Description

STM-1 Optical/Electrical Converter

Introduce

Overview

SDH-EOC is an interface converter for STM-1 electrical and optical interface conversion.
It is designed for the SDH equipment coaxial interface and optical interface interconnect,
as well as the ATM 155.520 Mbps interface and SDH device interconnection.
Complete loop-back facility is supported for system diagnostic and commissioning. Compact casing and simple operation achieve the cost saving and investment protected.
STM1-EOC is the use of ASIC circuitry design technology developed, STM-1/OC3 high-speed fiber-optic modem, transmit the transparent unframed 155.52Mbps electrical signals by fiber optic cable, expanding the STM-1/OC3 transmission distance.
STM1-EOC transmission characteristics comply with ITU-T G.703/813/958 STM-1 standard.
STM1-EOC transmission characteristics comply with Bellcore SONET GR-253 standard.
STM1-EOC no need to do any complex settings, using simple, easy to operate.
STM1-EOC with complete diagnostic capabilities, can perform local analog loopback and local digital loopback.
STM1-EOC optical interface supports SC/ST/FC optional; SM/MM optional; WDM or normal;
Transmission distance can be 2Km/20Km/40Km/60Km optional. The product is fully compliant with FCC Part 15 requirements.
