GigaPro features the ability to use a 2+0 link (two sets of links on the same path) to double the bandwidth without the use of an external switch.
2+0 Dual Modem Configuration – This is a double capacity link which utilizes two ODUs at each end of the link connected to a single IDU, combined on a single antenna (shown) or on separate antennas if desired. Each ODU pair forms a single RF link carrying up to 375 Mbps Full Duplex, for a total capacity of up to 750 Mbps Full Duplex.
- The Ethernet traffic is split between the two ODUs by the internal switch and then reassembled at the far end, enabling a single Ethernet port to be used if desired. Link aggregation mode is used to do this, with the hashing being done on both source and destination MAC and IP addresses. At least two flows to different MAC or IP destinations will be required to utilize the full capacity of the link.
- The 2 RF channels (F1 and F2) may be assigned in any frequency or polarization combination except on the same RF channel (co-channel). In addition, multiple channel bandwidths may be used if desired due to frequency congestion. Link reliability enhancement is in the form of hitless ACM on both active links, working independently such that frequency selective fading only affects one link. If one of the two links is disabled, the critical traffic is moved to the remaining link based on QoS rules.
- A license key is required to enable Modem 2 for two IDUs. Up to 4 ports of GigE copper, 32 ports of T1/E1 and 2 Optical ports (GigE fiber or STM-1/OC3) traffic may be used. (STM-1 and GigE Fiber ports are multiplexed)
- License keys are required for T1/E1 and STM-1/OC-3 operation
