Hamamatsu introduces high performance TOSA for Gigabit Ethernet and Fibre Channel applications

May 18, 2004 Bridgewater, NJ--Hamamatsu Corporation is launching the L9278-14 transmitter optical sub-assembly (TOSA) that features a 1310-nm Fabry-Perot laser diode and a conventional 1.25-mm diameter TOSA-type sleeve. Combining the inherent advantages of the TOSA design with Hamamatsu's high reliability and proven performance, the L9278-14 can be used in a wide array of optical fiber communication applications, including Gigabit Ethernet and Fibre Channel.

With a high-speed response of 2.5 Gbits/sec and 0.2 mW optical output, the L9278-14 has the performance necessary for 1310-nm applications. It has a typical spectral half width of 1.0 nm. The Fabrey-Perot laser diode also has typical rise/fall times of 200 psec and a maximum dark current of 100 nA.

Engineers realize a number of benefits due to the L9278-14's small size. It reduces the amount of required board space, thereby providing additional design flexibility. There is also a financial savings associated with the TOSA's compact design. Despite its small size, the L9278-14 consists of a high speed Fabrey-Perot laser diode, optical isolator, and a rear facet monitor diode, which allows for external optical power control.

The L9278-14 is part of Hamamatsu's family of TOSAs, which are optically matched with Hamamatsu's receiver optical sub-assemblies (ROSAs) for transmission of optical signals. Hamamatsu provides a full range of photonic devices and modules that provide high reliability and performance in optical communications applications.

Large quantity pricing of the L9278-14 is $132.00. Samples are available in 4 to 6 weeks.
