An upstream reach-extender for 10Gb/s PON applications based on an optimized semiconductor amplifier cascade
Optics Express, 2012
We present a reach-extender for the upstream transmission path of 10Gb/s passive optical networks based on an optimised cascade of two semiconductor optical amplifiers (SOAs). Through careful optimisation of the bias current of the second stage SOA, over 19dB input dynamic range and up to 12dB compression of the output dynamic range were achieved without any dynamic control. A reach of 70km and split up to 32 were demonstrated experimentally using an ac-coupled, continuous-mode receiver with a reduced 56ns ac-coupling constant.

SOA-BASED NOISE SUPPRESSION IN SPECTRUM-SLICED PONs: IMPACT OF BIT-RATE AND SOA GAIN RECOVERY TIME
Spectrum-sliced wavelength division multiplexing is becoming an attractive cost effective candidate for future passive optical networks. Since incoherent sources are used, excess intensity noise limits the achievable performances. Here, we propose to use semiconductor optical amplifiers (SOA) to mitigate this noise. We experimentally investigate the advantages and drawbacks of placing the SOA-based noise reduction at the optical line terminal (OLT) as well as at the optical network (ONU) unit (user end side). Two SOAs with different gain recovery times were used at different bit rates. Results show that if the SOA is placed at the ONU, fast SOAs are the most efficient for noise reduction. On the contrary, if the SOA is at the OLT, slow SOAs represent a better solution for noise cleaning, since they introduce less performance penalty.
Amplified gigabit PON systems [Invited]
Journal of Optical Networking, 2007
We describe how a passive optical network (PON) extender box can be implemented at standard PON wavelengths (1310 and 1490 nm) using either optical fiber amplifiers (praseodymium and thulium) or semiconductor optical amplifiers to further increase the physical reach and split of a current standardized PON system such as a G-PON or GE-PON. The transparency to PON protocol of this approach means no changes to the existing standards are required. This is attractive as operators and vendors are keen to fully exploit the investment made in current PON standards.

Optical Power Budget Enhancement in 50–90 Gb/s IM-DD PONs With NOMA-CAP and SOA-Based Amplification
IEEE Photonics Technology Letters, 2020
We report experimental results of a semiconductor optical amplifier (SOA) for optical amplification in a 50-90 Gb/s IM-DD optical access system using non-orthogonal multiple access multiplexing combined with multi-band carrierless amplitude phase modulation format (NOMA-CAP). Specifically, the SOA has been investigated as both booster and preamplifier for downstream applications in PONs. The measured optical power budgets resulting from performing booster amplification and preamplification simultaneously, assuming a BER threshold at 2.2x10-3 , are 28.7(23.7) dB and 23.6(18.9) dB at 50(90) Gb/s for the strong and weak NOMA levels, respectively, compared to the budgets for the strong and weak NOMA levels of 12.4(8.7) dB and 9.4(5.2) dB when no optical amplification is used.
The Super-PON concept and its technical challenges
Broadband Communications, 1996
This paper describes the architecture and the technical challenges for the design of a large-split and long-range Passive Optical Network (PON) intended for Fiber-To-The-Home (FTTH) deployment. The system, called Super-PON, can support a splitting factor of 1024 (or more but with a more complex and hence costly implementation) and a range of 1 00 km. The overall network capacity is 2.5 Gbps TDM downstream and 300 Mbps ATM-based TDMA upstream. As compared with already designed PON systems, the proposed Super-PON requires the introduction of optical amplifiers along the fiber paths. The presence of these optical amplifiers brings new technical challenges especially for burst mode amplification in the upstream direction of transmission. Analysis and potential solutions to solve these problems while allowing further capacity upgrades using WDMIWDMA techniques are described in this paper along with a discussion of network survivability issues.

L-band in-line remote amplification for an extended WDM/PON ring architecture
… Optical Networks, 2009. …, 2009
In this paper, a study on a fully passive WDM/PON ring architecture which reaches 19 km distance, while serving more than 1000 users with symmetric several hundred Mbit/s per user is presented. The design is based on SARDANA (Scalable Advanced Ring -based Passive Dense Access Network Architecture) and was generated as an alternative solution, with its novelty laying on the use of L-band in line remote amplification. The simulation of an extended access WDM/TDM PON formed in a double fibre ring with single fiber trees was created. The network's operation has been tested for several conditions of usage (i.e. maximum number of users, transmission power and pump power) and an optimization of the design has been performed. The target was to achieve, with given transmission and pump power, the reach of more then 1000 users with input power high enough to permit the use of an RSOA at the ONU. The use of L-band signals and special doped fiber has permitted the effective use of RSOAs in the total of the end users.

