Network diameter should not exceed 512 bit-times (64 bytes) to ensure the collision detect mechanism operates correctly (14 bytes header, 46 bytes data, 4 bytes CRC). This includes repeater hops and propagation delay. For a bit more detail, search G0ogle books: 802.3 network diameter. The Network Consultant's Handbook should pop up... probably page 66.
