The passive wavelength division multiplexing equipment is composed of a multiplexer and a color optical module. By using wavelength division multiplexing technology, optical signals of different wavelengths are combined on an optical fiber for transmission, thereby saving optical fiber resources. It has the advantages of fast deployment, small size, low power consumption and low cost.
With the rapid development of telecommunication and data services, the optical fiber resources in the network cannot meet the demand, and the optical cable has a long laying time and high costs. SONT passive WDM equipment realizes the multiplexing of the original optical fiber cable through the wavelength division technology, realizes a single optical fiber transmission multi-channel service, and can be applied to scenarios such as network expansion and upgrade and mixed transmission of various types of signals, such as wireless network upgrade and wireless indoor coverage system.
1、Support comprehensive access of wireless forward transmission and other services, take into account the bearing of wireless forward transmission, dedicated line and home wide services, and maximize the value of the forward transmission network;
2、The fiber can be saved to the maximum extent. One core fiber can carry multiple 4G and 5g forward CPRI / ecpri services;
3、The office end is active and the remote end is passive. WDM technology is used to expand the physical channel of pure transparent transmission, without introducing delay and jitter;
4、Support CWDM \ mwdm \ lwdm \ DWDM and other service wavelength division cards;
5、It provides monitoring of the operation status of the main line and channel branch of the combined and split wave, and can provide fault location monitoring. Locate the fault point through fault dyeing function; Easy maintenance and fault location;
6、Mwdm / lwdm supports OAM message reporting to semi-active network management;
7、Support optical layer 1:1 protection, and the protection switching time is less than 50ms to improve network reliability;
8、The optical layer protection function board can be selected according to the application scenario, and supports hot plug, power down / power on maintenance functions to ensure that the equipment will not affect the business operation in the case of power down;
9、The device network management supports SNMP, NETCONF and other protocols, and provides GUI Graphical user interface. The client adopts HTTP based Java Web Start client technology, and can start the management interface from the browser;
10、The active equipment at the office end supports AC 220V and dc-48v power supply options, and 1 1 power input protection;
11、The installation mode is flexible. The equipment at the office end supports rack type installation and wall mounting, while the equipment at the remote end supports rack type, holding pole and wall mounting. The installation is simple and plug and play;
12、The remote outdoor equipment meets the requirements of IP67 standard and supports the installation of holding poles and wall hangers.
