CommScope’s FIST™MSC - all-in-one fibre splice closure
A significant challenge that network operators face is the ability to respond quickly to new market conditions - they need speed to market when rolling out new equipment and services. Controlling labour and training costs are necessary for efficient deployment. It can be difficult to ensure that the right people with the right training are available at the right time. CommScope’s FIST™ helps customers respond to future changes while delivering unparalleled reliability. The new
closure brings all-in-one versatility to networks because it works with the widest range of cable types while maintaining easy access to the individual fibres within those cables. It is both reliable and versatile, accommodating new technologies, new topologies, and installation requirements in the feeder and distribution portions of the network. • Gel sealing technologies: Composed of eight interchangeable and wrap around cold-seal segments that are field and factory installable.
1-27mm cables. • FIST fibre management: Single circuit and single- element splice trays with high levels of performance at high splice capacity. • Easy install: Removable base with easy access during installation and provisioning. Finding fibre deployment efficiencies is key to outpacing the competition. Consumers today have an unprecedented amount of control in their relationship with providers, and subscriber satisfaction has become paramount to avoid customer churn. The FIST™ modular splice closure is a
solution that is efficient right out of the box! Find out more at www. commscope.com

iXblue: OOK and DPSK modulation formats evaluation for high data rate laser communication in space
iXblue with its partners Airbus D&S and CILAS recently built an engineering bread board (EBB) model of a laser communication system dedicated to high data rate transmission in space. The aimed application was focused on feeder links between low earth orbital (LEO) satellites and ground stations. The goal was to carry out a full evaluation of a WDM (Wavelength Division Multiplexing) communication system in the C-band infra- red window. The demonstration was based on four main building blocks: a transmitter Tx, a receiver Rx, a 5W high power optical amplifier
(HPOA) and a digital processing unit (DPU). Data rates up to 25 Gb/s per channel were evaluated using two different modulation formats: OOK and DPSK. iXblue oversaw the integration of the ModBox Tx module with its TRL-9 lithium niobate Mach- Zehnder modulators, its RF modulators drivers and related bias controllers. The ModBox Rx incorporated the iXblue low noise optical amplifier (LNOA) build with RadHard erbium doped optical fibres, the photoreceivers for the OOK detection and the differential photoreceivers connected to optical delay lines for the DPSK demodulation. The bit error rate (BER) characterization was investigated
with up to three WDM channels to determine the best trade-off in terms of power consumption, data rate and design complexity. The use of the HPOA was also investigated. Four Wave Mixing
(FWM) was investigated. The full analysis of the characterization campaign allows us to determine the best configurations for multi Gb/s upstream and downstream optical communications in space.
