OPTICAL SIGNAL CONNECTIONS

For details about link operation, see sections 4.1 and 4.2.

2.2.1. Single Fiber Version

FIBER I/O: This is the optical input/output of the single-fiber 7707MT-HD version of the module. The
connector is a female SC/PC (shown), ST/PC, or FC/PC connector as specified at the time
of purchase. This input/output should be connected to the FIBER I/O connector of a
companion single-fiber 7707MT-HD module with a suitable fiber optic cable.
Single-fiber versions of the 7707MT-HD are designed to work with single-mode fiber optic
cable. Single fiber 7707MT13-HD versions use 1310nm wavelengths. Single fiber
7707MT15-HD-W versions transmit and receive on 1550nm and 1310nm wavelengths
respectively.
Note that while the optical input to the companion 7707MR-HD is invalid (i.e. not
connected) then the optical output of the companion 7707MR-HD will also be invalid. This
will result in a LINK...LOS condition (section 4.2.1) at the optical input of the 7707MT-HD
The optical output of the 7707MT-HD can be configured to operate in continuous or
discontinuous mode as described in section 4.2.8. If discontinuous mode is selected, while
the video input to the 7707MR-HD is invalid (VID...LOS condition, section 4.2.1) then this
optical output will be disabled. If continuous mode is selected, then a valid optical video
output will be maintained.

2.2.2. Dual Fiber Versions

FIBER IN: This is the optical input to the dual-fiber 7707MT-HD-F2 version of the module. The
connector is a female SC/PC (shown), ST/PC, or FC/PC connector as specified at the time
of purchase. This input should be connected to the FIBER OUT connection of a companion
dual-fiber 7707MT-HD-F2 module with a suitable fiber optic cable. The dual fiber 7707MT-
HD-F2 version accepts input wavelengths from 1270nm to 1610nm, accommodating
standard, CWDM or DWDM transmission schemes. When connected directly to a
companion dual-fiber module, the 7707MT-HD-F2 is compatible with multi-mode fiber optic
cable. If not connected directly (i.e. connected through CWDM, DWDM, WDM, or
splitter/combiner) the 7707MT-HD-F2 is compatible only with single-mode fiber optic cable.
Note that while the optical input to the companion 7707MR-HD is invalid (i.e. not
connected) then the optical output of the companion 7707MR-HD will also be invalid. This
will result in a LINK...LOS condition (see section 4.2.1) at the optical input of the 7707MT-
HD.
