California access device start-up Tibit Communications has announced availability of what is billed as the world’s first fully pluggable Optical Line Terminal (OLT). The Tibit MicroPlug™ OLT is a complete network access device for 10 Gigabit Passive Optical Networking (PON). According to Tibit, the OLT dramatically reduces the footprint, power consumption, cost, and amount of application-specific hardware needed for network deployments.

The new OLT form factor is designed to revolutionise PON market dynamics by enabling switch vendors to easily extend their widely-deployed portfolio of 10G switch ports to support 10G PON. Tibit’s standards-based small-format pluggable (SFP+) solution reduces the physical footprint of today’s chassis-based and card-based solutions by 95% and lowers power consumption by 75%.

“Our challenge was to do something never attempted in this industry – reduce an entire OLT, including an entirely new ASIC and 10G optics, into a standards-based pluggable form factor,” said Richard Stanfield, CEO of Tibit Communications. “The result is a product that saves an extraordinary amount of space and power, and we are encouraged by the strong market reception of this game-changing device.”

Tibit’s MicroPlug™ OLT directly addresses the CapEx, OpEx, and network simplification objectives of service providers targeting next-generation architectures through Central Office Rearchitected as a Datacenter (CORD) and Network Function Virtualisation (NFV), and replaces legacy, PON-specific hardware equipment with a single network element. The reduced power and footprint profile of the MicroPlug OLT also meets the Distributed Access Architecture (DAA) objectives of cable operators. Multiple Tibit devices can effectively operate in an MSO remote node enclosure, satisfying strict environmental and power restrictions.

Mike Nielsen, VP Packet Software & Access R&D at Ciena noted: “Tibit’s MicroPlug™ OLT removes the costs and footprint of traditional OLTs from the carrier network while extending PON access into an array of environments. This revolutionary new device will help us advance our innovation agenda, particularly across our Packet Networking portfolio.”

Tibit’s in-band-by-design architecture can deploy in PON virtualisation environments such as virtual OLT – Hardware Abstraction (vOLT-HA), DOCSIS PON over Ethernet (DPoE), and Broadband Access Abstraction (BAA). The new OLT meets both 10G EPON and 10G GPON (XGS-PON) standards in a single device – IEEE 1904.1 and ITU-T G.9807.1.
