OC-12 optical interface circuit pack

(NTN404AA, BA, CA, DA, JA, KA, LA, MA)
Four OC-12 circuit packs, OC-12 IR (NTN404KA), IC (NTN404MA), LR
(NTN404JA), and ER (NTN404LA) support the VT1.5, STS-1, STS-3c, and
STS-12c signal rate as well as STS-12c performance monitoring.
OPTera Metro 3500 continues to support the OC-12 IR (NTN404BA), IC
(NTN404DA), LR (NTN404AA), and ER (NTN404CA) optical interface
circuit packs, which support the VT1.5, STS-1, and STS-3c, signal rates and
associated PMs.
The central wavelength of the transmit optics is 1310 nm for the Interconnect
and LR optical reaches, and is 1550 nm for the ER optical reach.
Optical transmit
The OC-12 interface receives one STS-12 or STS-12c from each STX and
VTX-series circuit packs. The OC-12 interface converts the STS-12 or
STS-12c into an OC-12 optical signal. The OC-12 optical signal is then
transmitted on the optical transmit channel.

Note 1: The OC-12 circuit pack is considered a core circuit pack when
provisioned in slots 11 and 12. In addition, the OC-12 circuit pack can be
used as a tributary circuit pack when provisioned in slots 3 to 10.
Note 2: The VTX-48e circuit packs supports the OC-12 line rate for the
optics in slots 11 and 12.
