Model 755MM-X Optical Transmitter

DWDM, 65 km, Low Distortion

Emcore’s Model 755MM-X is a directly modulated (DM) DWDM optical

transmitter specifically designed for CATV transmission over fiber links

up to 65 km.

The 755MM-X supports full 79-channel NTSC analog signal carriage

with RF bandwidth up to 870 MHz. The 755MM-X supports dual power

supplies as well as the SNMP network interface protocol.

The 755MM family of transmitter products is designed to support various

CATV transmitter applications with a common platform. Integrated within

the transmitter design are Emcore’s low chirp control, noise suppression

circuitry, and patented predistortion technology to provide outstanding

performance with any of Emcore’s wide range of cooled broadband

lasers.

Applications

ꢀVideo signal distribution to

HFC CATV and FTTP nodes

ꢀVideo overlay in passive

optical networks

The 755MM-X incorporates the Hybrid Modulation^TM(patent pending)

scheme to enable the performance of externally modulated transmitters

with the ease of tuning directly modulated transmitters.

Absolute Maximum Ratings

PRELIMINARY DATASHEET| JUNE 17, 2007

Stresses in excess of the absolute maximum ratings can cause permanent damage to the transmitter. These are absolute stress ratings

only. Functional operation of the device is not implied or guaranteed at these or any other conditions in excess of those given in the

operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device

reliability.

1. SBS threshold is measured on the basis of noise floor increase of 1 dB versus optical launch power at constant optical receiving power.

2. In order to prevent reflection-induced distortion, the laser must be connected to an optical cable having a return loss of at least 55 dB for discrete

reflections and 30 dB for distributed reflections.
