𝐖𝐡𝐚𝐭 𝐢𝐬 𝐢𝐫𝐨𝐚𝐝𝐦 𝐢𝐧 𝐖𝐃𝐌 𝐎𝐩𝐭𝐢𝐜𝐬 𝐚𝐧𝐝 𝐡𝐨𝐰 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬 iroadm is a single card in dwdm network used to give the function of multiple cards iroadm is concept by nokia and its an optical card to be installed in pss1830 iroadm consists of 2 WSSs ( wavelength selective switch ) 20 port each Of course it used MPO ports for high capacity In addition it contains EDFA amplifiers ingress and egress Contain also eVOA for power adjustment It has the ability for Optical channel monitoring It could filter the osc signal within 1510 nm It could also filter the OTDR test signal It holds osc sfp It supports wavekey detection for the power mangment purposes Support CDCF Max channels 96 with 50 G spacing The concept is founded also in other vendors like Huawei , INF ,… This concept of integrating multiple functions and blocks within single board reduces system complexity and space needed

Knowledge voice note : 1- protection in Telecom 2- microwave vs optical 3- protection vs restoration 4- pros and cons of protection and Restoration 5- GMPLS ASON

𝐒𝐮𝐦𝐦𝐚𝐫𝐲 𝐚𝐛𝐨𝐮𝐭 𝐏𝐫𝐨𝐭𝐞𝐜𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐑𝐞𝐬𝐭𝐨𝐫𝐚𝐭𝐢𝐨𝐧 𝐢𝐧 𝐖𝐃𝐌 𝐎𝐩𝐭𝐢𝐜𝐚𝐥 For Technical support , deployment , service configuration Engineers it’s important to keep the below info in mind : 1- wdm traffic is high capacity so protection is very important 2- protection is to assign dedicated resources as standby 3- restoration is to search for available resources upon failure without pre allocating resources in advance 4- sncp , olp , oms , och are different types of protection in Optical networks 5- y cable is one of the methods to protect client traffic 6- restoration is based on GMPLS ASON networks 7- protection switching time should be not more than 50 m sec 8- switching has 2 types ( unidirectional & bidirectional ) 9- switching modes can be revertive and non revertive 10- switching from main and standby could be triggered based on LOS alarm , power levels degradation , bit errors ( signal degraded ) and other alarms 11- you can lockout the protection , perform manuel switch , force switch , test the protection and release Question for you , if we locked out the protection and we got fiber cut at the working path , switching will be triggered or not ? Another question , what is WTR The photo Iam trying to show simple ring topology connecting some cities in Deutschland and a protection configured If interested to learn more about WDM in deep ( design , deployment , service provisioning , Testing , Troubleshooting ) hust ping me for questions , Training and Support
