 Single-mode fibers

Single-mode fibers (SMFs) have thinner fiber cores and can transmit light in only one mode.

Single-mode fibers suffer little intermodal dispersion and are suitable for long-haul communication.

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 Switches, the following fiber diameters are recommended:

 G.652 common single-mode fiber: 9/125 μm

 G.655 single-mode fiber: 9/125 μm

 Common multimode fiber: 62.5/125 μm

 G.651 multimode fiber: 50/125 μm (for multimode VCSEL laser)

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 Switches use the following types of connectors:

 Lucent connector or local connector (LC)

 Multi-fiber Push On connector (MPO)
