OKI 1550nm 40Gbs EA Modulator Integrated DFB Laser NRZ SC/SPC Connector OL5157M

Descriptions
This sheet is defining a target specification of OL5157M, which is a 1550-nm DFB laser diode
monolithically integrated with an electro-absorption (EA) modulator for 40 Gb/s operation in a

7-pin package with a V-connector and a DC-bias circuit.

Features
• High modulation bandwidth : > 32 GHz (- 3 dB electrical)
• Low modulation voltage : < 2.5 Vpp
• Large dynamic extinction ratio @ 40Gb/s : 9 dB (typical)
• Fiber output power : > 5 dBm (CW)

Applications
• 40 Gb/s very short reach (2 km) data communication
• 40 Gb/s NRZ / RZ medium and long reach transmission
