Supplied accessories Rear connector assembly.
Ordering IRT-6630-DDT IRT-6630-DDT, fitted with standard 1310nm laser, programmed with
DashBoard™ control.
IRT-6630-DDT/xxxx IRT-6630-DDT, fitted with CWDM DFB laser other than 1310nm where
xxxx = wavelength required.
For example, IRT-6630-DDT/1550 is an IRT-6630-DDT fitted with a 1550nm laser.
IRT-6630-DDR IRT-6630-DDR, fitted with APD detector, programmed with DashBoard™ control.
NOTE: 2 Typical values based using DFB laser. Optical attenuator supplied for
IRT-6630-DDR when optical path loss is less 9dB for APD detector.
Due to our policy of continuing development, these specifications are subject to change without notice.
