Octal Optical S-1.1 Module
15.1 Functional Description of Module
The S1.1-8-LC module contains eight optical STM-1 interfaces that meet the S-1.1 specification in ITU-T G.957. The physical connector is an LC connector.
The module also contains 8 mapper circuits and an IP switch, allowing concentration of IP traffic mapped into a VC-12 container. Because the mapper circuits are connected to the matrix, the mapper circuits are global resources which means that the traffic to be terminated can come from other modules in the system.
As shown in Figure 15-1, the module is especially made for termination of traffic from a large number of ONS 15302 and ONS 15305 devices.

15.2 Power Consumption
The power consumption of the S1.1-8-LC is 25 W.
15.3 External STM-1 Interface
15.3.1 Description
The eight optical STM-1 interfaces use dual fiber interface, LC style connector, one fiber in each direction, 1310nm wavelength and use single mode fiber of type 10/125 um. The optical interfaces is compatible with ITU-T 957 for S-1.1.
The interface is an optical STM-1 short haul interface, according to clause 5 ITU-T G.957 The definitions of optical parameters and reference points S and R refer to ITU-T G.957. Reference point S means transmit direction while R is the receive direction of the fibre.
15.3.2 Connector Type
The physical connector is an LC connector.
15.3.3 Optical Budget
Table 15-1 describes the optical parameters.
