JDSU Pump Lasers – High-Performance Optical Amplification for Fiber Networks
JDSU Pump Lasers are industry-leading laser diode modules designed to provide reliable and efficient optical pumping for Erbium-Doped Fiber Amplifiers (EDFAs), used in high-capacity telecommunication and data transmission systems. Renowned for their outstanding reliability, superior output stability, and long operational life, JDSU pump lasers are essential components in modern optical communication infrastructures.
Engineered with advanced semiconductor laser technology, JDSU pump lasers deliver consistent performance even under demanding conditions. These pump lasers play a vital role in enabling long-haul transmission, metro networks, and amplification systems by efficiently exciting the erbium-doped fiber, resulting in signal amplification without electrical regeneration.
Key Features of JDSU Pump Lasers
1. High Optical Output Power
JDSU pump lasers are available in multiple output configurations such as 120 mW, 180 mW, and 200 mW, catering to a range of amplification needs. The high optical power ensures maximum efficiency in erbium fiber excitation and superior amplification over long distances.
2. Precision Wavelength Control
Operating at a wavelength of 976nm or 980nm, JDSU pump lasers offer excellent compatibility with standard EDFA systems. The narrow wavelength tolerance ensures optimized gain in the EDFA process, enabling clear and consistent signal amplification.
3. Advanced Fiber-Coupled Design
These pump lasers feature a fiber pigtail output (typically SM or PM fiber) with angled or flat cleaves. This fiber-coupled architecture reduces signal loss, enhances beam quality, and simplifies integration into optical amplifier modules.
4. Compact and Durable Package
JDSU pump lasers are available in Butterfly 14-pin packages or miniaturized pump modules. The compact size allows for easy integration into a variety of telecom systems and modules, while the robust build ensures durability in field environments.
5. Internal Thermoelectric Cooling
Each module includes an integrated Thermoelectric Cooler (TEC) and thermistor for temperature regulation, allowing the laser to maintain optimal performance and wavelength stability across varying ambient conditions.
6. Long Operational Lifetime
JDSU pump lasers are known for their exceptionally long MTBF (Mean Time Between Failures), often exceeding 100,000 hours. This makes them ideal for mission-critical telecom operations requiring 24/7 uptime.
