Components Components Specifications1 Ordering Information1 1480/1550 Pump Coupler DiCon's 1480/1550 Pump Coupler is constructed using DiCon's Cylindrical Filter WDM packaging technology. The Pump Coupler uses a thin film filter mounted between a pair of GRIN lens collimators. DiCon's 1480/1550 Pump Coupler is housed in a compact, environmentally stable package that offers superior resistance to humidity and temperature and is suitable for mounting on a printed circuit board or within a fiber amplifier module. 0.4 dB typ., 0.55 dB max.
