VSC7112XJW is a type of transceiver that works as either an Ethernet to Serial Converter, V.35 Link Controller, or Digital Data Interface (DDI). This transceiver has been used in various telecom application fields, primarily in the optical transport arena where it converts the digital data to electrical signals and vice versa.

This transceiver is widely used in various telecom application fields primarily in the optical transport arena. They are primarily used for the transmission of Serial-based data streams of the various protocols. These protocol streams are transformed and converted back and forth in VSC7112XJW.

Working Principle

The working principle of VSC7112XJW is based on the conversion of optical signals into electrical signals and vice versa. The transmission device uses multiple LEDs (light-emitting diodes) at its input side to transmit the signal in accordance to the medium-level protocols, as well as its different modulation used. On its output side, either an Amplifier is used to transfer signals or a photodetector increases the sensitivity of the receiver. The eye pattern of the receiver is usually placed side-by-side to the transmitter, which is activated successively.

The transmitting side (Tx) is the process of converting base-band signals such as 10 Mbps Ethernet packets into an optical signal. Here, the information from the Ethernet is encoded with a line coding scheme (like Manchester or 8B10B) and this signal is combined with the carrier frequency. The resulting signal is then passed through the laser diode for transmission. The receiver (Rx) side performs the reverse function of decoding the received optical signal and restoring it to base-band form.

This transceiver is also capable of carrying out bidirectional transmissions. This is achieved through the use of an opto-coupler, which is placed beside the laser diode. This coupler is used to draw the optical signal transmitted from one source and carrying it to the other. This device also allows the communication of two separate transmission systems to take place simultaneously in the bi-directional mode.

VSC7112XJW transceivers are used to transmit and receive data streams on a telecom network. This transceiver is designed to handle both analog and digital signals effectively, in order to provide reliable, fast and secure communication between connected systems.

VSC7112XJW transceivers maintain the quality of their data streams by using error correction algorithms like Reed-Solomon coding and Viterbi coding, which provides reliable error-free data transmission. In addition, these transceivers also provide a wide range of features such as link aggregation, congestion control, rate and latency monitoring and bit-error-rate (BER) testing.
