MRV Launches Optical Media Converter For Carrier Ethernet Service Demarcation Applications

CHATSWORTH, Calif.--(BUSINESS WIRE)--MRV COMMUNICATIONS, INC. (Nasdaq: MRVC), a leading provider of products and services for out-of-band networking, WDM and optical transport, Metro Ethernet, fiber optic components, 10GE and other service aware networking products, today announced a new Fiber Driver® EM316EUSM media converter module that delivers managed, optical Ethernet demarcation for bookend pair applications between the central office and a customer's network.

The Ethernet Universal Service Module (EUSM™) is MRV's newest addition to its industry-leading suite of intelligent media converter-based optical Ethernet solutions and maximizes network uptime by providing advanced services including full-service level control over link connectivity and WAN/LAN segment provisioning. The bookend EUSM solution uses extended OAM 802.3ah protocols to fully manage both ends of the point-to-point fiber optic link from a single manager at either end. Central office and customer premises link ports on the respective modules are controlled similarly from the managed side of the link.

Additionally, the MEF 9 and MEF 14-certified module features the industry's most advanced service assurance features that maximize uptime and reduce capital and operating expenses. The EM316EUSM offers either a fiber or copper port for 10/100/1000 Ethernet input, and dual, redundant, SFP-based output ports to a fiber WAN. The module performs as an end-point or intermediate-point service demarcation in transparent LAN services (TLS) or in Ethernet signal repeating applications, as part of an end-to-end managed Metro Ethernet network. The EM316EUSM includes Metro Ethernet capabilities generally available only in higher-end Metro Ethernet devices, such as VLAN-awareness, per flow policing, Q-in-Q VLAN stacking, VLAN translation and built-in hierarchical multi-layer optical link redundancy.

"This module delivers the next generation in MRV's overall strategy to add more intelligence and remote management to media converters, to ease the management challenge and reduce OpEx in dense carrier, MSO and enterprise applications," said Noam Lotan, president and CEO of MRV Communications.

"The EUSM makes the Fiber Driver chassis - which is already one of the most versatile optical multi-service platforms on the market – suitable for a new range of applications."

The EM316EUSM integrates multi-layer performance monitoring (RMON and HCRMON), as well as advanced tools for SLA assurance, including hardware-based traffic generation (up to full Gigabit Ethernet speed), non-intrusive per VLAN loopback and sophisticated real traffic analysis (packet loss, delay and jitter measurement) well exceeding the requirements of IEEE and ITU standards. Other built-in features include SFP-based digital diagnostics (SFF-8472), extensive optical performance monitoring and copper TDR physical line defect detection capabilities.

The module is immediately available from MRV sales representatives worldwide. More information is available at www.mrv.com/fiberdriver.
