PTN solution
8/24/15  |  Technical Article  |  FiberOnSale.com

PTN packet transport product is designed, its main features is reflected in the following areas: flexible scheduling networking capability, multi-service transport capabilities, comprehensive carrier-class security, carrier-class OAM capabilities, with business sense and end service provisioning management capacity, low cost per bit transmitted.

PTN technology concepts
8/23/15  |  Technical Article  |  FiberOnSale.com

PTN technology is essentially a packet-based routing architecture to provide multi-service technical support. It is a more suitable for IP service transmission technology, while inheriting the traditional advantages of optical transmission, including a good network scalability, a rich operation and maintenance (OAM), fast protection switching and clock transmission capability, high reliability and safety sex, the whole concept of network management, end to end service configuration and precise alarm management. These advantages PTN is the traditional router and Enhanced Ethernet technology can not match, which is distinct from the important attributes of both. We can understand the concept of PTN technology from the following four aspects.

Including optical receiver module, optical transmitter module, optical transceiver module and optical transponder modules.

OADM technology and product development trends
8/19/15  |  Technical Article  |  FiberOnSale.com

Currently, reconfigurable OADM has become the development direction. In addition to using the optical switch dynamically select the upper and lower wavelengths, the use of a tunable filter is a hot spot.

OADM applications in all-optical networks
8/18/15  |  Technical Article  |  FiberOnSale.com

OADM equipment in long haul and metro networks are useless.
◆ In the trunk applications, OADM device of choice up and down business intermediate nodes.

OADM classification and characteristics
8/17/15  |  Technical Article  |  FiberOnSale.com

The main function of OADM is separated from the multi-wavelength channels or insertion of one or more wavelengths, there are fixed and reconfigurable two types.

T-MPLS technology Interpretation
8/16/15  |  Technical Article  |  FiberOnSale.com

T-MPLS (Transport MPLS) is a connection-oriented packet transport technology. In the transport network, the client signal is mapped into the MPLS frame and use MPLS mechanisms (such as label switching, the label stack) forwards, while it increases the basic functions of the transport layer, such as connectivity and performance monitoring, survivability (protection and restoration), management and control plane (ASON/GMPLS).

Narrowband PON technology features
8/14/15  |  Technical Article  |  FiberOnSale.com

Narrowband PON network topology and the same ATM-PON, which has the following major differences between ATM-PON:
◆ ATM-PON broadband access technology, can provide users with more than 2Mb/s access rate; narrowband access technology only supports narrowband service, to provide users with access speed of up to 2Mb/s.

ATM-PON technology features
8/9/15  |  Technical Article  |  FiberOnSale.com

The most important feature of ATM-PON, is its passive multipoint type network structure. It combines the ATM technology and passive optical network technology to provide a variety of services from existing narrowband to broadband. ATM-PON by the OLT, ONU / ONT and passive optical splitter components.
