2.1.1. Single Fiber Versions
FIBER I/O:
There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical
input/output for the 7707IT-8 and 7707IT-3 (single fiber) versions. This connector should be
connected to the matching connector of a matching single fiber 7707IT module at the
destination end with a suitable fiber optic cable.
All single fiber versions of the 7707IT are designed to work with single-mode fiber optic
cable. Single fiber 7707IT-3 and 7707IT-8 versions use 1310nm wavelengths. Single fiber
7707IT-3-W and 7707IT-8-W versions use 1310nm or 1550nm wavelengths and have their
associated transmit wavelength marked on the rear panel.
2.1.2. Standard Dual Fiber Version (-F2 version)
FIBER IN:
There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical input to the
module. This connector should be connected to the FIBER OUT connector of a matching
dual fiber 7707IT-F2 module at the destination end with a suitable fiber optic cable. The
dual fiber 7707IT-F2 versions receive on wavelengths in the 1270 to 1610nm range
accommodating standard, CWDM or DWDM transmission schemes.
FIBER OUT:
There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical output
from the module. This optical output is available in 1310nm, 1550nm, and up to sixteen
CWDM wavelengths (ITU-T G.694.2 compliant). This connector should be connected to the
FIBER IN connector of a matching dual fiber 7707IT-F2 module at the destination end with a
suitable fiber optic cable. The dual fiber 7707IT-F2 versions transmit on the wavelength
marked on the rear panel and are designed to work with either single-mode fiber optic
cable. The dual fiber 7707IT-F2 versions are compatible with multi-mode fiber when
connected directly to a companion 7707IT-F2 module.
