Optimux-125 ( OP-125 ) Fiber Optic Multiplexer for 16-Channel T1 TDM and Ethernet 

The Key features of the Optimux-125 ( OP-125 ) Fiber Optic Multiplexer for 16-Channel T1 TDM and Ethernet include:

Up to 16 T1 links, full bandwidth 100 Mbps Ethernet traffic and high-speed data multiplexed into fiber optic uplink
25 Mbps or 125 Mbps operation modes
Single-mode, multimode, single-mode over single fiber, SFP-based interfaces
Range of up to 110 km (68 miles)
Optional additional hot-swappable power supply and uplink for redundancy

Optimux-125 / OP-125 in a campus application

RAD's Optimux-125 ( OP-125 ) provides a simple, flexible, and cost-effective solution for transporting multiple T1 links, high-speed data and Ethernet over fiber link, to distances of up to 110 km (68 miles).

RAD's Optimux-125 ( OP-125 )  features two license-activated operation modes:

In 25 Mbps operation mode, the units are fully compatible with Optimux-25.

In 125 Mbps mode, the products feature transport at 100 Mbps user Ethernet traffic.

The fiber optic link is available with single-mode, multimode, and single-mode over single fiber interfaces.

The Optimux-125 ( OP-125 ) uplink with fiber interfaces is proprietary in both device operation modes.

In 25-Mbps operation mode, the unit multiplexes up to 16 T1 links. The data rate of the TDM ports can partially be replaced (user-selectable) by the 10/100BaseT user Ethernet  traffic or by an optional high-speed data V.35 interface (see Table 1).

Optimux-125 ( OP-125 ) Uplink Interfaces

Various interfaces (based on SFP transceivers) are available for both the active and the backup uplinks (see Table 2 and Ordering Options):

1310 nm short or long-haul laser and 1550 nm long-haul laser interfaces for extended range over single-mode fiber

Single fiber interface using WDM technology, with the laser transmit signal at a different wavelength than the receive signal (1310 nm and 1550 nm).

Optimux-125 ( OP-125 ) Link Redundancy

Upon link failure, the unit automatically switches to an optional second uplink as a backup.

Optimux-125 T1 Interface
Optimux-125 multiplexes 16 T1 channels. The T1 interfaces comply with the ITU-T G.703. Line coding is HDB3 or B8ZS, respectively. A pair of LEDs monitors loss-of-signal and AIS on each T1 receive line.

OP-125 Fast Ethernet Interface
Optimux-125 feature fast Ethernet ports enabling a full 100-Mbps Ethernet connection in addition to the capacity of the 16 T1 channels. The Optimux-125 is supplied with a 10/100BaseT Ethernet USER port. This port is activated via a software key. The license can be purchased for 6-Mbps granularity to work in 25-Mbps operation mode, or for full bandwidth to work in 125-Mbps operation mode.

Optional V.35 interface available on Optimux-125 ( OP-125 )
The Optimux-125 can be supplied with one V.35 (2048/1544 kbps) channel that replaces channel 16 by user activation. The V.35 interface can only be used in 25-Mbps  operation mode.

RAD OP-125 timing
The OP-125 transmits each T1 channel separately so that the clock of each T1 channel is independent. The Optimux-125 supports internal and loopback timing modes. The 125-Mbps operation mode uses only Internal timing.

Typical applications for the Optimux-125 ( OP-125 )

Private Networks
In private networks, Optimux-125 shares campus services such as Ethernet, Voice, Data and Video in P2P (Figure 1) and Star topologies over dark fiber. Optimux-125 establishes TDM and Ethernet connectivity between the remote branches and headquarters for educational, financial, military sectors.

Traffic Backhaul Application
Optimux-125 transparently backhaul TDM & ETH traffic over fiber or coax uplink (see Figure 3).
OP-125s connect cellular base stations to controllers. This solution meets the requirements of cellular backhaul applications by providing TDM and Ethernet traffic for CDMA and GSM connectivity.
The Optimux-125 ( OP-125 ) units backhaul WiMAX traffic from remote locations over dark fiber links at a distance of up to 110 km (68.3 miles).

Optimux-125 ( OP-125 ) diagnostics
Optimux-125 ( OP-125 ) features comprehensive test and diagnostic capabilities that include local and remote loopbacks on the uplink interface and on each T1 port. A local loopback is also  supported on the optional V.35 user port.
To ease system diagnostics, Optimux-125 features LED status indicators and AIS alarm generation and recognition.
The OP-125 also feature dry contact closure upon link failure. An optional alarm port is available with dry relay contacts for major and minor alarms.

Management of the Optimux-125 ( OP-125 )
The Optimux-125 units can be configured and monitored with a number of management and diagnostic tools. An ASCII terminal and Telnet provide local management. Remote  management and diagnostics can be performed via a RAD Web-based management application or an SNMP-based management application. The products working in 25-Mbps operation mode can be managed RADview, RAD's SNMP-based management application.

Optimux-125 ( OP-125 ) Physical information
Optimux-125 is a compact, 1U-high unit. 
All the units can be mounted in a 19-inch rack.

The wide-range AC/DC power supply can be connected to either an AC power source (90 to 260 VAC), or a DC power source (40 to -72 VDC). The units may also be ordered with a +24 VDC (20 to 72 VDC) power supply. A second power supply can be ordered for power redundancy.
