1.3.2 OPTICAL NETWORK INTERFACE SPECIFICATIONS
The Optical Network Interface is designated as ChA Tx, Ch A Rx, Ch B Tx, and ChB Rx on the
fiber optic module faceplate (see Figures 3, 4, 5, and 6). Phoenix Digital fiber optic modules are
compatible with either ST or SMA 905/906 style fiber optic connectors... as an ordering option
(mating connector which is terminated to the fiber media). (Alignment sleeves should be provided on
all SMA Style 906 connectors for optical alignment.) Detailed specifications describing optical net-
work transmit and receive capabilities at the 850nm multimode, 1300nm multimode, 1550 nm multi-
mode, 1300nm singlemode, and 1550 nm singlemode wavelengths are provided below:
