MSTP transmission platform

Distance of 1310nm CWDM SFP+ transceiver and 1550nm CWDM SFP+ transcveiver:
[1] based on SDH multi-service transport node, in addition to have the function of the standard SDH transmission node, but also has the following main functional characteristics.
(1) TDM services, ATM services or Ethernet access capabilities;
(2) TDM services, ATM services or Ethernet service delivery features include point-to-point transparent transmission function;
(3) ATM services or Ethernet bandwidth statistical multiplexing function;
(4) ATM services or assigned functions Ethernet services mapped to the SDH virtual containers.

MSTP based on SDH multi-service transmission node can be applied in the transport network access layer, convergence layer according to the network needs, but applied in the backbone layer is to be studied.
MAN is the focus of telecom operators compete for a wide range of metropolitan area network technology, generally including the SDH structure-based metropolitan area network, Ethernet structure based metropolitan area networks, ATM structure based metropolitan area network, and DWDM structure based metropolitan area network. In fact, SDH, ATM, Ethernet, WDM and other technologies are continuing to draw on the strengths of other technologies, learn from each other, it is necessary to achieve rapid transmission, but also to meet the multi-service bearer, and provide carrier-class QoS, all kinds of showed a trend of convergence between the MAN technology.

Important reason for the optical module functional failure

1. Optical Interface is polluted and damaged.The pollution and damage of the optical interface causes the optical link loss become large, resulting in the optical link fails. Reason as follows:A. The interface is explored in the environment so that the dust pollutes the interface.B. The fiber connector which is used has been polluted so that it causes the secondary pollution.C. Improper use of the interface of the optical connector with pigtail. D. The use of poor quality fiber optic connectors. 2. ESDM damageESD is the abbreviation of Electro Static Discharge.  ESD can produce tens of kv/m of electromagnetic pulse and even more.Static electricity will absorb dust, changing impedance

Compatibility verification

Compatibility verification is the analysis of the modules' work environment to meet the data sheet or compatibility and related standards. The performance of the module only in this compatibility work environment can be guaranteed. In some cases, due to environmental parameters beyond the data sheet or standard, it will cause the module performance degradation, thereby transmission error. Work environment and the module are compatible: 1) Voltage outside the specified range;2) Received optical power overload or lower than the receiver sensitivity;3) The temperature is outside the operating temperature range. SOPTO’s high quality fiber optic transceiver modules are 100% compatible with

Development Trends of Fiber optic transceiver

The fiber optic transceivers in continuous development and improvement of the equipment also raised many new requirements. First, the fiber optic transceiver product is not enough intelligence. For example, when the optical fiber transceiver broken, the mouth the other side of the power of most products will still remain open, the top equipment such as routers, switches, etc. are still will continue to the electrical port contract, the data is not up . I hope the majority of equipment providers can automatically switch on the fiber optic transceivers, up alarm automatically when out of optical path DOWN, electrical interface, and to prevent the upper equipment to continue to the port to
