design. Its function modules are independent of each other but easy for

assembly, which enables it to derive a series of optical multiplexer products

with multi-service interfaces. The equipment is furnished with four modular

User Manual Modular Multi-service Integrated Optical Transmission Multiplexer

slots. According to the networking requirements of different users, various

kinds of interface modules can be employed to accommodate to the

requirements of different application environments. The equipment also

provides four lines of .10M/100M self-negotiating Ethernet interfaces to

further satisfy the different user requirement.

1+1 Optical Redundancy Backup: Protection of dual optical interface

available to ensure that business will not be interrupted when one pair

of optical fibers is confronted with failure.

Flexible Configuration: 4/5/6/7/8E1 optical multiplexers and

multi-service interfaces are derivable from main system board and

different functional modules, to meet different user requirements and

customizations.

Various Functional Modules: User interface modules (E1, FE1, V.35,

FXO/FXS, and RS232/RS485, etc.), order wire module, network

management module, RS232 data channel module, alarm output

terminal module, and switch quantity channel module etc. available.

§2.2 Operating Principle

-s

adopts plug-in board structure and can be functionally divided into five

general parts, including:

A. Mainboard;

B. Optical interface;

C. Ethernet interface unit;

D. Secondary power supply;

E. Interface unit of other functions.

A. The mainboard is mandatory, which provides a platform for various

interface boards;

B. Either single optical interface or 1+1 redundancy optical interface

can be selected as required;

C. Despite the four lines of Ethernet interfaces, it also provides

network management and one line of user channel RS232, which can emit

overhead alarm signals;

Modular Multi-service Integrated Optical Transmission Multiplexer User Manual

D. Power supply unit, with different power supply modules to be

selected based on the power size.

E: various service cards/boards are optional as per actual requirement,

however, the total capacity shall not exceed 8E1.

This circuit integrates 4-8 2048kbit/s HDB3 signals from

switch or sent out by PCM, the four lines of Ethernet data, the one line of

standard deployed user channel signal and order wire alarm etc into one

NRZ digital stream signal, encode it and export a NRZ signal to drive the

laser, and achieves the reverse process for the above mentioned part at

the same time.

is to achieve the functions of 1+1 redundancy

backup of dual optical interface, priority-level switch, mandatory switch of

active/standby optical path, and so on. Switching mode for dual optical

interface: Dual transmission with optimal reception; Switching time for

optical pass: ≤ 50ms; Type of optical pass: One active and one standby

(the active pass is in operation when it’s normal, and the active pass

switches to standby pass when it is confronted with switching alarm levels

such as OPL, SYL, E3, and E6; The operation will finally return to the

active pass after a certain period of time when active pass is resumed to

normal condition); When the equipment is started, it is more advised to

have both local end and remote end operate in theA optical interface.

The optical interface applies an optical transmitting/receiving

integrated module of impact structure. It features high-power transmission,

high-sensitivity receiving and independent transmission and receiving.

provides four lines of Ethernet and one line of

232/485 network management interface, one line of data channel (RS232).

In addition, it can also provide overhead alarm signals from the network

management or the data channel.
