GE2 1000Base-SX Module Combination (2 Ports)

Line module label GE-2
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: 5.3.0
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-SX 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 GE2 1000Base-SX module combination, see GE–2 SFP I/O Module in JunosE Physical Layer Configuration Guide, Chapter 5, Configuring Ethernet Interfaces.
