100-Gigabit DWDM OTN MIC with CFP2

Software release

  • Junos 15.1F5 and later

Description

  • One 100-Gigabit DWDM OTN port

  • Power requirements (including transceiver) at different temperatures:

    • 55° C: 1.90 A @ 48 V (91 W)

    • 25° C: 1.73 A @ 48 V (83 W)

  • Weight: 2.3 lb (1.04 kg)

  • Model number: MIC3-100G-DWDM

  • Name in the CLI: 1X100GE DWDM CFP2-ACO

Hardware features

  • Dual-wide MIC that installs into two MIC slots

  • Supports CFP2 analog coherent optics (CFP2-ACO)

  • Transparent transport of a 100-Gigabit Ethernet signal with OTU4V framing

  • ITU-standard OTN performance monitoring and alarm management

  • Dual-polarization quadrature phase shift keying (DP-QPSK) modulation

  • Supports three types of forward error correction (FEC):

    • Soft-decision FEC (SD-FEC)

    • High-gain FEC (HG-FEC)

    • G.709 FEC (GFEC)

  • 100 channels on C-band ITU grid with 50-GHz spacing

  • Latency:

    • SD-FEC: 14 µs (TX + RX)

    • HG-FEC: 22 µs (TX + RX)

    • GFEC: 6 µs (TX + RX)

  • Interoperable with the CFP-100GBASE-ZR transceiver supported on the 100-Gigabit Ethernet MIC with CFP (MIC3-3D-1X100GE-CFP) on MX Series routers and the 100-Gigabit Ethernet PIC with CFP (P1-PTX-2-100GE-CFP) on PTX Series routers.

Note:

The 1-port 100-Gigabit DWDM OTN MIC is not directly interoperable with the 2-port 100-Gigabit DWDM OTN PIC (P1-PTX-2-100G-WDM), but they can both operate over the same DWDM line system.

Software features

  • Compliant with ITU G.709 and G.798

  • Provides a transport interface and state model (GR-1093)

  • Performance monitoring features such as alarms, threshold-crossing alarms, OTU/ODU error seconds and FEC and bit error rate (BER) statistics

  • SNMP management of the MIC based on RFC 3591, Managed Objects for the Optical Interface Type, including the following:

    • Set functionality

    • Black Link MIB

    • IFOTN MIB

    • Optics MIB

    • FRU MIB

  • Pre-FEC BER monitoring provides interrupt-driven, BER-based detection of link signal degradation for MPLS fast reroute.

  • User-configurable optics options:

    • Transmit (TX) laser enable and disable

    • TX output power

    • Wavelength

    • Receive (RX) LOS warning or alarm thresholds

    • Threshold crossing alarms (TCAs)

    User-configurable card options:

    • FEC mode (SD-FEC, HG-FEC, or GFEC)

    • TCAs

Cables and connectors

Fiber-optic 100-gigabit CFP2-ACO transceiver

  • Connector: Duplex LC/UPC

  • Model number: TCFP2-100G-C

Note:

When inserting the C form-factor pluggable 2 (CFP2) transceiver, ensure that the transceiver sits tightly in the port. You hear a distinct click sound when the latch locks into the corresponding port. The latch must be fully engaged in the corresponding port for the CFP2 transceiver to function properly. Failing to do so can result in loss of connection.

To verify that the CFP2 transceiver module is inserted properly, give a gentle pull by grasping the sides of the module. The module should sit tightly.

LEDs

OK/FAIL LED, one bicolor:

  • Off—MIC is powered off.

  • Green—MIC is initialized and online, functioning normally.

  • Amber—MIC is coming online, or is in fault state.

LINK LED, one bicolor per port:

  • Off—Port is offline.

  • Solid green—Link is up.

  • Red—Port failure is detected.

Note:

The port is labeled Port 0.
