About the different sections:
WDM & Optical Transport
  WDM & Optical Transport Solutions consists of scalable Wavelength Division Multiplexing
  (WDM) systems specifically designed for businesses and service providers that require flexible,
  compact, cost-effective systems that will multiplex transports and protect high-speed data,
  storage, voice, and video applications.
   Having more than 15 years of experience in the design and manufacturing of fiber optic systems
   and network infrastructure equipment, MRV has earned a world-class reputation as optical
   transport innovators. MRV was the first to use multimode extension (MMX) technologies and
   CWDM with 16 wavelengths multiplexing. MRV was the first to develop SDI interfaces in the
   SFPs (Small Factor Pluggable) format. The unique optical-layer design of MRV's equipment
   supports in-service migration of CWDM to DWDM throughout the entire chassis range. The
   flexibility of MRV's products, combining CWDM and DWDM, advanced TDM multiplexing,
   and all-inclusive optical cards designed for pluggable optics (SFP/XFP) interfaces, offers service
   providers a lower initial cost, allowing for starting with fewer channels units, while ensuring
   simple system upgrades or future network reconfigurations, and keeping minimal spares
   inventory and maximum end user flexibility.

LX Series

   MRV’s Out-of-Band Networking product family is designed for organizations who are unable to
   afford the economic and business consequences of downtime. By extending service port access,
   power management and sensor networking capabilities over IP networks, MRV provides system
   awareness and control from virtually anywhere. Unlike any other general terminal server or
   console management solution, the LX Series is optimized to provide a secure and converged
   solution, offering serial connectivity, console, power and sensor management capabilities.

Wireless
  Wireless Optics (also known as “Fress Space Optics” or “Optical Wireless”) is an optical data,
  voice and video transmission system. Like fiber optic cable, wireless optics communication
  systems use laser light to transmit a digital signal between two transceivers. However, unlike
  fiber, the laser like is transtmited through the air (free-space) instead of through a glass strand. In
  order for the digital signal to be transmitted and received, there must be clear line of site between
  each wireless optics unit. In other words, there should be no obstructions such as trees or
  buildings between the transceiver units.
  FSO is primarily deployed where performance, security, rapid deployment, and cost-savings are
  critical issues. The TereScope™ line of wireless optics products from MRV, ranging from
  1.5Mbps to 2.5Gbps in bandwidth, provides a solution for any protocol in common use both in
  Carrier and Enterprise networks.
  The family divided to two different sections:
    ActiveTereScope - The Optical Wireless TereScope family. Operating at data rates of 1.5Mbps
    to Gigabit speeds, TereScope™ systems are deployable in one day.
    Passive TereScope - The Terescope 1 (TS1) an all-optics innovative modular solution for
    wireless optical communications without electronics. TS1 is an optical transceiver, which sits
    on rooftops (or behind windows) and provides fiber-like connection and speeds without
    electronics or electricity power.

   Cross-connects are physical layer switches that create connections from any port to any other port
   on the device. These devices are used in a variety of applications. A cross-connect is used
   primarily as an intelligent patch panel. Whereas with a typical patch panel, wires must be
   physically disconnected, moved, and reconnected to change the network configuration, with a
   cross-connect, the network administrator can make any desired configuration changes without
   touching the physical wires. This is accomplished by providing a fully programmable path
   between all the ports on the cross-connect.

NMS
  MRV Communications’ MegaVision Pro® is a full-featured, SNMP-based Network Management
  System (NMS). It provides comprehensive management and control for all MRV
  Communications manageable products including FiberDriver®, OptiSwitch®, TereScope® and
  LambdaDriver®. MegaVision Pro product also includes the EventHorizon Fault Management
  system.
  MegaVision Pro combines complete end-to-end network viewing and performance monitoring
  with robust configuration and fault management features. In addition, MegaVision Pro
  automatically detects and monitors any SNMP or TCP/IP compliant device from any vendor.

Pluggable Optics

   modules support different optical interfaces, including CWDM optical interfaces for the different
   MRV product lines.

Services & Support Programs
   MRV offers a variety of top-quality customer-oriented support & service programs. These
   programs are designed to assist our Partners, Authorized Resellers and Distributors of various
   skill and responsibility levels.
