1.DESCRIPTION
The OL2450L-3-Wnnn, OL2451L-3-Wnnn, OL2453L-3-Wnnn, OL3450L-3-Wnnn,
OL3451L-3-Wnnn, OL3453L-3-Wnnn, OL4450L-3-Wnnn, OL4451L-3-Wnnn,
OL4453L-3-Wnnn series consist of an MQW-DFB laser diode, a monitor PD, a single-stage
optical isolator, a single-mode fiber and a coaxial package.
These modules are coaxial DFB Laser Diode Modules for CWDM 2.5Gbit/s transmission
with high power at high temperature.
2. FEATURES
High output power: 3.0mW fiber output power under CW
Wide operating temperature range: Tc=0 to +70
°C
Side mode suppression: 32dB
Multi-quantum-well (MQW) DFB structure
Internal monitor PD for power control
Built-in single-stage optical isolator
Coaxial Package
No TEC required
