Type 3 Media Filter
When connecting token ring devices that are not equipped with a
Type 3 Media Filter to a UTP port, a Type 3 Media Filter, such as the
Cabletron Systems TRMF or TRMF-2, must be installed in line with
the lobe cable at the connection to token ring station.
Multi-Mode Fiber Optic Network Requirements
When connecting a Fiber Optic Link Segment to TRRMIM-F2T or a
TPIM-F2, the following network requirements must be met:
• Cable Type - The cable must be one of the following multi-
mode fiber optic media:
-
50/125 m fiber optic cabling.
-
62.5/125 m fiber optic cabling.
-
100/140 m fiber optic cabling.
• Attenuation - The fiber optic cable must be tested with a fiber
optic attenuation test set that is adjusted for an 850 nm
wavelength. This test verifies that the signal loss in a cable is
within an acceptable level:
