The JDSU 2700-TE Series 980 nm pump module features high kink-free powers up to 300 mW. It is packaged in a low-profile, epoxy-free, and flux-free 14-PIN butterfly planar package with fiber Bragg grating stabilization for wavelength locking. The module includes integrated thermoelectric cooler, thermistor, and monitor diode. It offers high dynamic range, excellent low power stability, and tight tracking of fiber-coupled power. The module meets the stringent requirements of the telecommunications industry and can be used in applications such as Erbium doped fiber amplifiers (EDFAs), dense wavelength division multiplexing (DWDM) EDFAs, and high bit rate, high channel count EDFAs.
The 2700-TE Series pump modules are 980 nm fiber Bragg grating‑stabilized lasers designed for EDFAs, DWDM, high‑bit‑rate amplifiers and CATV distribution. They feature a low‑profile, epoxy‑free 14‑pin butterfly package with integrated thermoelectric cooler, thermistor and monitor diode.
Key features include up to 300 mW kink‑free output, tight power tracking, and selectable peak wavelengths. The document lists absolute maximum ratings, operating parameters, electro‑optical performance, ordering codes, and safety precautions for handling the invisible laser radiation.
| Maximum output power | 300 mW |
|---|---|
| Fiber bend radius | 16 mm |
| Peak wavelength range (example code 27‑8000‑xxx‑TE) | 970.0 nm to 985.0 nm |
| Threshold current | 25 mA (max) |
Avoid looking directly into the fiber; the invisible laser radiation can damage eyes.
Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling the laser diode.
Peak wavelengths range from 970.0 nm to 985.0 nm depending on the product code.
