is spdif optical or coaxial?

They are both digital connections. Optical usually refers to the ADAT protocol over a fiber optic cable (TOSLINK), while SPDIF is usually transmitted over a coaxial "RCA" cable. "Usually", optical can carry 8 channels at 44.1/48KHz (or 4 at 88.2/96KHz in certain situations) while SPDIF is stereo (two channels).

Optical carries 8 channels at 44.1/48 kHz while SPDIF carries only 2 channels or is in stereo. It depends on the usage and the circumstance since SPDIF-enabled equipment will output SPDIF anyway if you don't need those extra channels.

It is the only condition. All the rest, resonator, iris, lenses, qswitching, mode-locking, gratings, prisms… it is there all for only purpose. To forse the light from the inverted population to be as homogene, as coherent as possible. (according to needs)… or to increase the output power.

You must have a very specific SPDIF digital cable. While a SPDIF coaxial connection looks like an RCA analog type connection, it is not the same. SPDIF is a stereo digital connection. RCA is a mono analog connection.

DC coupling allows you to see all signals from 0 Hz up to the max bandwidth of your scope. AC coupling filters out DC components. When you enable AC coupling on an oscilloscope channel, you're switching in a high-pass filter on the channel's input signal path. ... The AC coupling filter is an actual hardware filter.

Starting with AudioQuest Carbon coaxial and AudioQuest Vodka Toslink digital cables, the difference was primarily in clarity. That is, the sound was less transparent and softer with the Toslink cable, and soundstage depth was reduced compared with that of the coaxial cable.

Devices that emulate the 8255 protocol support two handshaking signals: Handshake Trigger—Also called Strobe Input (STB) and Acknowledge Input (ACK) Handshake Event—Also called Input Buffer Full (IBF) and Output Buffer Full (OBF)

The standard specifies multiple interconnection types with RCA coaxial cables and optical TOSLINK being two most popular. Commonly in audio manuals, it is commonly noted that the optical TOSLINK provides a superior connection due to the superior aspects of optical cables in general.

Single LNBF refers to an LNBF which looks at 1 Orbital Location and has 1 Coaxial Output. Dual LNBF refers to an LNBF which looks at 1 Orbital Location and has 2 Coaxial Outputs.

The SFP port is designed for use with small form factor (SFF) connectors, and offers high speed and physical compactness. It enables a Gigabit switch to allow optical or copper links by inserting the corresponding SFP module (fiber SFP or copper SFP).

A dioptre (British spelling) or diopter (American spelling) is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres. (1 dioptre = 1 m−1.) It is thus a unit of reciprocal length.

Today, coax is still widely used for RF applications, from “mini” sizes in two-way radios to rigid hardline and waveguides for high-power microwave transmitters. As a result, we have a tendency to think of coaxial cable being used primarily for single-channel applications.

The differences between the two connections are as follows: A Digital Optical connection uses a fiber optic cable. The digital audio bit stream is transmitted using pulses of light through this optical cable. A Digital Coaxial connection uses a cable that has RCA-type connectors.

The signal cabling selection is too often neglected by users, and it is important to understand that not all SDI cables are created equal, and each have their own targeted applications. ... The most common SDI format nowadays is 3G-SDI (2.97 Gbit/s), which can carry a full 1080P signal at 60Hz.

A cable with RCA connections can be used for SPDIF, audio, composite video and component video without any problems.

Three of the most commonly talked about cables through the decades are RCA cables, optical cables, and coaxial cables. ... Meanwhile, RCA cables are associated with analog signals. This is why optical cables offer superior sound quality and HDMI offers superior video and sound quality to RCA.

SDI is a professional video transmission interface, generally used in broadcast video equipment. SDI and HDMI both support uncompressed digital video transmission, but the HDMI interface to use the 19-line transmission, SDI with the ordinary 75-ohm coaxial line can.
