Fiber diameter
Fiber diameter is expressed as core diameter/cladding diameter, in μm. For example, 9/125 μm means
the fiber core diameter is 9 μm and the fiber cladding diameter is 125 μm.
For the HP Comware-Based devices, the following fiber diameters are recommended:
• G.652 standard single-mode fiber—9/125 μm.
• G.655 single-mode fiber—9/125 μm.
• G.651 standard multimode fiber—50/125 μm or 62.5/125 μm.
Connector
CAUTION:
Cover the connector with a dust cap when it is not connected to any optical fiber.
Connectors connect transceiver modules to the corresponding transmission media. The transceiver
modules available for the HP Comware-Based devices use the following types of connectors:
• Lucent connector or local connector (LC).
• Multi-fiber Push On connector (MPO).
