What Our Customers Said

Arif Afriandu

I'm really happy with the combination of HTF's powerful WSS and 400G DWDM solution. The flexibility in optical signal routing is great. It gives us high-capacity bandwidth that meets the 400G era's needs. The upgraded DWDM network is very useful. It helps us serve customers with high-speed and cost-efficient connectivity. This has made our network performance and customer service experience much better.

Kit Smith

HTF 400G DWDM solution has far exceeded our initial expectations. With a transmission capacity of 400G per channel and 64 channels in total, it reaches an astounding 25,600G. These numbers aren't just impressive on their own; they perfectly align with and satisfy our ever-increasing capacity demands, providing us with the scalability we desperately needed to stay ahead in our operations. Thanks for the HTF team's support.

Mark Lanctot

The HTF team gave excellent support in the large expansion project with a tight timescale. Their expertise and commitment were key to network upgrade via DWDM. Working efficiently, they made the process smooth and on time, meeting our urgent need and exceeding expectations. We're very grateful.

Erik Holbrook

HTF’s alien wavelength DWDM technology allows us to upgrade our existing network by ten times the capacity of our legacy infrastructure. The 100G/200G/400G single lambda is a breeze to use, slashing costs. And it meshes perfectly with existing gear. We're beyond grateful and highly recommend it.

Patrick Blesso

We were desperate to upgrade to 200G capacity on a single fiber but hit a huge snag – a 42dB fiber loss over 120KM! That's when HTF stepped in. Their team's talent shone through, quickly grasping our issue. With their support and a tailored DWDM solution, we overcame the hurdle. Heartfelt thanks to HTF!
