OC3/STM1 GE/FE Module Combination

Line module label OC3/STM1 GE/FE
I/O module label OC3-2 GE APS I/O
Number of I/O ports
  • 3; one active and one redundant port per SFP
    • Ports 0 and 1—ATM interfaces
    • Port 2—GE interface
  • Port redundancy is not supported.
Software release
  • First supported: 6.1.0
  • Final supported: Not applicable
Description
  • 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.
