Build-to-Order Layer 1 Systems Deliver in Weeks, Backed by Direct-to-Engineer US Support and Expedited Advance Replacement

REDMOND, Wash., Sept. 24, 2026 /PRNewswire/ — XKL LLC, a leading provider of Layer 1 optical networking systems, today announced a rapid-fulfillment delivery commitment for its MediaLight™ systems, paired with the launch of CoreAssure, an extended service solution engineered to eliminate operational friction and deployment delays. While some legacy telecom vendors quote hardware backlogs of anywhere from 20 to over 60 weeks, XKL delivers build-to-order DWDM systems in weeks, backed by direct access to senior optical engineers.

CoreAssure redefines optical transport support by eliminating offshored triage queues and multi-tier escalation delays. Combined with fast equipment turnaround, XKL provides complete operational velocity from deployment to Day-2 operations. 

Core Operational Advantages

• Rapid Hardware Delivery: Bypasses industry-wide supply chain bottlenecks with build-to-order fulfillment timelines measured in weeks, enabling immediate network turn-up.
• Direct-to-Engineer Engagement: Connects customers directly with 100% US-based optical transport specialists, bypassing lower-tier help desks and scripted queues entirely.
• Expedited Advance Replacement: Replaces standard 10-to-15 business day depot repairs with priority-dispatched, pre-configured replacement units with zero license-activation friction.
• Hitless Maintenance & Firmware Integrity: Delivers supported In-Service Software Upgrades (ISSU) and security patches, updating management firmware while keeping client and line-side traffic fully active. 
• Deep Optical Diagnostics: Provides root-cause optical telemetry—including power budget, OSNR, eSNR, and Q-factor analysis—to resolve physical-layer degradation before service is impacted.

“Operators are frustrated by waiting months for hardware, only to be routed to call-center scripts when critical assistance is required,” said Casey Inman, Director of Sales & Marketing at XKL. “By pairing weeks-long delivery with CoreAssure, we provide true operational predictability—delivering capacity when it is needed and backing it with direct engineering expertise.”

Availability

CoreAssure extended service solutions are available immediately across XKL’s DarkStar® product line, spanning the MediaLight and SpectraPath™ product families. For product information, visit xkl.com/products/.
