CHATSWORTH, Calif.--(Business Wire)--

Level 3, the leading product safety and reliability standard for
telecommunications equipment. MRV is a leading networking company with a full
line of packet-optical transport (POTS), carrier Ethernet, 40G networking and

costs with the confidence that their solution meets the highest level of
standards support," said Noam Lotan, CEO of MRV Communications.
