For corporations to maintain profitability in today’s marketplace, they must maintain the reliability, security, and safety of their telecommunications network. In order to achieve the required degree of hardness from lightning in telecommunications networks, the two most critical requirements which must be established and maintained are communication isolation and power supply surge suppression.  They can be most efficiently and economically provided using: (1) fiber communications isolation from a remote ground using Fujitsu’s FLASHWAVE and (2) AC power line surge protection using Northern Technologies’ V3 Shield Technology.

FLASHWAVE fiber solution from Fujitsu Network Communications is a very simple solution for an exposed telecommunications network. A solution that provides an OC-3 SONET platform to the very edge of the network and connect down to DS1 or DS3.

Fujitsu has a total SONET fiber network solution both backbone and end units using its new Flashwave 4010 remote extension platform. This end platform is a compact OC-3 access device that is optimized for simplicity and low cost to enable optical delivery of DS1 or DS3 services. This platform provides a advance feature set to reduce the complexity of installation and turning up of new services. It is barely larger than a cigar box at half the weight, and is under $7K!

In addition, a Fujitsu fiber entrance facility system is being developed that will offer a turnkey fiber system at DS0. This system will support either fiber directly from the Central Office (CO) or copper initially to the 300V-Point from the CO and fiber from the 300V-Point to the substation. Later, the copper interface at the 300V-Point may be removed and fiber brought all the way into the substation, when the telephone company is able to offer fiber connectivity directly from the CO. This ‘fiber entrance facility’ system, providing a copper to fiber interface, will be ready in the fourth quarter.

AC Power line surge protection using Northern Technologies’ DMK Series TVSS / V3 SHIELD will fully protect telecommunications equipment from lightning power surges. This equipment provides non-degrading, bipolar SAD technology with the lowest possible clamping voltage and fastest responsible time available in the industry today.

This equipment’s technology provides thermal protection against prolonged over voltage conditions, and allows actual peak pulse current to be handled by the suppression module, well in excess of traditional fused modules. Independent primary SAD suppression and secondary MOV suppression insures continued protection, and this equipment is provided with remote failure indication for long distance monitoring.
