More details

16E1 10/100M ethernet PDH multiplexer:PDH-16L

PDH-16L  is a kind of fiber-optic communication device which can use fiber to transport 1~16 E1 signal in the meantime efficiently and can test the used E1 automatically. The flexible circuit test and the indication function has a simple single panel form, which provides 1~4 10M/100M Ethernet ports(optional) and a office phone port (optional), raising applied flexibility also in the meantime enlarge the utilization of the fiber optic.
    The four Ethernet ports are switching interfaces, 10M/100M self-adapting completely.


1.Base on IC of independence intellectual property rights
2.Adopt veneer structure
3.Offer 16 ×2Mb/s digital interfaces
4.Up to 16 E1 links on one fiber
5.Provides 1~4 Ethernet ports, support 10M/100M self-adapting, support VLAN.
6.One channel OA for optional.
7.180-260VAC & -48VDC power options and the positive and negative of DC-48V can be optional because there is the self-test circuit for the polarity inside the device
8.Standard 19 inches rack, little volume, light weight, steady capacity and convenient setup
9.Supports SNMP management.
