The 10 Gbps ROSA (Receiver Optical Subassembly) is an optical 6-pin receiver unit
which is designed for 10 Gbps transmission. Two versions are available:
a) The XMD single mode type which is optimized for OC-192/STM-64 and 10GbE applicatioins.
b) The XMD LRM type which is designed for the 10GbE LRM transmission.
The ROSA contains a high-speed PIN photodiode and a low-noise linear trans-
impedance amplifier in a hermetically sealed ROSA. A flexible-printed-circuit (FPC)
can be added to deliver impedance controlled high-speed outputs. The mechanical
outline and the FPC provide XMD-MSA compliant interfaces to the PCB and housing
and allow for easy use in product design and manufacturing.
