Description: The polarization maintaining (PM) jumper (PM patch cord) is a PM connectorized polarization maintaining PM fiber. It can be supplied cabled in 3mm cable, 900µm tight buffer or loose tube, or bare fiber with 400µm coating. It features high extinction ratio as a result of very accurate active alignment between PM major axis and the connector key. Various PM fiber and connectors are available. |
