The 2307LR is a fiber optic receiver in a revolutionary form factor. With the same diameter as a BNC connector, and overall length of 3.3" (85mm), the 2307LR is the smallest RF optical receiver in the industry. It accepts an optical LC connector input on one end, and provides an electrical output on the other.
The 2307LR attaches to the input of a device without any intermediate cabling required. This essentially offers direct optical input to the connected piece of equipment, without incurring the cost and rack space associated with using conventional optical receivers. The primary application is in providing direct optical inputs to XRF series routers, without requiring external fiber receiver cards.
The 2307LR receives its power from the same connector that attaches to the input of the companion device, therefore the 2307LR may also be interfaced to any device that provides LNB voltage at its RF input connector. For example, when connected to a 7703DA16-RF-LNB, a fiber receiver with 16 electrical outputs is created. A 2307LR connected to the input of a 7703PA-LNB results in a fiber receiver with a high-powered output and adjustable slope compensation. The 2307LR may also be connected to the DC-biased inputs of devices such as IRD's, facilitating direct optical input via high-performance optical infrastructure.
