GPS Fiber Transport – Timing Solutions

Cellular wireless networks, public safety wireless networks and data networks, all require highly precise timing signals to synchronize data transfers and handoffs. The faster the network, the more precise the timing signals must be.

The most accurate and ubiquitously available timing reference is from the Global Navigation Satellite System (GNSS), aka GPS (Global Positioning System). Many networks utilize timing servers at their central hubs. These servers need a connection to a GPS antenna to generate the timing signals and distribute to connected devices. In very high-speed networks, this approach is limited to nearby devices.

The simplest, most reliable and most accurate approach is to provide direct GPS RF connections to all devices that are configured to accept it. Optical Zonu’s GPS Fiber Transport is optimized to provide connectivity for both single connection and distribution to over one hundred connections.


• Compact, Antenna Unit – can be mounted indoors or outdoors
• Rack mounted fiber optic Base Unit recovers the GPS RF signal with up to 16 GPS connections
• The fiber from the Antenna Unit can be optically split up to 8 ways providing up to 8 x 16 = 128 connections from a single Antenna unit
• Available with auto-redundancy switchover to a 2nd GPS antenna path for added reliability (within the same compact size)
• Patented optical alarm reporting – eliminates need for a separate computer monitoring set up
• Low profile design with lightweight fiber distribution, the only solution permitted in many switching centers
• NEBS Level 3 permits installation in Central Offices
• Only solution approved by all 4 US mobile wireless carriers
• Can be simplified for simple situations.


• Made in the USA
• Simple installation and integration into a system Network Management System (NMS), minimizes time and cost of integration
• Compact Antenna Unit and low-profile Base Unit minimizes space needed
• Auto-redundancy ensures highest reliability in crucial installations
• RF-over-Fiber design ensures lowest cost, highest reliability

Who do we compete with?

• Intellibs – approved by Verizon only. Large units, complex set up a computer monitoring required. More expensive.
• Vialite – UK based. Not approved by US carriers.
• GPS Source – active coaxial solution. Cost-effective for small sites when GPS antenna is close to the base station gear. Awkward for larger sites where long runs of ½ inch coaxial cable is needed. Not permitted in many switching centers and central offices
• PTP Timing – PTP timing servers themselves require a GPS connection but the timing signal itself can be routed to many devices. Subject to errors over long distances.

Unique fiber optic transport solutions for Wireless/Cellular communications: Cellular BaseStation(s) to/from DAS – universal transport

What is ZONUConnectTM?

One of standard solutions to providing uniform mobile wireless coverage in buildings is to deploy a Distributed Antenna System (DAS). For smaller sites, this can be a passive system using coaxial cables and splitters connecting to antennas distributed throughout the building. For larger sites, an active DAS is deployed. These systems convert the mobile wireless RF signals to optical and distributes these signals over optical fiber to antenna units that convert the optical signal back to RF.

It is often the case that, because of space limitations or access, the carriers that want to connect to a DAS may have to locate their base station radios off-site. There are several ways to connect to a remote DAS but, in most cases, ZONUConnectTM provides the most efficient solution in terms of cost, rack space and fiber count. It also gives the carrier full access to his equipment and minimizes maintenance problems.


• Selection of interfaces to connect to any base station configuration and any combination of services
• Scalable for any number of sectors
• Broadband RF-over-Fiber using CWDM
• Distances from 300ft to 12 miles
• Computer-controlled local and remote set up, commissioning along with SNMP remote monitoring
• Connects to any DAS


• Made in the USA
• Minimum rack space – DAS sites are having increasing shortage of rack space. Carrier’s must also pay for space used
• Common connectivity from central location to multiple DAS sites simplifies maintenance and lowers cost
• Minimum fiber count – availability of dark fiber is often a problem. Cost of leasing dark fiber is minimized
• Guarantees full access – CPRI to Remote Radio approach leaves part of the carriers’ base station equipment on the property of the 3rd party DAS owner with no or limited access
• Ensures maintenance demarcation point for 3rd party DAS, all DAS-specific remote connectivity solutions require that part of the DAS be located off-site at the carriers’ property. ZONUConnectTM ensures that 3rd party DAS equipment is only on the property of the 3rd party

Who do we compete with?

• Teko (JMA) – Teko has a DWDM solution that uses more rack space and is considerably more expensive
• Corning – the CorningOne solution is optimized for use with the CorningOne DAS. It is more expensive that ZONUConnectTM, uses more fiber, and requires that part of the DAS headend be installed off-site on the customer’s property
• CPRI (Common Public Radio Interface) to Remote Radio Head - digital single channel transport. The base station usually consists of two components – the Base Band Unit (BBU) and the Remote Radio Head (RRH). The BBU handles the digital processing and backhaul link to the network hub. The RRH is the RF front end and connects to the BBU via a fiber optic CPRI link. Deploying the RRHs at the DAS headend leaves part of the base station at a 3rd party property with no access. It also using more space, more fiber and more power than ZONUConnectTM which the customer pays significantly higher price.

WE ALSO OFFER AN ANTENNA EXTENDER family that provides simple solutions and stand-alone DAS for small deployments.
