These are the main Optimum Gig plans. They provide fiber options:
1 Gig Fiber ($60)
2 Gig Fiber ($120)
5 Gig Fiber ($180)
With fiber you can get upload speeds equivalent to your download speeds.
As well as being fast, Gig plans are known for low latency. They are constructed of glass, or fiber optic materials. Unlike cable connections, the speed doesnt suffer due to distance from the source. Also, these connections are more resilient in times of bad weather or emergencies.