High Customer Density PON With Passive Amplification Through Distributed Pump for <formula formulatype="inline"><tex Notation="TeX">${>}$</tex> </formula>1:1000 Tree Split
Journal of Lightwave Technology, 2011
A network architecture for tree-like passive optical networks (PONs) with high splitting ratios is proposed and experimentally demonstrated. Splits are shown to be feasible thanks to a noise-powered amplifier that is built-in inside the power splitter. The proposed noise pumping technique recycles the natural amplified spontaneous emission (ASE) of a semiconductor optical amplifier at the customer premises, avoiding the use of an electrical power supply in the fiber plant. The impact of the location of this noise-powered extender box inside the signal distribution element of the tree is analyzed in terms of obtained signal gain, ASE accumulation among multiple extender boxes, and transmission performance. Finally, full-duplex transmission at 10 Gb/s with burst-mode upstream is demonstrated in a particular scenario with a split of 1:1000 and a loss budget of 39.5 dB, revealing that power margins of dB can be provided.

Fiber Powered Extender for XG-PON/G-PON Applications
Journal of Optical Communications and Networking, 2014
This work proposes a new approach to power passive optical network (PON) extenders using the powerover-fiber technique, turning them virtually passive. This approach eliminates the batteries in the remote sites, improving the reliability and the security of the system. The limits and the perspectives for this approach are discussed in this work. The performance of fiber powered semiconductor optical amplifiers based on the extender is shown with a 10 gigabit passive optical network (XG-PON)/gigabit passive optical network (G-PON) system setup using a 1∶32 splitter and 50 km reach. The conventional method to power the extenders is also presented for the sake of comparison with the proposed powerover-fiber technique.
Saturated collision amplifier reach extender for XGPON1 and TDM/DWDM PON
Optics Express, 2011
Saturated Collision Amplifier (SCA) is a novel amplification scheme that uses SOA saturation in order to maximize the output power and minimize the ASE noise and the polarization sensitivity. We demonstrate the SCA reach extension in a commercial single-wavelength XGPON1 prototype system where bidirectional optical budget of up to 50 dB is obtained. The traffic performances are compared between the SCA and the conventional SOA extender. The novel extension scheme is demonstrated also for two-and four-wavelength 10 Gbit/s unidirectional downstream configurations with 45 km and 100 km transmission distances with 58-dB maximum total optical budget for each wavelength.
SOA AT 1550 nm TESTING IN BIDIRECTIONAL PON
Semiconductor optical amplifiers (SOA) have become more popular in optical networks. We tested if SOA can be used in the bidirectional passive optical network (PON). The measure-ment was focused on possibilities of using SOA designed for 1550 nm in the laboratory PON working with wavelengths of 1490/1550 nm for the downstream traffic and 1310 nm for the up-stream traffic. The influence of the driving current and the temperature on the gain was tested. A measurement at working wavelengths was aimed at verifying the spectral width of SOA. The measurement has shown that an individual amplifier for each separate direction must be used.
Entirely passive coexisting 10G-PON and GPON compatible reach extender using Raman amplification
Optics Express, 2012
This paper describe a truly-passive coexistence of 10G-PON and GPON compatible reach extension system with a novel optical configuration, by using laser pumps to provide reverse-pumped distributed Raman gain for both 1270nm 10G-PON and 1310nm GPON upstream (US) signals, and using semiconductor optical amplifiers (SOA) as boosters to improve the loss budgets for both 1577nm 10G-PON and 1490nm GPON downstream (DS) signals. The Raman interaction between laser pumps and the two US signals is investigated, and the system transmission penalties of US signals due to Raman ASE noises is measured. The transmission impairments of 1490nm DS signals due to pattern-dependent distortion caused by gain dynamics of the SOA is discussed in this paper. Finally, we present experimental demonstration of coexisting 10G-PON and GPON bidirectional transmission over 50-km of AllWave TM fiber with entirely passive fiber plant and a total 1:96 split, accommodating link loss budget more than 39-dB for both 10G-PON and GPON US signals.

In this work we propose a WDM PON migration from FTTB to FTTH access by employing bidirectional amplification by a linearized semiconductor optical amplifier. We demonstrate that a semiconductor optical amplifier placed at the entry of a group of ONUs sharing the same wavelength can boost the loss budget allowing to compensate for the losses of a passive splitter up to 1:16 division rate, allowing to upgrade existing WDM PONs FTTB structures to permit the fiber to reach the final user's home.
