Module Knowledge

The compatibility of the fiber optic transceiver module is very important because it may causes your device fault. In some cases, due to environmental parameters beyond the data sheet or standard, it will cause the module performance degradation, thereby

Digital optical monitoring (DOM) is a feature which allows you to monitor many parameters of the transceiver module in real-time.

This is extensively used to refer to modular connectors with Ethernet-type wiring pin outs, these take the form of 8 position 8 contact, and so are more accurately known as 8P8C connectors. In relation to transceiver modules this type of connector is most

From the principle, composition and the division to know the SFP module

DDM is Digital-diagnostic-monitoring (this feature is also known as digital optical monitoring (DOM)) which provides a user with critical information concerning the status of the transmitted and received signals. This approach allows for better fault isol

Some digital data streams, especially high-speed serial data streams (such as the raw stream of data from the magnetic head of a disk drive) are sent without an accompanying clock signal. The receiver generates a clock from an approximate frequency refere

Fiber optic transceivers include both a transmitter and a receiver in the same component.

In telecommunication transmission, the bit error rate (BER) is the percentage of bits that have errors relative to the total number of bits received in a transmission, usually expressed as ten to a negative power.

How to calculate power budget? You can make a rough estimate of a link power budget. For this, you must allow 0.75 dB for each fiber-to-fiber connection, and assume that fiber loss is proportional with length in the fiber.

Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled "visible light". This "visible light" corresponds to a wavelength range of 400 - 700 nanometers (nm) and a color range of violet

An optical transceiver chip is an integrated circuit (IC) that transmits and receives data using optical fiber rather than electrical wire. Optical fiber, also called fiber optic, refers to the technology associated with the transfer of information in lig

Insertion loss for a connector or splice is the difference in power that you see when you insert the device into the system.

A fiber-optic transceiver is a accessory acclimated to forward and accept optical information. There are a amount of altered apparatus on one of these devices, including a ablaze antecedent and an electrical component. The transceiver has two ends, one th

Fiber optic transmission systems (datalinks) all work similar to the diagram shown above. They consist of a transmitter on one end of a fiber and a receiver on the other end. Most systems operate by transmitting in one direction on one fiber and in the re

Receivers use semiconductor detectors (photodiodes or photodetectors) to convert optical signals to electrical signals. Silicon photodiodes are used for short wavelength links (650 for POF and 850 for glass MM fiber). Long wavelength systems usually use I

Simply speaking, simplex communication refers to communication that occurs in one direction only.

In order to measure optical loss, you can use two units, namely, dBm and dB. While dBm is the actual power level represented in milliwatts, dB (decibel) is the difference between the powers.

Full-Duplex is like the ordinary two-lane highway. In some cases, where traffic is heavy enough, a railroad will decide to lay a double track to allow trains to pass in both directions.

In telecommunications, extinction ratio (re) is the ratio of two optical power levels of a digital signal generated by an optical source, e.g., a laser diode.

This page shows you the knowledge of Jitter. A certain amount of jitter will appear at the output port of any network element (NE), even with an entirely jitter-free digital or clock signal applied to the input, effect known as jitter generation...
