Huawei 03051266 MST4(1xFC SM 2km+2xESCON/DVB-ASI MM) OSN1500 4 ports board

Product Description:

• OptiX OSN equipment uses a universal switch architecture for unified grooming of packet services and TDM services. OptiX OSN equipment can work in packet mode, TDM mode, or dual-domain (packet+TDM) mode.The three modes can be smoothly switched by upgrading the software of a service board so carriers' requirements on services and networks can be met. The smooth switching between the three modes supports carriers' distributed smooth investment based on the development of the

technology and industrial chain.
Based on a universal switch architecture, OptiX OSN equipment uses the packet transmission
technology to perform efficient statistical multiplexing on data services so the transmission cost
of every bit is reduced. In addition, OptiX OSN equipment uses the Native technology to transmit
TDM services so voice services are transmitted with high quality.

Based on a universal switch architecture, OptiX OSN equipment unifiedly transmits packet
services such as 2G, 3G, and VIP private line services so network overlapping is avoided. In
addition, OptiX OSN equipment transmits TDM services. Carriers can constitute an end-to-end
packet network, dual-domain (packet+SDH) network, or hybrid (MSTP+routers) network that bears L2+L3 services. This complete packet transmission solution allows an evolution from TDM networks to all-IP networks.

• The OptiX OSN equipment uses the built-in WDM technology to transmit several wavelengths
over one optical fiber. In this manner, the OptiX OSN equipment can be interconnected with the
WDM equipment.
The OptiX OSN 1500 provides the built-in WDM technology. The functions of the equipment
are as follows:
• Standard DWDM wavelengths that comply with ITU-T G.694.1 can be added or dropped.
• Standard CWDM wavelengths that comply with ITU-T G.694.2 can be added or dropped.
• A set of equipment can be configured into an Optical Terminal Multiplexer (OTM) or an
Optical Add/Drop multiplexer (OADM), or both.
• Optical add/drop multiplexing boards have concatenation ports which can be used for
expansion or for adding/dropping multiple wavelengths through concatenation.
• The equipment supports Raman amplifiers which can be used in long-distance signal

transmission.
• The equipment supports the automatic gain control technology, which enables the gain of
each working wavelength to change within an allowed range in all scenarios.
• The equipment supports the forward error correction (FEC) technology, which can correct
the errors generated during signal transmission and therefore improve the tolerance of
signal-to-noise ratio at the receive end and extend the length of relay sections.
