DNC Loopback are used primarily as a means to test optical link in networks or devices by “looping back” the connections from the TX (Transmit) pairs to the RX (Receive ) pairs. By doing this , a complete optical link is formed , allowing the optical performance evaluation of a discrete component or complete link in a network path covering one or more interfaces.
DNC provides MTP/MPO loopback assemblies, which can pass rigid optical, mechanical, environmental test based on the GR-1435 requirements. And also complies with RoHS compliant.
