G.709 ODU Maintenance Signals

-
  ODU maintenance signals  Three ODU maintenance signals are defined as per G.709: ODU-AIS, ODU-OCI and ODU-LCK ODU alarm indication signal (ODU-AIS)   ODUK-AIS-PM is a secondary condition that indicates a more serious condition such as the LOS (OCN/STMN) alarm occurring downstream. The ODUK-AIS-PM condition is reported in the path monitoring area of the optical data unit wrapper overhead. ODUK-AIS-PM is caused by the upstream ODUK-OCI-PM .   ODUk-AIS is specified as all "1"s in the entire ODU signal, excluding the frame alignment overhead (FA OH), OTU overhead (OTU OH)  The ODUk contains one instance of ODU AIS. The ODUCn contains n instances of ODU AIS, numbered 1 to n (ODU AIS #1 to #n). In addition, the ODU-AIS s...

OPEN ROADM MSA

The goals of the Open ROADM Multi-Source Agreement are  (1) the disaggregation and opening up of traditionally proprietary ROADM systems   (2) the SDN-enablement of traditionally fixed ROADMs   There are many ways to disaggregate ROADM systems, e.g. hardware disaggregation (e.g. defining a common shelf) or functional disaggregation (less about hardware, more about function). Due to the complexity of common shelves, the Open ROADM MSA chose the functional disaggregation first. We defined three optical functions: pluggable optics, transponder and ROADM (the optical switch part with amplifiers, couplers, WSS, etc.). Common shelves can be introduced at a later point for some functions, like transponders, if they make sense as an extension of the models.   All of the three disaggregated functions (pluggable optics, transponder and ROADM) are controllable through an open standards-based API (written in the data modeling language YANG) that can be accessed through a...

CFP2 DCO block diagram-by OIF(IA)

Image
  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 suppli...
