The Skills You Bring (SDH/DWDM/CIN/CLOCK Focus)
3-10 years of experience in handling service outages and restoration within defined SLA timelines in transport networks. • Solid understanding of SDH and DWDM technologies, including multiple network architecture (Fixed line, CIN, XGS-PON) topology, and transmission concepts. • Hands-on experience in troubleshooting, configuration and provisioning of SDH (STM-1/4/16/64) and DWDM/OTN systems (Fault troubleshooting, wavelength provisioning, cross-connections, optical parameters). • Good knowledge of optical transport concepts such as:
Optical power levels and budgeting
OSNR, attenuation, dispersion
Protection schemes (MSP, SNCP, ring protection) • Experience in fault isolation and troubleshooting related to:
Fiber issues (cuts, degradation)
Hardware faults (cards, ports, transponders)
Performance degradation and service impact/outages • Comfortable in executing change requests as per defined MOPs, including circuit migrations, upgrades, and fault fixed under maintenance activities. • Ability to analyse recurring faults and implement preventive actions for network stability. • Familiarity with NMS/EMS tools for SDH/DWDM network monitoring, alarm handling and performance management. • Monitor and manage CIN and PON/XGS-PON network alarms and faults in a 24×7 operational environment. • Basic understanding of IP Routing & Switching/VLAN/VRF/BGP/MPLS/ERPS• Troubleshoot Layer 2 and Layer 3 service-related issues and restore services within SLA timelines.• Good understanding of telecom synchronization concepts and clocking architecture. • Good knowledge of telecom synchronization networks, timing distribution and with hands-on experience in
SyncE
IEEE 1588v2/PTP
NTP
GPS/GNSS timing systems
PRC/SSU synchronization networks• Exposure to Microwave transmission and ASON/OTN technologies is an added advantage. • Relevant OEM certifications (e.g., Ciena, Nokia, Cisco) or transport network certifications are a plus.
