OL5155M
1550-nm 40-Gbps EA Modulator with Integrated DFB Laser
DESCRIPTION
Oki's OL5155M is a 1550-nm DFB laser diode that is monolithically integrated with an electro-
absorption (EA) modulator. The OL5155M is designed for 40-Gbps operation and is available in a
7-pin package with a V-connector.
FEATURES
• High modulation bandwidth : > 30 GHz (- 3 dB electrical)
• Low modulation voltage : < 3.0 Vpp
• Large dynamic extinction ratio @ 40 Gbps : 10 dB (typical)
• Fiber output power : > 3 dBm (CW)
APPLICATION
• 40 Gbps very short reach (< 2 km) data communication
• 40 Gbps NRZ / RZ medium and long reach transmission
