This paper describes 2.8-Gbit/s, 5-channel optical transmitter and receiver modules for board-to-board interconnection in asynchronous transfer mode (ATM) switching systems. These modules are constructed of optical and electrical submodules. The optical submodule mainly consists of a multimode-fiber array and an optical device array. The electrical submodule is constructed by a multichip module technique with GaAs IC's and multilayer ceramic substrates. The advantage of the submodule fabric is that the submodules are independently assembled after testing. Error-free 250-m transmission is successfully demonstrated over a wide range of temperatures (from 25/spl deg/C to 60/spl deg/C), without automatic power control and automatic temperature control circuits in the optical transmitter module. >
