Ultra Optical System
T700 Series Transponder/Muxponder
Compact, Modular Transponder & Muxponder blade for 100G to 800G transport
The T700 Series includes the T700 and T750 transponders. These compact, modular transport blades support transponder, muxponder, inverse‑muxponder, and regeneration functions for cost‑effective bandwidth scaling.
Supporting 100G through 800G services with a wide range of neutral‑host pluggable and discrete optical options, the T700 Series adapts to evolving network requirements without requiring hardware redesigns.
The T700 and T750 offer similar functionality, with the key difference being power: the T700 is DC‑powered, while the T750 supports AC power.

Flexible Transport Options & Expedited Pluggable Economics
The T700 Series supports multiple Plug-In Unit (PIU) options, allowing operators to tailor each blade to their deployment model. This flexibility allows operators to adopt cost-effective pluggable optics from any vendor or maintain support for traditional coherent designs when needed.
Pluggable and discrete options include:
• All-pluggable neutral host supporting multivendor DD800 form-factor with 400ZR/ZR+ and 800ZR/800ZR+ modules
• Discrete network optics with support for CFP2-DCO and fully tunable coherent optics
• Supports both C-band and L-band operation
• Mixed PIU configurations on a single blade to optimize cost and performance
Multiple Transport Functions in a Single Blade
The T700 Series is designed to support diverse network architectures and functions, including:
• 400G, 600G, and 800G transponder configurations
• 100G and 400G muxponder services
• Regeneration for extended reach and network optimization
Scalable Architectures With the Ultra Optical System
For larger deployments, the T700 Series can be integrated with the Ultra Optical System C200 Communications Integrator, consolidating up to 36 blades into a single logical node with one IP address for simpler control and faster deployment.
The T700 Series can also be deployed within the Ultra Optical System Housing, which provides redundant power distribution, integrated power distribution units, and lower installation and operational costs for multi-blade sites.
T700 Series Frequently Asked Questions
The T700 Series is a compact, modular optical transport blade that supports transponder, muxponder, inverse‑muxponder, and regeneration functions for 100G to 800G services in metro, regional, and long-haul networks.
Choose the T700 Series when you need to scale capacity from 100G to 800G without committing to a single optics model. This is ideal if you want to adopt coherent pluggables on your timeline, support open architectures, maximize density in limited rack space, and simplify operations across metro or regional networks. The T700 is especially well suited for Open ROADM environments, network modernization projects, and deployments where flexibility, cost efficiency, and long‑term scalability matter as much as peak performance.
Plug-In-Units (PIUs), fans, management optics, and rails are common between the T700 and T750. The main difference is the T700 is DC‑powered, while the T750 supports AC power.
Yes. With the all‑pluggable P7B1 PIU option, the T700 supports standards‑based coherent pluggables, including 400ZR/ZR+ and 800ZR/ZR+, on both client and network ports.
The T700 series supports discrete, full-band tunable, coherent network optics (P7A-series PIUs), enabling greater reach. Pluggable network optics, including CFP2-DCO (400ZR+) and -DD800 (400ZR/ZR+, and 800ZR) are supported by the P7A5 (CFP2) and P7B1
(-DD/-DD800). The family of PIUs together offer great configuration flexibility when you need it.
Yes. The T700 allows pluggable and discrete PIUs to be mixed within the same blade, enabling operators to optimize each link based on reach, cost, and network requirements.
