapse
