GE High Density (HDE) Module Combination (2 Ports)

Line module label	GE-HDE
I/O module label	GE-2 SFP I/O or 2XGE APS I/O SFP or GE-2 APS I/O SFP
Number of I/O ports	2 active, 2 redundant
Software release	First supported: 7.0.0 Final supported: Not applicable
Description	100 W Gigabit Ethernet The I/O module uses a range of small form-factor pluggable (SFP) transceivers to support different modes and cabling distances. Uses either optical or copper SFPs. The optical transceivers are 1000Base-LX/LH compliant. The copper transceivers are 1000Base-T compliant. For information about bandwidth and line rate considerations for the GE–HDE module combination, see GE-2 SFP I/O Module in JUNOSe Physical Layer Configuration Guide, Chapter 5, Configuring Ethernet Interfaces.
