On a branch card, users can flexibly configure port types. Such as mixing standard STM-1 electrical modules and optical modules; Hot swappable without affecting other interfaces. This allows for greater flexibility and investment savings in the configuration of daughter cards.
Flexible use of LTU. The branch card can be mixed with 1.5M or 2M (or 34M/45M) LTUs.
We can provide an integrated solution for transmitting PDH, SDH, and DATA services, reducing investment and saving space.
Supports chain, ring, star, and mesh network structures.
Support the application of TCM function in multi carrier networks.
Has a very high system redundancy design.
Support multiple protection mechanisms. Such as MSP, MS-Spring, SNCP, and EQP.
Marconi's network management ServiceON MV36/MV38 or LCT can provide scalable network management capabilities.
Can interconnect and communicate with existing products of SMA and MSH families.

summary:
SMA16-64 is a high-density product that reduces space occupation and power consumption while providing greater flexibility. The SMA16-64 multiplexer has line speeds ranging from STM-1 to STM-64.
According to different target markets, there are two types of shelves to choose from: standard and compact, optimizing investment and space utilization.
Two different sub racks can be assembled into three products: SMA16-64，SMA16-64c，SMA16-64ec。
The SMA16-64 family can be used as terminal, ADM, and DXC models for STM-1/4/16. And these multiplexers all use the same shelves and boards. In addition, SAM16-64 and SMA16-64c also support STM-64 line rates.

Business type
The SMA16-64 family can carry different network service data. In addition to standard SDH and PDH signals, it can also transmit/integrate/switch/aggregate 10/100M or Gigabit Ethernet.
SDH services: 155M, 622M, 2.5G, and 10G
PDH business: 1.5M, 2M, 34M, 45M, 140M
10/100M Ethernet， GE： Provide an effective and cost-effective solution for connecting IP devices.

safety
The design of SAM16-64 products meets European safety standards:
Electrical safety: EN60950 EN41003
Optical safety: Automatic light source cut-off procedure ITU-T G.664
Electrical products EN60825-2

mechanical structure
The subrack is designed as a single-layer structure with slots.
The standard sub frame size is 450mm (height) * 450mm (width) * 280mm (depth);
The dimensions of the compact subrack are: 450mm (height) * 450mm (width) * 280mm (depth).
These dimensions include LTU panels. Subracks can be installed in ETSI racks (ETS 300 119-3) or 19 "standard racks. Any subrack requires the installation of fan exhaust and fans.

electrical environment
The design of SAM16-64 product meets the EMC requirements of European standards:
ETS 300 386-2 CLASS B
EN 50081-1
EN 50082-1
EN 55022 CLASS B
