CHAPTER 1. GENERAL INTRODUCTION
1.1 Product Description
8E1 + 1Ethernet Fiber Optical Multiplexer can multiplex to 8 E1 signals for transmission
over an optical fiber, resulting in reaching a longer distance without a repeaters and superior
performance compared to copper media.
8E1 + 1Ethernet Fiber Optical Multiplexer is the 8E1 point-to-point optical transport
equipment that uses the FPGA chips and it is easy to upgrade. It is single board structure
and the largest transmission capacity is 8E1. The outer design use the standard 19 inches
rack, so the volume is little, weight is light and operation is convenient and credit.
8E1 + 1 Ethernet Fiber Optical Multiplexer uses the PDH fiber transmission technologies.
The 2Mbps (E1) interfaces can connect with the exchanger, light loop device and
multi-diplexer directly to the special network. Complete alarm function for 8E1 Fiber Optical
Multiplexer, it is stable and easy to maintenance, install and small in size. It has one digital
service telephone.

1.2.1 Description
Device adopts veneer structure, and can be distinguished according to the functions into 5
parts: A. 2/8 combine unit, B. encode/decode unit, C. hot line unit, D. monitoring system, E.
second power. A, B and E are the basic parts, achieving reverse conversion from 4
2048kbit/s signals to laser signal. C and D are of assistant.
1.3 Characters
•Base on IC of independence intellectual property rights
•Adopt veneer structure
•Offer 1-8 × 2Mb/s digital interfaces
•Up to 8 E1 links on one fiber
•One link to service telephone for duty contract
•Provides 1 channel of 10M/100M, support VLAN setting.
•One channel OA for optional.
•When fiber signal is loss, users can distinguish whether the remote device is power
off or the fiber line is down from the indicator status on the local device.
•180-260VAC & -48VDC power options and the positive and negative of DC-48V can
be optional because there is the self-test circuit for the polarity inside th1e device
•Standard 19 inches rack, little volume, light weight, steady capacity and convenient
setup
