Eight bi-directional GigE ports:
-
Each GigE port supports small form factor pluggable (SFP) (16mm H x 42mm D) optical
modules with a data rate of 1.0625Gbps according to IEEE-802.3z.
-
Each GigE port supports either single mode or multimode SFP optical modules (the NPM
supports both types simultaneously), and operates on frequencies compliant with the optical
channel plan defined in ITU G.692, 100 GHz channel plan appendix IV.
-
The NPM supports SFP modules with wavelengths of SX 850nm for short distances up to
65 meters, LX 1310nm for medium distances up to 10 kilometers, or LX 1550nm for long
distances up to 70 kilometers.
-
The GigE port also supports SFP copper modules of full duplex 1000BaseT Ethernet with
copper interfaces that are compliant with IEEE-802.3ab. The copper SFP module supports
distances up to 100 meters.

NPM: Two 10GigE ports
NPM2: Four 10GigE ports
-
Each 10GigE port supports pluggable 10 Gigabit small form factor pluggable (XFP) (23.5mm H
x 67mm D) optical modules that are IEEE-802.3ae compliant with data rates of 10.3125Gbps.
The NPM supports XFP modules with wavelengths of 850nm for distances from 26 meters to
300 meters, depending on the grade of fiber, and 1310nm for distances up to 10 kilometers.
-
Each 10GigE port receives input as MPEG-2 SPTS and MPTS with unicast or multicast, de-jitters
up to 100ms of network jittering and routes the video or data streams to the appropriate
application module (VPM, TCM, AMP).
-
The 10GigE ports can handle either constant bit rate (CBR) or variable bit rate (VBR) MPEG-2 as
well as H.264 digital video streams in both SD and HD format, then deliver the processed video
content over MPEG-2TS / UDP / IP / GigE or MPEG-2TS / RTP / UDP / IP / GigE unicast or
multicast IP transport.
•
NPM only: One Fast Ethernet (10/100BaseT) Management port for management and control,
including SCTE 30 messages.
•
One RJ-11 serial console interface for management access and event logging.
•
Reset button.
