The invention relates to an arrangement for controlling the bandwidth in equipment for transmitting via single-mode connections between equipments regardless of their signal format. The arrangement comprises a transmitting channel (1) and a receiving channel (2). The transmitting channel comprises a converter arrangement and a single-mode transmitter (6). The converter arrangement comprises an amplifier (5) and possibly a multi-mode detector (9). The converter arrangement converts an electrical signal or a multi-mode signal into a form which is suitable for feeding into the single-mode transmitter (6). The receiving channel comprises a single-mode detector (8) and a converter arrangement. The converter arrangement comprises an amplifier (7) and possibly a multi-mode transmitter (11). The converter arrangement converts the electrical signal from the single-mode detector into an electrical signal or a multi-mode signal. According to the invention, the transmitting and receiving channels comprise controllable filters (10) for controlling the bandwidth of the arrangement, which can be utilized in charging the customer. |
