TW1 is a 1,300 km submarine telecommunications cable linking the United Arab Emirates, Oman, and Pakistan. It is owned and operated by Pakistani Tier-1 provider, Transworld Associates.
The cable uses DWDM technology with two fiber pairs and has a design capacity of 1.28 Tbit/s. In 2016, Transworld contracted Huawei Marine (HMN) to add 3x additional 100 Gbit/s wavelengths to the TW1 cable system.
