STM4 Ethernet transmission over SDH

STM4 Ethernet transmission over SDH
Product Detailed
1.Equipment could be inserted into 16 subsidiary cards. 2.Max bandwidth:252Mbps 3.Max Frame Size: 1536Byte Name: Ethernet transmission over SDH

Optical port is STM-4(622M).

Product Overview

1. Modular design and the controllable cost

2. One GE port and one GF port in the uplink to converge the isolated services mutually

3. 2*STM-4 optical port in the downlink, two power supplies, it’s safety and reliable

4. The high convergent proportion, the maximum convergence of  MOAP-EOP-622M(4U) are 252E1, with 16E1 as a unit realizing modular design.

5. Ethernet simultaneously combines GFP and HDLC encapsulation, so it can be connected with other protocol converters 

adopting GFP or HDLC encapsulation from any other manufacturers.

6. Support Ethernet anti-loopback test

7. The flexible choice for bandwidth, maintain the value of the equipment investment.

8. Support alarm shielding function

9. Support the powerful fault tolerance capacity

10. Support standard SNMP network management.
