Recent findings from Dell’Oro Group indicate that the Optical Transport equipment sector experienced a 14 percent annual growth rate in the second quarter of 2025. This growth is linked to increased interest in disaggregated Wavelength Division Multiplexing (WDM) and data center interconnects.

Market Recovery

According to Jimmy Yu, Vice President at Dell’Oro Group, the market recovery, which follows a period of six quarters with declining sales, demonstrates the strong demand for disaggregated WDM solutions. These solutions provide network operators with flexibility in selecting suppliers, promoting a vendor-agnostic environment.

The 2Q 2025 report features several notable points:

  • Growth in both optical transport systems and ZR/ZR+ optical plugs contributed to the market's annual revenue increase.

  • Communications service providers observed a slight revenue increase compared to last year, while cloud providers accounted for a substantial share of the optical revenue growth, with a 60 percent increase in WDM system purchases.
  • The top revenue contributors for the quarter included Huawei, Ciena, Nokia, ZTE, FiberHome, and Cisco.
