IOA label | ES2-S3 GE-20 IOA |
Number of IOA ports | |
Software release | |
Description | - 92 W maximum
- Full-height module
- See Module and Slot Combinations for more
information on combining IOAs in a slot.
- Uses a range of small form-factor pluggable (SFP) transceivers
to support different modes and cable lengths
- Uses either optical or copper SFPs.
- The optical transceivers are 1000Base-SX, 1000Base-LX,
and 1000Base-ZX compliant.
- The copper transceivers are 1000Base-T compliant and require
a ferrite core to be attached around the Ethernet cable. Note that
a ferrite bead is not required for a Finisar transceiver (FCLF8522P2BTL–J1).
- 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.
- In a 100 Gbps fabric configuration, the E320 router can
accommodate up to 2 combinations of ES2 10G LMs and ES2-S3 GE-20 IOAs.
You must install a combination in either of the turbo slots (slot
2 or slot 4). The 100 Gbps allocates 10 Gbps of overall bandwidth
to each of these slots.
- In a 120 Gbps fabric configuration, the E120 router can
accommodate up to 6 combinations of ES2 10G LMs and ES2-S3 GE-20 IOAs.
You can install a combination in any of the line module slots, each
of which are allocated 10 Gbps of overall bandwidth.
- In a 320 Gbps fabric configuration, the E320 router can
accommodate up to 12 combinations of ES2 10G LMs and ES2-S3 GE-20
IOAs. You can install a combination in any of the line module slots,
each of which are allocated 10 Gbps of overall bandwidth.
