The IDM NTD4102 Telephone Optical Terminal is a desktop-type multi-service fiber optic communication device with the following features:

Dual optical port design, supporting ADM chain network functionality. SFP optical modules allow convenient selection of single-mode/multi-mode, single-fiber/dual-fiber, wavelength, transmission distance, and other parameters.

2. The optical terminal supports transmission of two physically isolated Ethernet channels over fiber (by default, 100M is shared over fiber; VLAN partitioning between Ethernet interfaces is available upon request at the time of ordering, and the optical module will also differ).

The optical terminal supports transmission of two physically isolated Ethernet channels over fiber (by default, 100M is shared over fiber; VLAN partitioning between Ethernet interfaces is available upon request at the time of ordering, and the optical module will also differ).
The IDM NTD4102 optical terminal can provide 2 channels of RS485 transparent transmission (this configuration is not included by default and must be specified when ordering).
The IDM NTD4102 optical terminal can be used in point-to-point mode, and the timeslots for 10 telephone channels can be selected via DIP switches.

5. The IDM NTD4102 optical terminal can provide 1-4 channels of serial server plug-in cards, aggregated at the central end through the first network channel.

The IDM NTD4102 optical terminal can provide 1-4 channels of serial server plug-in cards, aggregated at the central end through the first network channel.
This optical terminal is powered by a default +5V power supply with an external AC220V power adapter, and can also support +24V and -48V power inputs upon request.
This optical terminal supports bidirectional dual signaling and telephone polarity reversal functionality. It also supports elevator intercom interfaces.
