Noyes OTDR Fiber Boxes,1km, brand new, in stock. Noyes OTDR Fiber BoxesOTDRs require launch and receive test cables to measure the end-to-end loss of optical fiber links. A launch cable, which connects the OTDR to the link under test, reveals the insertion loss and reflectance of the near-end connection. A receive cable, which is connected to the far-end of the link, reveals the insertion loss and reflectance of the far-end connection. Noyes OTDR test cables are available in two forms. Fiber Boxes, which are available in standard lengths up to 1 km, are ideal for testing single-mode fiber spans (up to 50 km or longer) in Telco and Broadband networks. Please call or email for information about other length OTDR fiber boxes and Network Simulators, which are fiber boxes with customer-specified splices, connections, or other events.fiber boxes (FB) specifications

This will allow you to measure the loss of the near-end connection.• To use the Fiber Box as a receive cable, connect the Fiber Box to the far-endconnector of your fiber link under test. This will allow you measure the loss of the far-end connection.• By using Fiber Box as both launch and receive cables, as shown in the diagrambelow, you can measure total insertion loss of the fiber link under test.
