10Gbps 1550nm APD ROSA
ModuleTek offers a portfolio of ROSAs for use in high performance optical data transmission applications. 10Gbps 1550nm APD ROSA is a fully integrated device with design features that ensure excellent RF stability, together with high sensitivity. The 10Gbps 1550nm APD ROSA offers excellent sensitivity performance for both stressed and unstressed data, coupled with low power consumption.
2.5Gbps 1550nm APD ROSA
This receiver optical subassembly (ROSA) is designed for fiber optic transmission system up to 2.5 Gb/s including PON, SDH/SONET, Gigabit Ethernet and Fiber Channel etc. It consists of a high-performance InGaAs/InP APD and a low-noise transimpedance preamplifier. The chips are hermetically sealed in a 5-pin TO-46 package.
10Gbps 1310nm PIN ROSA
The 10Gbps 1310nm PIN ROSA uses a high-performance InGaAs PIN photo-detector packaged with a transimpedance amplifier designed to meet performance requirements for data rates up to 11.3Gbps data communication over single mode and multi-mode optical fiber at 1310nm. The optical assembly is designed to interface to single mode optical fiber.
1Gbps 1310nm PIN ROSA
The 1Gbps 1310nm PIN ROSA use a high-performance InGaAs PIN photo-detector packaged with a transimpedance amplifier designed to meet performance requirements for data rates up to 1.25Gbps data communication over single-mode optical fiber at 1200nm to 1600nm. Applications include Ethernet, Fiber Channel and ATM protocols.
