CWDM/DWDM Mux/Demux and OADM are common fit in with Passive. CWDM and DWDM technology present an efficient approach to share one set of fiber strands as well as set together various communications interfaces like: 10G, SONET OC-192, STM-64, Fiber Channel 1G/2G/4G, Gigabit Ethernet, OC3/OC12 or OC48 and E1/T1, just by using different wavelengths associated with per channel. Thus they can expand the capacity with the network without laying more fiber. I would like to introduce the particular basical description of CWDM Mux/Demux, DWDM Mux/Demux and OADM.
You know, Mux (Multiplexer) products combine several data signals into one for transporting over the single fiber. Demux (Demulitplexer) separates the signals in the other end. Each signal is a some other wavelength.
The Coarse Wavelength Division Multiplexing-CWDM Mux/Demux is often a flexible plug-and-play network solution, which helps insurers and enterprise companies to affordably implement denote point or ring based WDM optical networks. CWDM Mux/demux is perfectly created for transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks. CWDM products are popular in less precision optics and lower cost, un-cooled lasers with lower maintenance requirements. Weighed against DWDM and Conventional WDM, CWDM is much more economical and less power consumption of laser devices. CWDM Multiplexer Modules can be found in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 too much electronic products, send on them someone optical fiber and after that de-multiplex the signals into separate, distinct signals for input into gadgets across the opposite end for your fiber optic link.
The Dense Wavelength Division Multiplexing-DWDM Mux/Demux Modules are made to multiplex multiple DWDM channels into one or two fibers. Based on type CWDM Mux/Demux unit, with optional expansion, can transmit and receive as much as 4, 8, 16 or 32 connections of various standards, data rates or protocols over one single fiber optic link without disturbing one another. DWDM MUX/DEMUX modules offers the most robust and low-cost bandwidth upgrade on your current fiber optic communication networks.
OADM(Optical Add-Drop Multiplexer) is often a device found in WDM systems for multiplexing and routing different channels of fiber into or out of a single mode fiber (SMF). OADM was created to optically add/drop one or multiple CWDM/DWDM channels into a few fibers, provides the power to add or drop a single wavelength or multi-wavelengths from a fully multiplexed optical signal. This permits intermediate locations between remote sites gain access to the regular, point-to-point fiber segment linking them. Wavelengths not dropped pass-through the OADM and carry on towards the remote site. Additional selected wavelengths may be added or dropped by successive OADMS if required.
Luma Optics supplies a wide array of passive optics. The modules are customizable with a collection of WDM/CWDM/DWDM modules and CWDM OADM or DWDM OADM. Luma Optics may be the correct solutions to request guidance to be used of CWDM, DWDM or WDM technology. CWDM and DWDM Mux/Demux present an ideal balance of price and gratifaction for multiplexing and demultiplexing in Metro/Access networks.
SFP+ (Small Form-Factor Pluggable) are the upgraded version of the former SFP transceivers (mini GBIC), with higher data rate and new industrial standards. It is smaller than any of the currently shipping form factors and provides the highest density per line card. SFP+ offers customers both immediate benefits and long-term advantages in supporting evolving data center needs. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. It is a international industry format supported by many network component vendors.
SFP+ is an innovative, next-generation transceiver module. Initially, it is targeted to support speeds of 10 Gbps for next-generation Gigabit Ethernet applications and 8.5Gbps Fiber Channel systems. What is more, SFP plus is with lower power consumption for less than 1W and it is even cost effective. These transceivers are with managed digital optical monitoring and superior high temperature performance.
Several industrial acknowledged standards for SFP plus has been released for 10Gpbs networks, including 10Gbase-SR, which define the SFP plus transceiver working with OM3 10G multimode fiber at 30 to 300 meters range, 10Gbase-LR which define the SFP plus transceiver working with single mode fiber at 10km range, 10Gbase-LRM which define the FDDI multimode fiber at around 220 meters range.
Compare With XENPAK or XFP Modules
In comparison to earlier XENPAK or XFP modules, SFP+ module is with more compact size compared with the former 10G transceivers X2 and Xenpak, leave more circuitry to be implemented on the host board instead of inside the module.
The advantages of SFP+ modules:
SFP+ Has A More Compact Form Factor Package Than X2 And XFP.
It Can Connect With The Same Data Rate Of XFP, X2 And XENPAK Directly.
The Cost Of SFP+ Is Lower Than XFP, X2 And XENPAK.
SFP+ Transceiver is interchangeable with SFP transceiver and can be used in the same cages as SFP transceiver. For 10G applications, SFP+ transceiver has a smaller footprint and lower power consumption than XFP transceiver. The electrical interface to the host board for SFP transceiver and SFP+ transceiver is the same serial.
Many companies, such as Cisco, Finisar, and Sumitomo, have released SFP+ transceivers. SFP+ ensure the 10Gbps data transmission and the most densely installation capability as well as the lowest cost, currently it is well acknowledged as the ultimate choice for the 10Gbps fiber optic transceivers. Among them, Cisco SFP+ transceiver is the mainstream market. Cisco 10Gbase SFP+ transceivers are used for high speed 10Gigabit Ethernet, linking the equipment to fiber optic networks. Cisco SFP+ products include active SFP+ cables and SFP+ transceivers. There is also copper transceiver available from Cisco.
It is with great pleasure that we announce the official launch of our new LumaOptics website. A shout-out to the website design team, graphic designers, and everyone at LumaOptics for all your support. We've been supplying optical transceivers for many years now and we've seen and heard it all. We never stop listening and taking notes and asking questions and more questions. The optical market needs a new paradigm and we're at the center of that tidal shift in delivering it to you. Stay tuned...in 2013 LumaOptics will be making a big splash at an event near you.
