ATOP 10 Gigabit per Second Transceivers

ATOP Technologies 10 Gigabit per Second Transceivers are Small Form Factor Pluggable (SFP+) transceivers compatible with SFF-8431 and SFF-8432. The 10 Gigabit per Second Transceivers are designed for use in 10G-Gigabit multi-rate links. The ATOP 10 Gigabit Transceivers support 10G Ethernet SR and 10G fibre channel. The Transceivers digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.
