1455 OFA (Optical Fiber Amplifier)
Meriton Networks has a full suite of next-generation optical amplifiers that feature extended variable gain range, superior noise figure and gain flatness to optimize the optical performance in the network. The 1455 OFA can be used for regional applications, supporting distances up to 600 km. It is also ideal for applications requiring mid-stage insertion of dispersion compensation or when out-of-band direct Ethernet management access to the line amp sites is not available. The automatic gain control (AGC) and fast transient response of the amplifier enables dynamic wavelength provisioning and versatility. The 1455 OFA is a 2RU rack-mount unit which includes an integrated redundant DC power supply.
Variable Gain
The variable gain of the amplifiers enhances the network flexibility allowing a wide range of span loss combinations to be supported within a single platform. When a span loss change occurs as a result of a fiber cut and repair, the adjustable gain can be used to reset the network to the optimal operating point. The amplifiers have an adjustable gain range of 10dB.
Transient Suppression and Automatic Gain Control
The amplifiers provide fast transient suppression by controlling the overshoot and undershoot and can respond to the most drastic power changes with overshoots or undershoots of less than 0.5dB. Automatic gain control maintains a constant gain by monitoring the input power and adjusting the optical pump power. The amplifiers ensure that optimum pump power is applied to rapidly suppress any transients.
Gain Equalization or Flatness
The 1455 OFA provides +/-0.75dB gain flatness (with an additional tilt control feature) and less than 6dB typical noise figure across the C-band. These characteristics enable long optical links by cascading multiple amplifiers while still providing excellent optical signal to noise ratio (OSNR). The superior noise figure and gain flatness performance is maintained across all input powers and gain settings.
Network Management
The amplifiers provide full remote monitoring, configuration and upgrade capability through a local SNMP, and TL1 interface. Remote connection is supported via 10/100 Mb/s Ethernet ports. The Meriton Networks 8600 NMS (Network Management System) manages the amplifiers via the Ethernet port, receiving fault data, and offering cut-through GUI interface support.
1455 Raman Amplifier
Meriton Networks provides additional reach extension over and above the 1455 OFA with its Raman amplifier product. The Raman amplifier can extend the reach of a 1455 OFA network from 600km to more than 800km. It is typically employed where span losses are greater than the maximum supported by the 1455 OFA, to provide significant OSNR improvement, or in cases where there is a requirement to skip huts between network element locations. The Raman amplifier is a fully managed 1RU rack-mount unit that can deliver variable gain up to 10dB on G.652 fiber and up to 13dB on G.655 fibers.
OSNR Improvement
The Raman amplifier configured as a counter-propagating distributed pump, provides OSNR improvement for long fiber spans without introducing additional non-linear impairments that would result from boosting the channel powers at the transmit end of the fiber.
Laser Safety
The Raman module employs multiple, independent parallel laser safety mechanisms. This allows the amplifier and the network within which it is installed to be classified as class 1M laser products.
Auto Shut Down/Start Up
The unit monitors line conditions and will automatically power down the pump lasers in the event of a fiber cut. The unit will also detect when the fiber cut has been repaired and automatically power up to the provisioned gain setting prior to the fiber cut.
Network Management
The 1455 Raman amplifier provides full remote monitoring, configuration and upgrade capability through a local SNMP interface. Remote connection is supported via 10/100 Mb/s Ethernet ports. The Meriton Networks 8600 NMS (Network Management System) manages the amplifiers via the Ethernet port, receiving fault data, and offering cut-through interface support.
1100 DCM (Dispersion Compensation Module)
The Meriton 1100 DCM series is an optimal solution to efficiently correct the effect of chromatic dispersion on single mode fiber at both 2.5 Gb/s and 10 Gb/s across the entire C-band. The 1100 DCM features 100% dispersion slope compensation, low insertion loss and polarization mode dispersion. The 1100 DCM is a fully passive 1RU rack-mount unit, with the ability to hold two standard-length (40 km, 60 km or 80 km) DCM modules or one extended-length (100 km or 120 km) DCM module. The DCM modules are easily removable for ease of upgrade and swapping. DCM standard-length modules can be configured for separate east/west ring applications or combined together for additional dispersion compensation.
Applications
- Longer reach 2.5 Gb/s & 10 Gb/s metropolitan optical networks
- Post-compensation at the optical receiver module
- In-line compensation at the Meriton Networks 1455 OFA line amplifier
- Pre-compensation at the optical transmit site
The 1100 DCM Series is available in these distances for SMF and LEAF fibers:
1104 DCM 40 km
1106 DCM 60 km
1108 DCM 80 km
1110 DCM 100 km
1112 DCM 120 km
