SFOR Forward path optical receiver

At an HFC hub is a common role to realize optical-RF conversion in order to manipulate the spectrum (e.g. inserting a local program). The SFOR does this with a user set constant output level. Two units can be configured for handling two independent optical signals with the same modulation content and only one RF output, i.e. an optical AB switch for redundant work is reachable. All these features are available in the general COMTECH headend style with local management interface and RF testpoint on the frontal surface.
