DS4004
Optical Ethernet Multiplexer
for NC4000 Fiber Node Platforms |
Aurora’s DS4004 Optical Ethernet Multiplexer enables delivery of Fast
Ethernet over fiber, interfacing with standard media converters such as CPE devices.
On the network side, the DS4004 is fully compatible with Aurora’s high speed digital
transport system and DWDM optical transport technology.
The DS4004 can be used over dedicated fiber or can operate over existing
digital return infrastructure, generating additional revenues from spare bandwidth in
these systems.
The DS4004 features one high-speed (2.125 Gbps) Network Port and four Fast
Ethernet Local Ports, all populated by SFP plug-in transceivers for ultimate flexibility
and affordability. SFP transceivers are available in a variety of transmit/receive
wavelengths, including dedicated 1310nm, 1550nm, CWDM ITU grid, and others. Each Local
Port supports a 100Mbps full duplex wire-speed Ethernet link that is terminated at the
customer premises by a standard media converter.
The DS4004 module includes a sophisticated add/drop multiplexing function
to serve its 2.125 Gbps Network Port, supporting software controlled add/drop of traffic
at 100Mbps granularity. This feature enables operators to add and drop only the amount
of traffic required per site, conserving valuable bandwidth. The DS4004 also includes a
Time Division Multiplexing function, serving the Local Ports to provide high degree of
security, low jitter and latency, and wire-speed performance to every customer port.
Features
• Compact multiplexer module for optical node platforms (occupies two node
slots – up to two modules in NC4000 series optical nodes or up to five
modules in an Ethernet Node)
• Services up to four customers per module, each with a
dedicated wire-speed full duplex 100Base-FX optical Local Port
• Time Division Multiplexing of traffic from the four Fast Ethernet Local Ports
into Aurora’s high speed (2.125 Gbps) digital transport optical Network Port
• All ports field configurable with a variety of SFP plug-in transceivers
(1310nm, 1550nm, CWDM, and others)
• Layer 1 transport device, transparent to Layer 2 and higher protocols,
including IEEE 802.1P, 802.1Q, 802.3u, VLAN, ToS, QinQ, and MAC-in-MAC
• Supports VoIP and other time-sensitive traffic with low latency and low delay
variation (jitter)
• Remotely managed via SNMP or Aurora’s EMS
• High degree of customer data security and isolation
• Environmentally hardened
• Hot plug in/out
