Luminent Intros CWDM, SFP Transceivers

COPENHAGEN -- Luminent, a leading supplier of long wavelength transceivers, today announced the availability of a complete Coarse Wavelength Division Multiplexing (CWDM) solution set for metro and enterprise networks. This set includes a newly introduced pluggable Optical Add Drop Multiplexer (OADM), Small Form factor Pluggable (SFP), Gigabit Interface converter (GBIC), and Small Form Factor (SFF) CWDM transceivers in all 16 CWDM wavelengths, and a full line of optical filters for multiplexing/demultiplexing (MUX/DMUX) needs. The use of CWDM in both enterprise and metro networks is a cost effective way to utilize fiber, both to maximize network capacity and upgrade existing network topologies. CWDM is a technique to transmit a large number of channels on a fiber by widely spacing channels across a large wavelength range, unlike Dense WDM (DWDM), which closely spaces channels across a narrow wavelength range. The wide channel spacing facilitates the use of less expensive lasers and WDM passive components since the center wavelength of the equipment does not need to be as precisely controlled. Traditionally, CWDM networks have required a separate optical filtering layer, usually housed in a 1U line card, to multiplex and demultiplex the CWDM signals. Associated therewith is a significant amount of fiber routing and operational complexity. Luminent's patent-pending pluggable OADM is an innovative solution to this problem, and makes CWDM overlays accessible to all its existing customer base. Luminent's pluggable OADM is a modular CWDM Add/Drop filter housed in a form factor slightly larger than that of an SC connector. Additional wavelengths can be added to an existing system on an as-needed basis simply by the addition of a pluggable transceiver and a pluggable OADM filter. This simple architecture facilitates a truly scalable, bandwidth on demand upgrade to existing networks. In a separate release: Luminent, a leading supplier of long wavelength transceivers, today announced the introduction of a complete family of digital diagnostic Small Form Factor Pluggable (SFP) transceivers. These Multi-Source Agreement (MSA) compliant transceivers allow customers maximal flexibility in choosing appropriate physical layer optics for varying applications. The digital diagnostic functionality allows for real time calibrated measurement of key parameters such as optical receive and transmit power, as well as supply voltage, bias current, and module temperature. Luminent's SFP product line is fully compliant with Bellcore GR-468-CORE standards. Data will be available to customers concerning mechanical vibration, mechanical shock, temperature cycling, and accelerated aging. Long reach SFP transceivers are calibrated and tested at five temperatures; data at three temperatures will be shipped with every unit. Luminent's SFP digital diagnostic transceiver family includes 22 different types of transceivers for applications such as Gigabit Ethernet (GbE), Fiber Channel (FC), and SONET/SDH services (OC-3 through OC-48). Dual rate and Multi-rate transceivers are available for OC3-OC12 and OC-3/12/48 applications, ultimately alleviating the operational overhead associated with inventory, sparing, and upgrade.
