Optimum's latest fiber internet deal, priced at $25 per month, is available for new customers who sign up for 300 Mbps Optimum Fiber internet. The deal locks in the affordable rate for five years and allows new customers to save up to $15 per month by bundling Optimum internet with Optimum Mobile and Optimum TV. The company's price will only increase no more than $15/mo per year until standard rates are reached. The offer includes 5 full years of Optimum's fiber internet, which the brand describes as "blazing-fast." However, there is room for a price increase, which is still a long way away. The price of the service is subject to change each month until canceled.
