FEATURES
DESCRIPTION
The NDL7408P Series is a 1310 nm laser diode coaxial
module with single mode fiber. It has a strained Multiple
Quantum Well (st-MQW) structure and a built-in InGaAs
monitor photo diode. It is recommended for junction or access
networksystems. Theseriesisavailableintwotypesofoutput
power: 1.0 mW and 0.2 mW.
• CENTER WAVELENGTH
λC = 1310 nm
• TWO TYPES OF OUTPUT POWER:
1.0 mW (NDL7408PK Series)
