| 摘要 |
The invention concerns a method of connecting a subscriber unit ( 12 ) to a fiberoptic communication network ( 14 ) via a fiberoptic interface device ( 30 ) adapted to function as an interface device ( 30 ) in a coarse wavelength division multiplex (CWDM) system. The interface device ( 30 ) comprises an electric circuit arrangement ( 32 ) and a first ( 34 ) and a second ( 36 ) receiving section adapted to receive transceiver modules ( 24, 70 ). According to the method, an opto-electric transceiver module ( 24 ) is arranged in said first receiving section ( 34 ) and connected to said fiberoptic communication network ( 14 ). A first electric transceiver module ( 70 ) is provided and arranged in said second receiving section ( 36 ). The interface device ( 30 ) is connected, via said electric transceiver module ( 70 ), to said subscriber unit ( 12 ) via electrical conduction paths ( 82, 86 ). The invention also concerns a method of testing the function of said interface device ( 30 ).
