What is CDR in Optical Modules

-
  What is CDR (Clock and Data Recovery) in Optical modules?   The full name of CDR is clock and data recovery, which can be simply understood as after the optical signal is converted into an electrical signal, the receiver performs electrical domain shaping and clock recovery.    CDR has two main functions 1. The first is to provide clock signal for each circuit of receiver;  2. The second is to judge the received signal, which is convenient for data signal recovery and subsequent processing.   Because when the optical signal is transmitted to a certain distance, it is usually long-distance transmission, and its waveform will appear a certain degree of distortion. The signals received by the receiver are pulse signals of different lengths. At this time, at the receiver, we can not get the data we need. Therefore, signal regeneration is needed at this time. Signal regeneration functions include re amplification, re shaping and re timin...

What is OpenZR+ for tranponder/muxponder

-
Image
Introduction OpenZR+ defines specifications for 1 00 - 400G single - wavelength optical ports for transceiver/transponder, muxceiver/ m uxponder ( TRXR/ TRPN , M U XR/M UXP ) node functions and for switch/router optical ports .   Open ZR+ Architecture   The architecture, shown in Figure 1 - 1 includes client sub - layers for up to four 100GBASE - R clients , up to two 200GBASE - R clients and a single 400GBASE - R client . Client data and alignment markers are extracted and re - timed to the line side clock domain using the general mapping protocol ( GMP ) . Retimed data plus GMP timing information is then mapped into one of the OpenZR+ frame formats . Those frames are multiplexed and OFEC encode d and become the payload of a DSP frame with DP - 16QAM, DP - 8QAM, or DP QPSK symbols .

Bit rate and Baud rate

-
In telecommunication Bit rate and baud rate are two important terms. Bit rate and baud rate play important role when we talk about Serial protocol  UART or modulation schemes like BPSK or QPSK   etc., Bit rate is the transmission of number of bits per second. It determines the number of bits traveled per second. Baud rate is defined as the number of signal units(also called as elements) per second. It determines how many times the state of a signal is changing.  For example baud rate is 9600 means 9600 signal level changes are happening within a second.It can determine how much bandwidth is required to send the signal. Relation between Bit rate(r), Baud rate(R), the number of bit per baud(n) Bit rate(r) = R x n Baud rate(R)= r/n
