How To Use A Dual SFP Fiber RTU To Create A Redundant Monitoring Network

How fast is fiber spreading at your company? Is your monitoring keeping up, or are new sites being turned up without enough visibility? As fiber continues to grow, you need RTUs that can leverage the fiber transport that's available at your remote sites.

Get a Reliable RTU That Features an SFP Fiber Interface

The field-proven NetGuardian 832A G5 has a new build option that has dual SFP fiber ports (GigE). These ports allow you to route alarm data over SFP fiber. You can also daisy-chain many NetGuardians together across your network for a highly efficient architecture. This also creates a new monitoring network that is separate from your payload network. This creates valuable redundancy that you can use to remotely access site gear - even when your payload network is down.

This RTU with Dual SFP Fiber Ports (GigE) can be daisy-chained to create a backup monitoring network separate from your payload network.

The ability to remotely access site gear during a main LAN failure can also provide outstanding revenue protection. One of the main benefits includes lessening downtime by making repairs without driving out to the site. This saves your company money, time, and energy. Your NetGuardians will provide backup 10/100/1000BaseT LAN access to a lot of site devices using their on board switches. Your remote units will still be able to report your alarm notifications to your or your central master station (T/MON), but now via SFP fiber. Get a good night's rest knowing that you still have LAN connectivity via SFP fiber from the NetGuardians you've deployed.

In this diagram, you can see that LAN is sent across fiber and delivered via the NetGuardians on-board switch to external devices. Remember, this connectivity is in addition to the core monitoring functionality (32 discretes, 8 analogs, 8 controls, 8 terminal server serial ports...) offered by the NetGuardian 832A G5.

While considering these new fiber-based opportunities, don't forget that this isn't just any RTU. It's a NetGuardian 832A G5. You're investing in a field-proven, full-featured alarm remote unit. Various NetGuardian 832A G5s with different build options have been used in hundreds of networks worldwide.

Benefits of the NetGuardian 832A G5 Include

  • High Capacity: 32 discrete alarms (expandable up to 176 alarm points by daisy-chaining 3 NetGuardian DX Expansion Units), 32 ping alarms, 8 analog alarms, 8 controls, and 8 serial ports.
  • Reports alarms via SNMPv1, SNMPv2c, SNMPv3, or DCPX protocol.
  • Ping method via SNMPv1 GET - Get more important status info from your ping targets.
  • Reports alarms to a lot of SNMP managers or TMon Remote Alarm Monitoring System so it's easier than ever to support a more secure backup master architecture.
  • Dual Ethernet support for secure network access, both NICs have access to the NetGuardian but not to each other.
  • 8 high-speed (110K) serial ports provide a lot of user LAN-based reach through access to PBXs, switches, and any other device with a craft port or serial only interface. (Similar to terminal server functionality).
  • 4 port 10/100 switch provides LAN to site devices. It allows functionality with the NetGuardian SiteMON IP for visual site surveillance.
  • RADIUS authentication option.
  • Alarm point grouping provides alarm levels, custom virtual alarms, and more.
  • RoHS 5 approved for overseas clients that need RoHS compliant units.
  • Dial-up reporting path in case of main communication path failure.
  • Monitor via Web browser.
  • Receive E-mail and pager alerts.
  • Free lifetime firmware upgrades.
  • Free Windows-based utility for off-site editing and remote provisioning via LAN.

4 Key Benefits of Using the NetGuardian 832A G5's Fiber Interface vs. Copper

  • Enhanced Security.
  • All-In-One RTU and 3-Port Media Converter.
  • No Electromagnetic Interference (EMI) Problems.
  • Immunity to Lightning Strikes.

What if I need a custom unit with a Fiber Interface?

If the NetGuardian 832A G5 fails to meet your system's needs, DPS can create a custom unit for you through vertical integration. DPS Engineers work together with the Production staff to build the perfect remote units for their clients. Almost all of DPS Telecom's products are manufactured in-house. This gives DPS full control over the production process and allows us to meet or exceed our clients' needs. If there's a unit that needs to be customized to fit your needs, DPS can definitely create it for you. Read about Frank Fetchak, a Network Engineer at Consolidated Communications, and his experience working with DPS Telecom to create a perfect custom unit to fit his company's monitoring application.

Quality and Reliability: Are DPS products really that good?

DPS Telecom has been around for nearly 3 decades! In that time frame, DPS has either provided a solution or assisted their clients from all over the world with their monitoring needs. DPS Telecom believes in their products and offers you a 30 Day No-Risk Money-Back Guarantee, a long-term client relationship commitment, and 24-hour emergency technological support, as well as other client services that no other company in this industry can match.

Real-World Application

Collect Alarms Over Fiber and Mediate them via LAN to Your SNMP Manager
Collect Alarms Over Fiber and Mediate them via LAN to Your SNMP Manager

Equipment Used:

  • 8-Point Alarm Collection Box
  • Fiber-to-LAN SNMP Agent
  • SNMP Manager

How This Application Works

This solution provides the ability to collect up to 8 alarms inside the SCIF, and transmit those alarms via fiber outside the secure environment where the alarms will then be converted to SNMP V3 over 10BaseT LAN.

The fiber interface is critical to this application in that it eliminates a potential antenna source from the SCIF.

Originally, we had discussed SNMPv3 as an option, but because the incremental cost of SNMPv3 was not that high, coupled with the other benefits of that platform, it just made sense to move forward with the SNMPv3 approach.

DPS has a very talented pool of engineers and who routinely work on new products and packaging to create "perfect fit" solutions for our clients. We think you will be able to see from the application that this design is complete, clean and straight forward. There is no "kluge" of existing technology that forces extra user installation work, time or materials.
