PDH(SCP-240) optic equipment

Detailed Product Description

1. Outline

Standard type:

SCP-240 series of standard type can whole transmit transparently 2M Quasi-synchronous based groups signals to achieve voice and data transmission operations.It delivers the capacity as 8 E1 access , and an additional 1 to 4 RS232 asynchronous data access and 1 PCM Official calls access off 2M access

Ethernet type:

The scp-240 series can provide ethernet
optical transmission system.It makes true the 8 E1 electric circuits and 1-2 100M speed ethernet data passages in mixed use and the optical transmission in a simple and direct and single plank form.
Two-fiber protection type:

The scp-240 series can provide two-fiber protection type optical transmission system that use optical road 1+1 backup protection, cut over lines automatically,reduce the postpone time because of breakdown.
Single-fiber type:

The scp-240 series can supply single-fiber type optical transmission system,integrated modular optical transceivers.It can use the resource effectively in case of the fibre resource in short supply.
