The optical transmitters are high-performance 850 nm VCSELs. The optical receivers consist of GaAs PIN assemblies and preamplifier and post-amplifiers. The optical interface to the Sabre series Ethernet optical media converters is a Souriau ELIO connector, enabling interconnection to ELIO pre-terminated fiber optic cable assemblies. The electrical interface to the Sabre series optical media converters is a 12-position contact cover that facilitates interconnection to printed circuit boards, backplanes, or flexible printed circuit boards.

The transmitter's input lines are controlled by differential CML, LVDS, or LVPECL signals applied to the transmit pins (TX+ and TX-). The optical receivers consist of PIN assemblies and preamplifiers and downstream amplifiers with limiting. The electrical outputs from the receivers consist of differential CML, LVDS, or LVPECL data signals on the receive pins (RX+ and RX-) and single-ended CMOS or LVPECL signal detection functions with output attenuation on the signal detection (SD) pins.
