• Support failed software upgrades, partial card upgrades, controller synchronization issues and rollback activities.
• Review and validate MOPs, pre-checks, post-checks, rollback plans and maintenance-window readiness.
• Open and manage technical cases with Ciena, Nokia, Infinera, ADVA/Adtran, Cisco or other OEM TAC teams.
• Provide complete logs, topology details, impact analysis and troubleshooting evidence to OEMs.
• Track vendor TAC cases until a permanent resolution, patch, workaround or hardware replacement is delivered.
• Support testing and validation of vendor-recommended fixes before implementation in the production network.
• Maintain a knowledge base of known defects, workarounds, upgrade recommendations and recurring platform issues.

• DWDM, CWDM, OTN, SDH and SONET
• ROADM, WSS, EDFA/Raman amplification
• Transponders, muxponders and optical line systems
• OTU/ODU mapping and Carrier Ethernet services
• Optical power, span loss, OSNR, BER, FEC and Q-factor
• Protection mechanisms such as 1+1, SNCP/MSP and OTN/ROADM protection
