TG-Series – for Passive Optical Access Networks

The TG-Series is a family of cost-effective, passive optical WDM products. Designed for access applications, the TG-Series provides one of the most compact WDM access solutions on the market. The TG-Series fits in a wide range of applications, from controlled environments in central offices to street cabinets or even underground enclosures such as manhole applications that require environmentally hardened products.

The TG-Series supports point-to-point, mesh, bus and ring-based network topologies and can be used in a number of network scenarios such as Fiber to the Curb (FTTC), Fiber to the Building (FTTB) and high-security access networks. The optical modules come in a variety of form factors, including rack-mounted modules for central offices and street cabinets. Modules ideal for use in harsh environments like manholes are also offered.

The TG-Series is fully compatible and interoperable with the TM-Series and is managed with Enlighten management software (TNM). This gives network operators a simple upgrade path to fully active WDM solutions. Combined with parts from the TM-Series, it forms Infinera's iWDM-PON solution.
