Pump Laser, 9xx, 4 W, Uncooled, Multi-Mode

The JDSU 4800 Series 915 nm and 939 nm uncooled multi-mode pump modules simplify next-generation high-power erbium doped fiber amplifier (EDFA) designs for CATV and FTTx applications by eliminating the need for larger, less efficient, and costlier thermoelectric coolers and their control circuitry.

The 4800 Series single-emitter fiber-coupled laser diodes offer up to 4 W power from a 100 μm fiber into 0.2 NA in an operating temperature range of -5 to 70 °C.

The 4800 Series pump module incorporates the JDSU 6390 laser diode for unmatched performance and reliability at high temperatures and power levels. Leveraged from the single-mode 980 nm telecom design, this package shares the same field-proven L3 platform and demonstrates excellent long term reliability.

The 4800 Series pump module is tested to Telcordia GR-468-CORE and meets the intended requirements of this telecommunication components standard.
