FMUX04 là modem quang 4 cổng E1, khoảng cách quang 30km, đầu quang SC, nguồn 220VAC hoặc -48VDC
Sơ đồ ứng dụng
The FMUX04 is a multiplexer for four (4) E1 or T1 (selectable) transmissions over a single fiber optic link. Its half-rack format makes it ideal for low cost multiplexing applications that require up to four (4) channels. All channels provide completely transparent transmission of E1 or T1 regardless of frame mode, clock source or timeslot assignment. Available in either AC or DC models, the AC supplies operate from 100~240VAC while DC supplies operate from 18~72VDC. Additional options include “Order Wire” phone connection (FXS port) and an SNMP option. |
