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).
