Opnext Introduces LX4 Module in XENPAK and X2 Form Factors; LX4 Module to Support Legacy Fiber Applications.EATONTOWN, N.J. -- Opnext, Inc., a global leader in high-performance optical components, today announced the availability of an LX4 module in the X2 form factor. The LX4 module is a highly integrated, small form factor device capable of transmissions exceeding 300m of legacy MMF See multimode fiber. , as defined in the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.3ae 10GBASE-LX4 standard. These sub-assemblies contain direct modulated uncooled DFB DFB acronym for dark, firm, dry meat. Called also dark cutting beef. lasers resulting in a very economical, low-power budget device. The Opnext LX4 transceivers support layer 2 and layer 3 switches used in premise legacy multimode fiber An optical fiber with a larger core than singlemode fiber. It is the most commonly used fiber for short distances such as LANs. Light can enter the core at different angles, making it easier to connect the light source to broader light sources such as LEDs. (MMF) applications. Legacy multimode fiber is defined as 62.5 MMF with a modal bandwidth The capacity of an optical fiber measured in MHz-km (megahertz over one kilometer). One MHz-km equals approximately .7 to .8 Mbps. Thus, a 100 MHz-km fiber can carry about 70 to 80 Mbps of data. of 500MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. km in the 1.3 wavelength region. Legacy MMF is prevalent in building vertical risers, and in building-building campus link applications. The X2 LX4 module transmits data over four wavelengths, 1275 nm, 1300 nm, 1325 nm, and 1350 nm, by optically combining the outputs onto a single mode fiber making it fully compliant to IEEE 802.3ae specifications. The single mode multiplexer and multi mode demultiplexer operate at the typical LX4 center wavelengths with a spacing of 24.5 nm. "There is strong customer support for the LX4 technology; it is the only proven and robust solution that supports a large percentage of the worst case multimode fiber in the field," said Ed Cornejo, director of product marketing for Opnext. "LX4 is a qualified, standardized solution (Chem.) a solution which is used as a reagent, and is of a known and standard strength; specifically, a normal solution, containing in each cubic centimeter as many milligrams of the element in question as the number representing its atomic weight; thus, a normal solution of silver and we are pleased to be able to offer the module in the X2 form factor." The 10GbE industry has been anticipating greater supplier participation and additional form factor support for the LX4 solution. The Opnext LX4 modules are designed to meet the 10GbE market's cost and volume expectations for both near- and long-term projections. Opnext's technology enables thermal margin for X2 form factor based systems. Opnext will also offer this solution packaged in the XENPAK form factor. Opnext is a founding member of the industry LX4 Trade Goup, formed to promote interoperability and market awareness for the LX4 standard.
