PDH fiber optical multiplexer DHODT-E+.
LCD PDH fiber optic multiplexer.
Modular integrated PDH fiber optic multiplexer DHODT-E+. Modular integrated optical transmission multiplexer with LCD Sreeen and SNMP.

Features:
1. Optical path backup: With the option of 1 + 1 optical redundancy (protection switching), in which the transmission automatically switches to a standby optical link in the event of a failure of the primary optical link; E3 or E6 switch or mandatory switch of optical path can be configured to meet requirements of network of high reliability

2. Network management: Furnished with network management interface (RJ45) that facilitates the realization of uniform network management

3. Easy to configure: Combination of main system board and various function modules can produce 4/8/12/16E1optical multiplexers and multiple optional traffic interfaces to meet requirements and customized demands of different users
4. Various function modules: User interface modules (N x 64K V. 35, V. 35, FXO/FXS, E/M, RS232/RS485); Service telephone module, network management module (RS422/485, RS232, 10baseT interfaces), RS232 data channel module, warning leading-out terminal module, switching value channel module

5. Complete functions of alarm indication: DHODT-E+ is capable of monitoring alarm status of local and remote equipment

6. Various functions of loop-back test: Each E1 channel can complete local and remote loop-back independently.

7. Transmission distance of 30 kilometers without relay (80-kilometer remote transmission equipment is prepared for your selection)

8. Modular and compact design of the complete appliance (19" 1U structure is used)

9. Convenient to extend capacity: DHODT-E has preliminary cascade interface, which facilitates cascading (equipment stacking) to optical multiplexer with higher E1 capacity when necessary.
