Short answer: reduce the gain, possibly using a multistage amplifier rather than a single stage amplifier.
Long answer: a more logical approach is to choose an appropriate device for the task. If you are trying to design a USB transceiver, I would first ask you why you are using an operational amplifier (i.e. a linear device) as the front-end to a differential transmission line carrying a NRZ-I encoded bitstream? There are many very cheap off-the-shelf ICs which will do exactly what you want. If you are trying to design your own from scratch, you probably need to do some research on line driver/receiver frontend design. An op-amp is not a very good choice here.
I agree with Daniel Robert Franklin. Reduce the gain if you need to use this op-amp (As the product gain*bandwidth is constant) or, preferably, choose a better op-amp.
Another possibility is to use a current feedback amplifier (CFA). The architecture of CFAs avoids the gain-bandwidth trade-off that comes with conventional operational amplifiers.
In addition to the answers given above, I would advise trying to minimise any stray capacitances in your circuit and layout, as these will ruin your high-frequency response.
Another possibility is to use a voltage feedback amplifier based on current feedback amplifier (VFA based on CFA). Dynamic properties are the same as the CFA, but both inputs are high impedance - as in classic VFA.
Otherwise, it would probably be appropriate to talk about increasing the bandwidth of the amplifier (with operational amplifier) than about increasing the bandwidth of the operational amplifier itself - although there is a clear link.
The best way to increase the bandwidth of an opamp is by decreasing the closed loop voltage gain of opamp.
Explanation: Opamp has a very low bandwidth(around 5Hz) and to increase the bandwidth, we apply negative feedback which decreases closed loop gain. Since gain*bandwidth=constant, so bandwidth increases in case of negative feedback.
Reducing the closed-loop gain is the way of improving bandwidth. Cascading can be taken into consideration but need to adjust the feedback register in each and every stage. Otherwise, with the same consideration, the cascade will reduce the bandwidth.
