O3-xD1 (OC3 to DS1)

"Lightning damage to PCS wireless tower sites [costs] . more than a quarter billion dollars annually"

"The cost for downtime is approximately $75 million."

"Lightning strike damage to PCS cell sites .. results in losses in the hundreds of millions of dollars annually in North America."

Combine the costs of lightning damage with exploding wireless bandwidth demands and it seems obvious wireless links need to be upgraded from copper to fiber.

It may be obvious but it's not cheap. With 100,000 domestic towers, the cost to make a change using conventional methods is measured in billions of dollars.

Fortunately, recent gains in fiber installation efficiency have helped minimize this part of the over-all investment. But costs for the equipment necessary to terminate the fiber and provide standard DS1, DS3 or Ethernet hand-offs to wireless carriers have changed little. Until now.

Pulsecom's O3-4D1 and O3-12D1 family of fiber to DS1 cards change, as the saying goes, everything.

  • First, Pulsecom's cards are standard mechanics, so they plug into copper-based T1 mountings that are often already in place. No cost for mountings.
  • Second, these 400-mechanics cards come in 4-port and 12-port versions. Growth from 4 to 12 circuits requires no extra mounting or space and is a heck of a lot less expensive than putting in 3 conventional 4-port units.
  • Third, Pulsecom's cards are designed to work with existing equipment. That means you can make fiber-to-fiber connections with existing SONET multiplexers rather then buy more of our equipment for the "far end" of a circuit. Is that a 50% savings?
  • Fourth, Pulsecom units have full "GR-1089 outside plant lightning protection" on the DS1 ports to provide extra armor at cell sites. Other equipment that says "DS1 ports are to be connected to intra-building wiring only" lacks this crucial safeguard. That is, why protect against lightning with equipment that lacks lightning protection?
  • Fifth, Pulsecom's units support CWDM wavelengths. They can serve 4-times as many users over the same fiber. That's a lot less expensive than adding more fiber.
  • Sixth, you can start with a Pulsecom OC3 to quad DS1 card, migrate to a DS3 by replacing the card with an OC3 to DS3 unit and then upgrade a network to GigE by replacing the DS3 card with a G2 Gigabit Ethernet unit to ramp your speed to GigE. That's Future Proof scalability from DS1 to DS3 to GigE in the same standard-mechanics shelf.
