Optimux-45, Optimux-45L
Multiplexers for 21E1/28T1 over Fiber or T3• Up to 28 T1 or 21 E1 channels multiplexed into a single 45 Mbps data stream

Any Traffic over Fiber• Combination of T1 and E1 channels• Transmission over coax or fiber optic cable• Range up to 110 km (68 miles)• Ring and chain configurations (Optimux-45 only)

The Optimux-45 and Optimux-45L fiber
optic multiplexers provide a simple, flexible
and cost-effective solution fortransporting multiple E1 and T1 signals atdistances of up to 110 km (68 miles).

This provides an easily configurable
solution, flexible enough to meet thespecific requirements of a broad range ofapplications.

The multiplexers integrate up to 21 E1, 28
T1 or combination of E1 and T1 channels,
over a single 45 Mbps data stream.

The Access Company

Optimux-45, Optimux-45L
Multiplexers for 21E1/28T1 over Fiber or T3

Each of the E1/T1 channels is independentand can use a different clock.
The units are interoperable with RAD’s
FOM-T3 and FOMi-T3 devices.
Optimux-45 and Optimux-45L conform toITU G.703, G.747, G.823, G.824, ANSI
T1.107, T1.404, RFC3895, RFC3896
standards.
UPLINK
Two Optimux-45/45L units can beconnected using WDM (WavelengthDivision Multiplexing) or bidirectional
technology over a single fiber (SF) link,
thus reducing fiber cable costs by 50%.
The following optical interfaces areavailable for the fiber main link:•850 nm VCSEL for multimode fiber•

1310 nm LED for multimode fiber•

1310 and 1550 nm laser for extended
range over single mode fiber•

1310 and 1550 nm laser for single
fiber WDM operation•

1310 nm laser for single fiber/single
wavelength operation.

TRIBUTARY CHANNELSMANAGEMENT

Optimux-45 and Optimux-45L are available
with either balanced or unbalanced
tributary ports.

Optimux-45/45L can be configured andmonitored locally using an ASCII terminal
connected to the control port or remotely
via the Ethernet management port using:

Optimux-45 is available with 4, 8, 12, or
28 RJ-45 connectors or with 21 mini-BNC
connectors.
Optimux-45L is provided with two 64-pin
Telco connectors for balanced or
unbalanced tributary ports.
NETWORK TOPOLOGY(OPTIMUX-45 ONLY)•

RADview-EMS running in a
Windows or Unix environment•Web-based remote access terminal•

Telnet.

Inband management of a remote
Optimux-45/45L unit is performed via thefiber optic/coax uplink.

Optimux-45 supports chain and ring
configurations, facilitating several E1 or T1
services at each node.
In ring topology (see Figure 2, Figure 4),
Optimux-45 provides a full path protection
mechanism that enables the nodes tomaintain all communication services, evenin the event of a link failure.
Special partially equipped versions areavailable for ring and chain applications
with different number of tributarychannels (see Table 1 for detail).
Ring or chain configuration is performed
using RADview network management
system.

DIAGNOSTICS
To facilitate system diagnostics,
Optimux-45/45L features LED statusindicators, AIS alarm generation, alarm dry
contacts interface, and diagnostic
loopbacks on the E1/T1 and T3 links.
REDUNDANCYWhen required, critical hardware
components can be backed up. Thisensures that any single point of failure will
not disrupt the entire system. An optional
hot-swappable second main link provides
backup, using automatic switchover upon
link failure. An optional second power
supply provides power redundancy for
fail-safe operation.
PHYSICAL
Optimux-45 and Optimux-45L are available
as compact 1U-high units that can bemounted in a 19-inch (ANSI) or ETSI rack.
