Comba Telecom Launches Optical Expansion Unit for its CriticalPoint™ Public Safety DAS Solution 

Optical Expansion Unit adds ability to add millions of square feet of coverage for Public Safety DAS Systems


(11 August 2019 – Milpitas, CA) – Comba Telecom, Inc. today announced the expansion of its 700/800MHz CriticalPoint™ Public Safety DAS product line to include a Fiber Optical Expansion Unit to extend Land-Mobile-Radio (LMR) public safety in-building communications signal coverage.

The new CriticalPoint Fiber Optical Expansion Unit offers two options, a 4-port or 8-port model.  Each unit can expand Comba’s DAS solution, based on the number of ports, to add either 4 or 8 additional Remotes to the system for greater system coverage.  Additionally, up to 3 Fiber Optical Expansion Units can be daisy-chained together to allow a maximum of up to 32 Remote Units to be controlled and managed by a single Comba DAS Master Unit.  These expansion units support any of Comba’s DAS Class A or Class B models and do not interfere or limit any of the systems overall features such as Automatic Gain Control (AGC) or Channelized Squelch. 

“We are excited to add an expansion unit to our public safety Fiber DAS product line,” says Don Henry, Comba Telecom’s VP of Sales and Public Safety Program Manager. “We complete our public safety DAS product line up by now offering a solution that covers extremely large buildings or multiple buildings such as in a school or work campus environment.  It also provides the building owner a cost-effective solution without having to duplicate multiple systems.” Henry continued to state.
