White Rock Networks, a provider of optical transport systems for metro markets, announced yesterday it has acquired Seranoa Networks Inc., a Boxborough, Mass., manufacturer of intelligent service edge concentrators. Lonnie Martin, founder/CEO of White Rock Networks, said, "White Rock's current access, transport and switching product family has been successful with carriers because it saves carriers capex and opex dollars in the delivery of both legacy TDM and Ethernet services from the metro core to the fiber's edge. The acquisition of Seranoa's products and technology substantially broadens our market coverage, since their products reduce the costs of terminating and transporting all of the data that comes into a carrier's network from beyond the fiber's edge." In addition, he said, "Seranoa's products open a new market for White Rock with Internet service providers, because they lease expensive transmission bandwidth (rather than operating their own fiber networks), and we can now help them reduce their costs of doing so." Seranoa's current products will become White Rock's VLX300 and VLX400 service edge concentrators and will be supported by White Rock's existing customer service organization based in Richardson, Texas. White Rock is displaying the VLX300 and VLX400 and other products at booth 3014.
