SFM-1E, the multiplexer of the micro -SDH SFM-1E is intended for the extraction/of the insert of the channels Of [e]1 (2048[kbits]) beside the standard flow SDH STM-1. This SFM-1E compact (1U) SDH the multiplexer of the addition/of insert (ADM) with the optical interfaces on the front panel and the electrical interfaces on the back side; device can support from 8 to 42 low-speed [tributarnykh] interfaces Of [e]1. SFM-1E has two interfaces of level STM-1, on one down each direction (WEST-EAST). Interfaces are completely compatible with the standard ETSI and the recommendations ITU. All states of transfer and emergency are mapped onto the front panel

Device can be established beside standard 19” telecommunication cabinet. SFM-1E allows the powerful control capabilities, administration, of maintenance and the guarantees, such as: control besides reaction for the failures, monitoring of productivity, configuration and net safety.

Any SFM-1E can be [skonfigurirovan] as terminal multiplexer (ТМ), the linear multiplexer of the addition/of insert, or optical regenerator with the identical application. Furthermore, SFM-1E has the capability of the self-restored ring for increasing the reliability of network.
