What Comtech FX Series WAN Optimization is
Comtech FX Series WAN Optimization is a self-hosted system for managing high-volume IP traffic, with a focus on satellite links across GEO, MEO, and LEO. It optimizes, compresses, bonds, balances, and prioritizes traffic to improve broadband quality of experience. A Protocol Enhancement Proxy operates at both ends of the link, while Turbostreaming accelerates file transfers and web browsing. The datasheet cites more than 150 Mbps per user TCP session and up to 600 Mbps for file transfer across 500 ms GEO links.
The system supports transparent Layer 2 and Layer 3 operation, VLAN and MPLS stacks, and L2/L3 VPNs, including overlapping IP address spaces. For mobile backhaul, it accelerates 4G/LTE and 5G traffic in GTP tunnels and handles IPv4 and IPv6 concurrently. QoS and dynamic traffic shaping can classify traffic using VPN, IP address, protocol, port, or QoS label, and adjust to modem capacity. Optional functions include header and payload compression, packet aggregation, GZIP compression, and byte caching. The FX5020e can combine separate satellite bandwidth segments into a virtual link, including segments on different bands or satellites. Accelerated TCP sessions are licensed in model-specific tiers; sessions above the selected tier pass through without acceleration. Comtech was founded in 1967 and is headquartered in Chandler, Arizona.
Who it suits
FX Series is aimed at ISPs, mobile network operators, satellite service providers, and communications service providers managing high IP traffic. It suits teams that need satellite-link acceleration, traffic control, or mobile backhaul support across IPv4 and IPv6.
What it does well
- Targets satellite links across GEO, MEO, and LEO.
- Accelerates 4G/LTE and 5G traffic in GTP tunnels.
- Classifies traffic using VPN, address, protocol, port, or QoS label.
- FX5020e bonds satellite capacity across bands or satellites.
- Provides web GUI, console, CLI, SNMPv3, and NetVue management.
- Fail-to-wire bypass and optional 1+1 system redundancy are supported.
What to know first
- Sessions above the licensed tier pass through unaccelerated.
- Pricing is available on request.
- Some redundancy features are unavailable on the FX1005ev.
Limits
Accelerated TCP sessions are limited by the appliance’s allocated license tier. Sessions above that tier pass through unaccelerated, subject to the appliance’s traffic forwarding capacity; some redundancy features are unavailable on the FX1005ev.
Plans
| Plan | Billed and limits | Price |
|---|---|---|
| FX Series WAN Optimization | License-based tiers by accelerated TCP sessions; FX1005ev: 2k–20k · FX1010e: 2k–40k · FX5020e: 10k–200k | On request |

Getting started
- Visit the Comtech FX Series WAN Optimization website.
- Choose an appliance model and accelerated TCP session license tier.
- Deploy the self-hosted appliance at both ends of the link for its Protocol Enhancement Proxy.
- Use the web GUI, console, CLI, SNMPv3, or Comtech NetVue to manage the system.
Verdict
Choose FX Series if your organization needs to optimize high IP traffic over satellite links or mobile backhaul, with traffic classification and compression. Check the model’s license tier and redundancy support against your requirements before choosing; sessions beyond the tier are not accelerated.
Questions
How is FX Series priced?
Pricing is available on request. Licensing is based on accelerated TCP sessions: FX1005ev tiers range from 2k to 20k, FX1010e from 2k to 40k, and FX5020e from 10k to 200k.
Which platforms does it support?
The listed platform is self-hosted.
What kinds of links does it target?
It targets satellite links across GEO, MEO, and LEO, using a Protocol Enhancement Proxy at both ends.
Can it support mobile backhaul?
It accelerates 4G/LTE and 5G traffic carried in GTP tunnels and supports concurrent IPv4 and IPv6 traffic.
How is the system managed?
Management interfaces include a web GUI, console, CLI, SNMPv3, and Comtech NetVue. SNMP and MIBs also support third-party network management access.
What happens above the licensed session tier?
Sessions above the appliance’s allocated tier pass through unaccelerated, subject to its traffic forwarding capacity.
