1. Overview

1.1 About This Manual

This instruction manual is a complete guide to install and operate the (1RU)

OTM-1550L optical transmitter. Please read the entire manual before beginning

installation.

This manual applies to OTM-1550L optical transmitter.

• Chapter 1 gives general information about the OTM-1550L optical transmitter.

• Chapter 2 describes the complete technical specifications of OTM-1550L.

• Chapter 3 describes the front/rear panel interfaces and menu system.

• Chapter 4 tells you how to install OTM-1550L optical transmitter.

• Chapter 5 tells you the communication setting of OTM-1550L.

• Chapter 6 describes maintenance and what to do in the event of problems.

1.2 Product Description

OTM-1550L intelligent directly modulated optical transmitter is mainly used in

1550nm optical fiber transmission system. Adopt advanced electronic dispersion

compensation technology, accurately compensate according to the actual transmission

distance by 1km stepping. The maximum compensated distance up to 50km.

OTM-1550L intelligent directly modulated optical transmitter is the most

important equipment to construct the CATV network. It mainly used for the

value-added services of TV image signal, digital television signal, telephone voice

signal and data (or compressed data) signal. By built-in WDM, multiplex the inter-cut

optical signal and the main optical signal then output. After setting required optical

difference, the perfect adjustable optical attenuation function can automatic control

the inserted optical signal according to the main optical signal, realize inter-cut system

full automatic adjustment. Provide high quality low cost solution for all-optical relay

1550 optical fiber CATV system, and local value-added services inter-cut.

Characteristics:

1. Patent pre-distortion circuit.

2. The optical fiber distance is adjustable according to the actual use condition by

1km stepping.

3. OTM-1550LⅡ: Built-in WDM, multiplex the inserted optical signal and the main

optical signal then output.

4. OTM-1550L Ⅲ: Built-in WDM and adjustable attenuator.

Model Selection:

OTM-1550L-I: standard 1550nm directly modulated optical transmitter, the default

optical output power is 10mW, and the optical output wavelength can choose ITU

standard wavelength.

OTM-1550L-II: on the base of OTM-1550L-I, add inter-cut function and built-in

WDM. The WDM specification please specify when ordering.

OTM-1550L-III: on the base of OTM-1550L-II, add VOA Variable Optical

Attenuator, can adjust the signal optical power intensity by the menu options on the

front panel.
