2.1.2. Optical Signal Connections
For details about link operation, see sections 4.1 and 4.2.
2.1.2.1. Single Fiber Version
FIBER I/O: This is the optical input/output of the single-fiber 7707MR-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 7707MR-HD are designed to work with single-mode fiber optic
cable. Single fiber 7707MR13-HD versions use 1310nm wavelengths. Single fiber
7707MR13M-HD-W versions transmit and receive on 1310nm and 1550nm wavelengths
respectively.
The optical output can be configured to operate in continuous or discontinuous mode as
described in section 4.2.6. If discontinuous mode is selected, while the optical input to the
7707MR-HD is invalid (LINK…LOS condition, section 4.2.1) then this optical output will be
disabled. If continuous mode is selected, while the optical input is invalid then this optical
output will contain invalid information, but will still output.
2.1.2.2. Dual Fiber Versions
FIBER IN: This is the optical input to the dual-fiber 7707MR-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 7707MR-
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 7707MR-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 7707MR-HD-F2 is compatible only with single-mode fiber optic cable.
FIBER OUT This is the optical output of the dual-fiber 7707MR-HD-F2 version of the module. The
connector is a female SC/PC (shown), ST/PC, or FC/PC connection as specified at the time
of purchase. This optical output is available in 1310nm, 1550nm, and up to sixteen CWDM
wavelengths (ITU-T G.694.2 compliant). This output should be connected to the FIBER IN
connector of a companion dual-fiber 7707MT-HD-F2 module with a suitable fiber optic
cable. The output wavelength is marked on the rear panel of each 7707MR-HD-F2. When
connected directly to a companion dual-fiber module, the 7707MR-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 7707MR-HD-F2 is compatible only with single-
mode fiber optic cable. The optical output can be configured to operate in continuous or
discontinuous mode as described in section 4.2.6.
If discontinuous mode is selected, while the optical input to the 7707MR-HD is invalid
(LINK…LOS condition, section 4.2.1) then this optical output will be disabled. If continuous
mode is selected, while the optical input is invalid then this optical output will contain invalid
information, but will still output.
