1. DESCRIPTION

This sheet is defining a target specification of OL5157M, which is a 1550-nm DFB laser diode

monolithically integrated with an electro-absorption (EA) modu lator for 40 Gb/s operation in a 7-pin

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

2. FEATURES

• High modulation bandwidth : > 32 GHz (- 3 dB electrical)

• Low modulation volta ge : < 2.5 Vpp

• Large dynamic extinction ratio @ 40Gb/s : 9 dB (typical)

• Fiber output power : > 5 dBm (CW)

3. APPLICATION

• 40 Gb/s very short reach (2 km) data communication

• 40 Gb/s NRZ / RZ medium and long reach trans mission
