Optics for every network generation
Keep your network moving without replacing what still works.
Network upgrades rarely happen all at once. Source compatible optics for legacy equipment, current infrastructure and higher-capacity deployments — so you can replace failed modules, extend existing assets and upgrade on your own timetable.

Support established platforms
Maintain working links and replace failed transceivers without being forced into a wider hardware refresh before it is needed.
02Operate · Core network capacity
Upgrade in practical stages
Add capacity where demand is growing while established and newer generations of network equipment continue operating side by side.
