Noyes OTDR Fiber Boxes
OTDRs 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.
