1550 nm 40 Gb/s EA Modulator Integrated DFB Laser
Rev. 2:[12. 2005]
Preliminary
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) modulator 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 voltage : < 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 transmission
