Irig fiber converter

Since the transponders are external to the switches, they do not void the warranty or service contract from the switch manufacturer. For distribution of multiple single-mode fiber runs from a multi-mode switch, xFF Transponder chassis plug-in modules can be installed in a high-density iConverter Module Chassis.

Mode conversion is typically required when: Multimode equipment is in a building and connectivity is required to an outside plant single-mode network Legacy equipment uses multimode fixed fiber LC and SC ports, and connectivity is required to single-mode equipment High cost of proprietary Single-mode SFPs Connecting multimode network equipment to a single-mode CWDM multiplexer.

Multimode to Single-Mode Convert Multimode to Single-mode Fiber In this application example, a network requires multimode to single-mode fiber conversion to connect two in-building multimode networks over a single-mode fiber link, which supports longer distances than multimode fiber.

The table below shows some examples for the assignments of the 3rd digit. IEEE C The raw time code is a continuous stream of binary data transmitted at a given rate. Optionally this binary data stream can be modulated onto a sine wave carrier of a particular frequency. The image below shows both types of signal, the unmodulated signal in the upper area, and the modulated signal in the lower area:.

Due to its nature as digital signals the DCLS time codes have well-defined slopes. Also, the propagation delays of digital line drivers and receivers are usually pretty constant, so it is easy to generate an accurate trigger signal from a DCLS slope and thus yield a high accuracy from a received DCLS time code.

For modulated signals the exact start of a signal frame is bound to the zero-crossing of the carrier signal , i. On the receiver side it requires much more effort to detect the exact zero crossing point of a modulated sine-wave signal than capturing a digital slope. Also, modulated time codes often use filters, transformers, automatic gain control AGC circuits, etc. It also requires some effort to compensate such signal delays and yield an accuracy and precision from a modulated time code signal which is in the same range as the accuracy and precision of a DCLS signal.

For Meinberg devices the difference is usually a few microseconds. On the other hand, it's easier to distribute a modulated signal than a DCLS signal.

A single modulated signal output can usually drive the inputs of several time code receivers by just using coaxial cabling and T-connectors. Also, time codes modulated onto a tone frequency carrier signal can easily be transmitted over a telephone line, can be recorded on magnetic tape, etc.

Such connections are usually point-to-point only, i. Wiring 1 output signal to e. The proper solution to distribute DCLS signals is to use a kind of diplexer appropriate for the particular physical signal, which increases the overall effort and costs. In the text of the originally published standards the pieces of data included in the transmitted signal are called Coded Expressions. Some coded expressions are included in all time code formats, while other coded expressions are only provided by certain code formats.

It includes the day-of-year as well as the hours, minutes, and seconds of that day, and in fact this is the only time information provided by some code formats. See Choosing A Code Format for more information. The optional SBS field SBS contains the second of the day, which can also easily be computed from the hours, minutes, and seconds in the TOY field, so this is some redundant information.

The year number is very helful to determine if the current year is a leap year, or not, and hence if February 29 has to be accounted for when converting the transmitted TOY to a calendar date, or not. So when choosing a code format for an application a code format providing a year number should be used preferably.

The Control Field CF refers to a set of data bits in a code frame which isn't otherwise used for specific data. If the CF is supported then the meaning of each bit transmitted in this bit field is always application defined. This means, a particular time code generator could put some specific information into those bits which is useful for a specific application, and a specific receiver can extract those bits and interpret the CF bits according to what has been specified for this application, without affecting the transported time.

If the CF is not supported by the code format, or simply not used by the generator, then all of these bits in the code frame are simply 0.
