While early optical connector and cabling solutions themselves provide advantages over copper,more recent optical solutions extend this advantage considerably.In the mid-1980s，optical fiber was introduced into data prossing communications.At regularintervals,suppliers debeloped higher density connectors in lockstep with optical transceiver manufacturesand original equipment manufacturers (OEMs).Multifer connectors have been developing for some time.Early ESCON connectors were quite bulky for handling two fibers.Denser solutions such as the MPO connector allowed the same two fibers to be contained in less linear space.Liner board space.Linear board space,though,is not the appropriate measurement of density.To make the most efficient use of the available space ，designers can resort to multirow fiber arrays in which one has to think in two dimensions (width and height).As a result,the same MPO connector has been expanded to contain 72 fibers in the same liner space as was occupied by only two fibers.Recent Electrotechnical Industry Association/Telecommunications Industry Association(EIN/TIA) standards proposals call for arrays of up to 96 optical fibers contained in this same size connector,and technical proposals postulate over 250 fibers in the same linear space.
The resulting improtant metric is the toal mating density(TMD)for a given total mating area (TMA)。A two-dimensional(2-D) connector can greatly increase TMD.A two-fiber MPO connector would,for example ,have a TMA of 3.0x 5.0mm=15mm^2 and thus a TMD of 2 fibers/15mm^2 and thus a TMD of 2fibers/15mm^2=13 fibers/mm^2.Conbersely,a 72-fiber MPO style connector has 6 rows of12 fibers for a TMD of~4.8 fibers/mm^2.While the transition from an ESCON connector an MPO connector increased fiber density by only a factor of about 2.5,the transition from two fiber MPO connector to 2-D MPO conectors has increased fiber of 90 times over the past 20 years, driven largely bu the move to 2-Darrys.
MTP MPO Fiber Cable is offered for various applications for all networking and device needs like 100 Gig modules. It uses a high-density multi-fiber connector system built around precision molded MT ferrule. Fiberstore’s MPO fiber cables are available in UPC and APC finishes, support both multimode and single mode applications, and optional lengths available. Our MPO/MTP fiber cable is with push connector IEC 61754-7 and TIA/EIA 604-5A compliant and offer low cost per termination for high density applications. The MPO/MTP fiber cables are tested with guaranteed quality, and they can be installed easily, which saves time and money.
By themselves thees dense connector solutions can greatly simplify structured cabling solutions by aggrgating fibers in systems employing traditional serial or small parallel fiber optic transceibers in systems employing traditional serial or small parallel fiber-optic tranceivers. The increased cabling density can directly reduce the space demands of systems.With properly designed optical can provide very reliable and consistent assembly process,high-density optical assemblies can provide very reliable and repeatable performancd,meeting the needs of the server and storage community.Compared with copper interconnections,these is a dramatic size and weight savings and a cost benefit,Considering these factors alone,one can build a strong case in favro denser optical conneections.Howerver,interfacing these dense connectors directly with corresponding dense energy -efficient active optical can result in the major benefit of increasing board channel density while simultaneously lowering the cooling requiremnts.
Cost-effective multimode polymer waveguides, suitable for use in high-speed on-board optical interconnections, are presented. The fundamental light transmission properties of the fabricated waveguides are studied under different launch conditions and in the presence of input misalignments. Low loss (~0.04 dB/cm at 850 nm) and low crosstalk (<-30 dB) performance, relaxed alignment tolerances (plusmn20 mum) and high-speed operation at a 10-Gb/s data rate are achieved. No degradation in the high-speed link performance is observed when offset input launches are employed. Moreover, a range of useful waveguide components that add functionality and enable complex on-board topologies are presented. The optical transmission characteristics of the fabricated components are investigated and it is shown that excellent performance is achieved. Excess losses as low as 0.01 dB per waveguide crossing, the lowest reported value for such components, and bending losses below 1 dB for 90-degree and S-shaped bends are obtained even with multimode fiber . Moreover, high-uniformity power splitting and low-loss signal combining are achieved with Y-shaped splitter/combiners while a variable splitting ratio between 30%-75% is demonstrated with the use of multimode couplers. Overall, the devices presented are attractive potential candidates for use in on-board optical links.
Optical interconnect is a way of communication by optical cables. Compared to traditional cables, optical fibers are capable of a much higher bandwidth, from 10 Gbit/s up to 100 Gbit/s.The technology is currently being introduced as a way to link computers to mobile devices, as well as on motherboards and devices within computers.
