OC3/STM1 GE/FE
OC3-2 GE APS I/O
3; one active and one redundant port per SFP
Ports 0 and 1—ATM interfaces
Port 2—GE interface
Port redundancy is not supported.
First supported: 6.1.0
Final supported: Not applicable
150 W
Unchannelized OC3/STM1 ATM operation via two line interfaces
and
Gigabit Ethernet operation via one line interface
The I/O module uses a range of small form-factor pluggable (SFP) transceivers to
support different modes and cabling distances.
Depending on the configuration, a variety of SFP combinations can occur.
The OC3-2 GE APS I/O module accepts up to three LC-style fiber-optic or copper SFPs.
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 table (Single-strand SFPs Pairing) for more
information.
