TR-in-FE Cable Speciﬁcation

The TR-in-FE cable you connect to the TR-in-FE Module must conform to the Multi-Mode Fiber (MMF-PMD) standard deﬁned by ANSI x.3-166-1992.

3Com supports multi-mode ﬁber (MMF-PMD) 62.5/125 mm for full duplex mode. The maximum inter-station distance (including device-to-network connectors) should not exceed 2 kilometers (1.25 miles).

For half duplex mode, the cable length should not exceed 300 meters.

See the following table for cable speciﬁcations:
