The unframed
The unframed E1 to fiber converter provides one E1 interface and one optical interface, enabling interface conversion between E1 and optical signals.
In unframed mode, users can utilize a data channel speed of 2.048Mbps. The device has a built-in loopback testing feature, facilitating engineering provisioning and routine maintenance.
● The E1 to fiber converter simultaneously supports adaptive 120Ω/balanced and 75Ω/unbalanced impedance, eliminating the need for manual configuration.
● The system has undergone rigorous testing and practical validation, fully complying with ITU-T recommendations such as G.703 and G.704.
● 3 loopback functions: optical loopback, E1 local loopback, and remote E1 loopback.
● Peudo-random code testing function (PATT), equivalent to a built-in error detector, facilitating line provisioning testing.
● Optional power supply options include AC 220V, DC -48V, and DC +24V, with no polarity distinction for DC power supply.
