Product Overview:

Lucent 248M 1480nm 50mw DFB Laser

The 248-Type DFB Laser is a precision, high performance, ultrahigh-reliability lightwave component that provides high output power light with wavelengths within the absorption band of an erbium-doped fiber amplifier (EDFA). The 248-Type Pump Laser Module is comprised of a CMBH multimode laser diode, CVD diamond subtnount, PIN backface monitor, micro­lensed single-mode fiber, and AT&T 100C output fiber pigtails,. all encased in a specially designed 14-pin butterfly package.

High Output Power, Ultra-High Reliability Pump Laser for EDFA

The 248-Type Pump Laser Module is capable of providing high output power in the 1470 nm to 1490 nm wavelength range for erbium-doped amplifier (EDFA) system application. The pump laser module is designed and individually certified for high-reliability operation and long-term life expectancy. The 1480 nm lnGaAsP laser chip utilizes a CMBH design with a CVD diamond submount for high performance and reliability. Chip and facet parameters are optimized for efficient pumping of EDFA. The laser package design includes a microlensed single-mode fiber and a planar lnGaAs PIN backface photomonitor assembled in a modular organic-free hermetic package. Laser welding technology is used for critical joints to achieve long-term stability. Each module is fully characterized and traceable. Long-life performance and reliability are ensured through extensive steps of burn-in, overstress, and power aging. The 248-Type Pump Laser Module is available with a typical power output range of 20 mW to 50 mW.
