* higher cost
* need for more expensive optical transmitters and receivers
* more difficult and expensive to splice than wires
* at higher optical powers, is susceptible to "fiber fuse" wherein a bit too much light meeting with an imperfection can destroy several metres per second "fiber fuse" detection circuitry at the transmitter can break the circuit and halt the failure to minimize damage.
* cannot carry electrical power to operate terminal devices (Note: current telecommunication trends greatly reduce this concern: availability of cell phones and wireless PDAs; the routine inclusion of back-up batteries in communication devices; lack of real interest in hybrid metal-fiber cables; increased use of fiber-based intermediate systems)
