PD-LD is offering direct alternatives for discontinued Zarlink Semiconductor devices. PD-LD offers drop-in replacement components to alleviate the need to change existing printed circuit boards.
Zarlink products that have been discontinued include 1300nm LED transmitters and Photodiode receivers, both of which are designed for operation with multimode optical fibre and used in a wide variety of applications for analogue and digital transmission.
Four varying receptacle styles are available that are compatible with industry standard fibre optic connectors. These components are used by a wide cross section of industries, including communication equipment manufacturers, test instrument producers, video transmission equipment builders, and sensor makers. The components will allow equipment manufacturers to continue to offer their products without having to redesign legacy product lines.
