Metro Networks & WDM Capacity Expansion

When conduit is full and leasing fibre is expensive, wavelength multiplexing is usually the cheapest capacity upgrade available — it multiplies a single fibre pair instead of adding one.

Built for the Networks You Operate

  • CWDM: 18 channels, 1270–1610 nm, lowest cost, unamplified links
  • DWDM: C-band, 40+ channels, for longer spans and higher capacity
  • Plan a channel grid with the head end before ordering optics
  • Confirm amplifier type: EDFA requires DWDM, not CWDM channel spacing
