Fiber Optic Modules

This section lists the types of fiber optic modules supported on Foundry's FastIron stackable devices.
• 100BaseBX – Supported only on the FESX424HF, 100BaseBX uses single mode fiber for bidirectional
ethernet applications and supports Ethernet in the First Mile (EFM) applications. Its maximum distance is 10
kilometers.
Support for 100BaseBX was added in release 02.3.01 for the FESX424HF.
• 100BaseFX – Supported only on the FESX424HF, 100BaseFX is also known as the "fiber version" of
100BaseTX. 100BaseFX uses two strands of multi-mode fiber (MMF) for receive and transmit. Its maximum
distance is 2000 meters (2 kilometers).
Support for 100BaseFX was added in release 02.3.01 for the FESX424HF:
NOTE: You must enter a CLI command to enable and disable support for 100BaseFX on a fiber port. See
"Enabling and Disabling Support for 100BaseFX" on page 2-16.
• 1000BaseBX
• 1000BaseBX10-U – The EFM-U fiber (uplink) transceiver wavelength = 1310 nm (Foundry part number
E1MG-BXU). These optics are in accordance with the IEEE 802.3ah standard, Ethernet in the First Mile
(EFM).
Support for EFM-U optics was added in release 02.2.00 for the FESX and FWSX.
• 1000BaseBX10-D – The EFM-D fiber (downlink) transceiver wavelength = 1490 nm (Foundry part number
E1MG-BXD). These optics are in accordance with the IEEE 802.3ah standard, Ethernet in the First Mile
(EFM).
Support for EFM-D optics was added in release 02.2.00 for the FESX and FWSX.
• 1000BaseLH
• 1000BaseLX – 1000BaseLX uses long wavelength (LX) laser over multimode and single-mode fiber.
