Config. Dwg.
Diagnostics:
The 907-GBE (Gigabit Ethernet) media converter shown in Figure 4-6 is used to convert a single channel of
10/100/1000 Mbps Ethernet data into optical format at the remote end and vice-versa at the console end.
Regardless of the input data rate, the optical link always runs at 1000 Mbps (1250 Mbaud). This "switchless"
media converter supports jumbo frames and non-standard frames often used by multibeam sonars
(e.g. Reson 7125) and other proprietary data links.
Auto-negotiation is supported, but can be bypassed if connecting to another device which does not support
auto-negotiation. MDI/MDX crossover handling is also supported on the RJ-45 port. The physical layer
interface also minimizes latency.
The 907-GBE cards are available in pressure tolerant versions with a 6000 psi rating.
