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. Single-strand SFPs can be used. These SFPs work in pairs and require a matching SFP at the opposite end of the Ethernet connection. For example, an SFP rated at TX 1310, RX 1550 must be paired with an SFP rated TX 1550, RX 1310 with the same maximum operating range. See the following corresponding table (Single-strand SFPs Pairing) for more information. For information about bandwidth and line rate considerations for the GE–HDE module combination, see GE-2 SFP I/O Modules Overview in the Configuring Ethernet Interfaces chapter of the JunosE Physical Layer Configuration Guide.
