CFP2 DCO block diagram-by OIF(IA)

-

  Introduction:

The CFP2-DCO form factor of an optical transceiver which can support 100Gbit/s, 200Gbit/s, 300Gbit/s and/or 400Gbit/s line interface rates for Ethernet, ITU-T OTN, OIF and other applications. This specification is an extension to the CFP2 MSA MIS v2.6 (r06a) [2] and the CFP2 MSA Hardware Specification Rev. 1.0 [3] to support coherent applications in CFP2 form factor with a digital host interface.

 Functional Description: 

A functional block diagram of the CFP2-DCO is illustrated in Figure 1. Key module functions include transmitter optics, receiver optics, optical MUX/De-MUX in case of multi-carrier link, interface ICs, module controller supporting a MDIO/MDC management interface, and power conversion for a single +3.3V DC power supply from the host. The CFP2-DCO is a hot pluggable module form factor designed for optical networking applications.

 

 


The module electrical interface has been generically specified to allow for supplier-specific customization around various 4 × 25Gbit/s interfaces, but can also support potential interfaces such as 8× 25Gbit/s, 2 × 50Gbit/s, 4 × 50Gbit/s, 6 × 50Gb/s and 8 × 50Gbit/s

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 timing. Re-timing refers to CDR cl

What is Super C-band

  Super C band uses the ultra-wide C band (C120) in addition to the traditional C band (C80) and the extended C band (C96). It increases the available wavelength range. Super C band can transmit 120 wavelengths at a 50 GHz channel spacing and transmit 80 wavelengths at a 75 GHz channel spacing, greatly expanding the effective working spectrum compared with the traditional C band and extended C band. Therefore, it is called Super C band. Benefits of Super C Band - Improving the system transmission capacity When the transmission rate is the same and the channel spacing is 50 GHz, the Super C band supports a maximum of 120 wavelengths, while the traditional C band supports a maximum of 80 wavelengths. The Super C band increases the transmission capacity by 50%. Refere for more details: Huawei-Super C Band

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 .
