Transport Hardware Report

  • The worldwide optical market grew by 8% as supply chain constraints eased. Most vendors began to draw down the massive booking backlogs accumulated throughout 2022.
  • The worldwide routing market grew 15%, its fifth quarter of growth in the past six quarters.
  • Supply chains are improving, but the tenuous macroeconomic situation is causing some network operators to postpone delivery of ordered hardware by several quarters.

Transport Applications Report

  • 400ZRx port shipment growth stalled hyperscale users absorb inventory, but it is still up over 65% YoY. More than a quarter of all coherent ports shipped this quarter were 400ZRx.
  • ROADM line card shipments grew 10%, slightly higher than overall optical hardware market performance during 1Q23 (8%).
  • Compact Modular sales again outperformed the overall optical market this quarter and were up +15% YoY worldwide. Sales at Cisco declined -74% as hyperscale customers paused new orders while they absorbed inventory.
  • OTN switching hardware sales grew 15%, marking the third straight quarter of growth following eight consecutive quarters of YoY decline. A spending resurgence in India has primarily driven this growth.

Optical Components Report

  • Datacom optical component revenue plummeted -20% YoY as inventory adjustments by large equipment companies and hyperscale operators hit hard.
  • Telecom optical component revenue was down sharply (-13%) for similar reasons.
  • 400GbE module shipments declined across the board in all reach specifications and from all vendors. DR continues to be the most popular format, with more than 60% of 400GbE ports shipped using that format.
  • A nominal number of 800GbE modules shipped and large-scale shipments will not start until the associated Ethernet switches with 100Gbps PAM4 interfaces are commercially available later in 2023.
