MAKUHARI MESSE, Japan -- Bookham Technology plc (LSE: BHM; NASDAQ: BKHM) today introduced new single-fibre transceiver products for Japanese media converter applications. Enhanced sensitivity enables the products to support larger link budgets of 20dB over a 20km link.The products have been designed to offer additional performance in bi-directional systems carrying 10Mb/s and 100Mb/s encoded Ethernet over a single fibre. They are also suitable for bi-directional SDH STM-1 and SONET OC-3 applications carrying 155Mb/s data. The new products offer two alternatives for customers. The single-fibre transceiver components include a low threshold current Fabry-Perot laser with monitor photodiode. The receiver photodiode is connected internally to a low-noise transimpedance amplifier that features automatic gain control and differential outputs. For customers wanting to reduce their board development time, single-fibre 1x9 transceiver modules are available. These include a dual-loop control laser driver and low-pass filter with limiting amplifier.“For customers already using ASOC transceiver products, the new enhanced sensitivity transceiver offers customers the ability to upgrade link budgets based on the same pin-out and footprint”, said Chris White, Senior Product Line Manager for Active products at Bookham Technology. “For customers with new applications, the 1x9 product offers two-way 20dB link budget on a single fibre from an industry standard module."Bookham Technology PLC
