OC12c Transceiver (OC12c-XCVR)
The Optical Carrier Level 12 Transceiver (OC12c-XCVR) plug-in card has more bandwidth for more revenue generating services and transport. It functions as an uplink to an ATM network and as a high-rate, point-to-point transport between Tellabs 1000 MSAP series terminals. The OC12c-XCVR card is compatible with SONET OC-12c standards per GR 253-CORE. The OC12c-XCVR plug-in card has a 622 Mbps fiber optic interface using Intermediate Range Optics. Both a transmitter and a receiver are on a single card.

Features and Benefits

  • Provides a full 622 Mbps physical interface on 1310 nm single-mode fiber for its OC12c interface using two fibers - one transmit and one receive
  • Functions as an uplink to an ATM network or an inter-terminal transport.
  • SONET Automatic Protection Switching (APS) 1+1 enabled when provisioned as an uplink
  • GR-253 Intermediate Reach compatible (GR-253-CORE)
  • Supports 2048 virtual channel connections
  • Dual-memory for non-service affecting programming
  • SC Connectors for easy installation

Included Highlights

High Availability

High network availability is supported with the by equipping a Tellabs 1000 MSAP system with two (2) OC12c-XCVR plug-in cards. This configuration assures system, card level and per port level redundancy.

Flexible Transport

As a general purpose interterminal transceiver, the OC12c-XCVR carries both TDM and ATM traffic: TDM traffic is converted to ATM cells. 50 Mbps are reserved for the TDM backplane. The OC12c-XCVR contains Tellabs’ next generation ASIC, the Pathfinder, which is a key differentiator and technology enabler providing access to the ATM cell bus. The Pathfinder functions as an “ATM switch on a chip” providing ATM switching, QoS, concentrator capabilities, and conversion of TDM traffic to ATM and back to TDM.

Video Delivery

As a video uplink to the ATM data network, the OC12c-XCVR interfaces to any UNI 3.1 and UNI 4.0 compliant ATM switch or router. As an ATM uplink, the card supports a 500 Mbps payload for use as a video network uplink. Automatic Protection Switching (APS 1+1) is enabled when the card is provisioned as an uplink.

Low Power and Thermals

The OC12c-XCVR card uses powering and heat dissipation technologies available in the Tellabs 1000 MSAP terminal can operate in any of the shelf’s 22 general purpose slots.
